<div class="MsoNormal">
Hello Everyone,</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
I have finally replaced the EnJYN Scuba tank based system
with a custom stainless steel vessel.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The Joe Blow</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
These can be used to slowly flow through supercritical CO2
at up to 1800PSI, and the pressure vessels can be filled, sealed off, and
heated to achieve up to 4000PSI.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
I am only offering a 3oz size and an 8oz size to be used at
home. Larger capacities will only be offered in closed loop reclaiming systems.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The 3oz I am selling $1299 and the 8oz for $2195</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Finally, an added and unintentional bonus is that by
removing the quick connect from the hose and upper plug, cans of butane can be
used if desired. Both supercritical carbon dioxide extracts and butane
dissolved extracts can be made in this set-up without modification.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
</div>
<div class="MsoNormal">
The collection container now included is twice the diameter
of the one in the video below, this allows the carbon dioxide to
evaporate/sublimate from the essential oil more readily. The additional benefit
is the ease of removing the extract from the container.</div>

<div class="MsoNormal">
This new method and design is using one continuous
extraction at pressures of 1800PSI and below (Actually I capped it at 1500PSI).
The temperature and pressure ratings of the aluminum storage vessel are never
exceeded at any point.</div>
<div class="MsoNormal">

<div class="MsoNormal">
My stainless steel design allows for up to 3800PSI and so if
desired it can be sealed and heated much like the SCUBA tank. That is not the
intention, however. This system is meant for convenience for the small
commercial market.</div>

<h2>
<span style="color: blue;">Challenges Of Low-Cost CO2/Finding My Market</span></h2>
</div>
<div class="MsoNormal">
Wednesday, January 15, 2014 2:00 AM</div>
<div class="MsoNormal">
As I am finding my place in the market, I have decided to
turn away from large commercial systems and release and offer a mid level
system for commercial interests. From correspondence and research, the majority
of small to medium commercial operations desire a machine for less than $10K
that can handle a suitable amount of plant material (1-3lbs) and process it in
one day or less, at as low of a temperature as possible.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The simplest way to make this happen at low cost, is to use
a system that does not rely on a mechanical pump to supply the force needed for
extraction as well as movement of solvent through the system. </div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
There are challenges with this type of design, however.
First, the solvent is not reclaimed, and so maximizing the use of the solvent
is critical. This is what lead me to use SCUBA tanks because after researching
solubility of essential oils in SCCO2 I learned they are more soluble when the
solvent is at higher pressures, temperatures, and densities. The negative to
this is that the plant is not continuously extracted. It is extracted in
iterations of a process, or "runs", and so takes much more time to
complete.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The second issue is simply the amount of solvent that is
exposed to the plant, is much less than with pump systems. In a pump design the
plant material can come into contact with hundreds or thousands of pounds of
the solvent because it is continuously pumped and distilled through the
extractor. In passive extractions that done in sets, the amount of solvent in
contact with the plant is limited by the volume of the pressure vessel, and the
number of runs conducted on the same plant material. </div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
A third challenge is temperature. Due to the inability to
easily force larger masses of carbon dioxide into fixed volumes at any fill
level desired, heat alone must be used to achieve the high pressures needed for
extraction. I control this to an extent by warming the storage vessel as I fill
my extraction tanks to force a slight overfilling of the cylinder. This allows
somewhat lower temperatures to be used for extractions.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
You have to face facts, if you do not invest a larger amount
initially in a reclaiming extractor, it will cost more per extraction because
of the solvent requirements. Thankfully, the solubility of most essential oils
are such that it makes great economic sense even if the solvent is not
reclaimed.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
So, with all of these considerations in mind. I have
developed a pass through stainless steel extractor. It is something that can be
attached inline to the EnJYN transfer assembly and collection container, should
previous customers desire to move up in production level. All you will need is
a source of liquid CO2 and your herbs.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The current design allows simple, one-step extractions, in
stainless steel vessels. Meaning acidic or wet material is not a problem where
corrosion is concerned. So all manner of plant, citrus fruit, seeds, etc can be
extracted this way. You open a valve and allow the solvent to flow, at the end
you scrape out your extract and that's it. </div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The extractions will be below 1800PSI and 120F (standard
CGA320 limits) unless higher pressure and temperature is desired. The ability
to fill, and seal the extractor to achieve higher temp and pressures is there,
but not required. Why this is desireable is that after a long pass through
extraction at low temp and pressure, which will pick up almost all terpenes and
some heavier essential oils, you can do two or three short 10-15min higher
pressure iterations at up to 3200PSI to collect waxes and the final yield from
your plant. In this manner high yield can be achieved, while preserving and
collecting the delicate aromatics in the early part of the extraction. </div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Although this method is not quite as efficient in the use of
CO2 compared with my SCUBA method, it seems that most are more turned off by
high temperatures and lengthier extractions, than using a little more solvent.
CO2, if you shop around, is relatively cheap. In fact, I pay less per lb of
liquid food grade CO2 than I do for dry ice. Usually $1 per lb if you own your
own cylinder and find somewhere that has a pump and bulk tank to fill.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The systems will start at $5500 (16-20oz of plant, uses less
than $125 in CO2 to extract). If the extraction is to be done indoors, for
instance at a storefront, I will also provide lines to vent the CO2 outdoors.<br />

<div class="MsoNormal">
Tuesday, January 07, 2014 3:19 AM</div>
<div class="MsoNormal">
Due to all the inquiries about components of my system and
various items that I use to make my extractors, I am going to start carrying
some of these things.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The first will be some 316 Stainless Steel Canisters that
have Tri-clamp lids. I will carry 1,2,3, and 5L canisters. Why are these
different than sanitary spools? The canister is formed from a single plate of
metal, much like SCUBA tanks. Therefore they work well for moderate pressure
applications 200PSI and under.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The lids will all come equipped with two female NPT fittings
welded to them. 1-2L will have 1/4 FNPT and 3-5L will have 1/2 FNPT. The
fittings can be used to turn these into reclaim vessels, open butane
extractors, SCFE collection vessels when properly relieved, and many other
projects. If only one port is needed a threaded plug can be inserted to blank
one fitting.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
They use standard sanitary gaskets which I will carry in
nitrile mostly, as it makes a good material for most solvents.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
They will be available for sale in the next week or two.</div>

There are concerns, particularly in my at-home method about
the heat involved used to extract the essential oils and decomposition from exposure
to higher temperatures.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
I would like to address this. First, the extractions are
carried out typically at 85C (185F) and below. This is below the temperature
used for steam distillation. The extraction is happening in a very low oxygen
environment so there is a process call pyrolysis which is of most concern to
us. This is a process of irreversible thermal degradation, ie your terpenes,
oils, and waxes get ruined. There is undoubtedly some going on, however it does
not become substantial until temperatures above the boiling point of water
100C.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Further, the extractions are conducted at high pressures
which greatly increase the boiling point of your favorite compounds.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Considering the fact that it must be occurring on a small
scale even at my lower temperatures, it is best to limit extraction times to
1hr each when at 85C and ~4000PSI. If you wish to retain the most aromatic
compounds and you have alot of free time, conduct three or four extractions at
pressures of ~2500PSI for an hour per. Then three more at >4000PSI to collect
high molecular weight oils, and waxes. This way the more fragile oils avoid
pyrolysis.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
If you are extracting highly aromatic fragrances and
flavorings, like rosemary, lavender, jasmine, rose petals, you need not go
above 2500PSI as most of the lighter oils are miscible with liquid CO2.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
My methods are always changing, I strive to be flexible and
always up to date, so should you!<br />

Recently I had some time to build a pump driven reclaim
system for a customer. It uses a modified Appion pump and allows the extraction
and reclaiming to be done very cold. I float whichever container is being
compressed into in a bath of antifreeze, dry ice (made using liquid CO2 and the

<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The prototype is a 10L system with 316L stainless steel
extraction volumes. The most basic option is a design that is thermally driven,
or uses heat to move the CO2, as well as increase the pressure for extraction.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Using switches, the user can control the temperature of each
volume individually or both as a unit. By splitting the extraction into two
volumes this design becomes more time efficient. As the carbon dioxide is
expanded and the oils collected the solvent must condense somewhere else while
the extraction volume is heated and under pressure, in this case the solvent is
condensed in a chamber already filled with plant material so each movement of
the solvent is useful to the extraction.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The extractor design allows for easy transition to positive
displacement pumping of the carbon dioxide. So I offer two models, one that
uses temperature controlled fluid jackets (cheaper), and one that uses positive
displacement pumps (faster, more precise).</div>

I am reading the book Supercritical Fluid Extraction of
Nutraceuticals and Bioactive Compounds by Jose L. Martinez.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
It is going on about how carboxyl groups make the extraction
with only CO2 hard to achieve because they have polarity. It made me think about
a few things.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
This must be one reason why I can achieve moderate success
in small extractors because I use heat and am likely decarboxylating the oils
in the latter extractions.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Terpenes can be extracted easily at low pressures and with
liquid CO2 because the really aromatic ones are light hydrocarbons. In a
temperature driven system the best that can be hoped to achieved is low
pressure and low temp extraction of the terpenes, and subsequent extractions at
higher temperatures and pressures of mostly decarboxylated active compounds.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
In a pump driven system liquid CO2 can be moved to extract
the terpenes first, then a polar cosolvent introduced (like ethanol) to remove
the still acidic active compounds at low temperature. A pump system can do this
more easily because adding alcohol to make a solution with CO2 will lower the
overall vapor pressure of the solution and require either a larger mass of the
solution to exist in the same volume, or a much high temperature to achieve the
same pressures. Since the goal is collecting carboxylated oils, an increased
temperature is not desirable. Pumps make this more easily possible. If the
cosolvent extraction can be done at low temperatures <0F relatively little
chlorophyll will be picked up. If it must be done warmer the terpenes can be
separated at the beginning and the carboxylated oils can be cleaned with
activated carbon to remove the chlorophyll that is picked up with the alcohol.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The one gray area that I need to find specifics on is
exactly how high pressure environments of carbon dioxide affect the release of
the carboxyl group (more carbon dioxide). I would like to have control of
whether or not decarboxylation happens. A lot of processes call for
decarboxylation beforehand. The issue is this is done with heat in the cases I
have seen and will lead to loss of light aromatic terpenes.</div>

<div class="MsoNormal">
Hello everyone, thanks for keeping my blog fairly popular.
As I have mentioned before I am almost done with my first commercial system.
But I have not quit experimenting and learning</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Some of what I have learned to be the basics of carbon
dioxide extractions:</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
First you must extract, and especially collect at a range of
temperatures and pressures in order to have an extract that is diverse in its compounds.
Using a pump to conduct the entire operation at one pressure will produce
mediocre results. If the extraction is done at low pressure <2600PSI it will
be very aromatic but the yield is not as good. If it is done at high pressure
>2600PSI it will have better efficiency and yield but a less aromatic oil.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
If you can not have both good quality and quantity of yield
it would not really make much sense to switch from butane. After all SCFE is a
more involved process.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
In a temperature controlled system not utilizing pumps this
happens naturally. As you increase the pressure through heat a range is
experienced by the plant material. As the solution is released and collected
this happens again. This is a good reason to keep the collection as slow as
possible so the solution is collected at each position within the range for as
long as is sensible. What you end up with is an oil that has the properties of
an extract collected at all of the ranges versus the high selectivity of
keeping the solvent at an even pressure and temperature.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
This is possible to achieve with pumps which remove the
negatives of heating the plant, using some fancy electronic controls.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Another thing of importance is how the material is prepared.
As is the case with most commercial systems, the user wishes to run the plant
material moist without drying. This is why a lot of the extracts when first
removed are pretty much all liquid. This can be a result of bad CO2 as well
because the lower grades have higher allowable moisture contents. It is my
opinion that this hasty preparation is what causes the common leafy taste that
is associated with the large system's extracts.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Moral is: a range of pressure and temperature, and dry
starting material.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Having dry material also allows for the extraction to be
collected from the bottom of<span style="mso-spacerun: yes;"> </span>the
extraction chamber which makes it easier to collect oil from liquid CO2 as
opposed to supercritical. The labs intended the use of fractioning to allow wet
material to be run. It works but I have yet to hear a great review on the end
product.<br />

<div class="post-header">
</div>
<u>28 April 2013</u><br />
So I have some cautious yet exciting news. This week I will have my
parts for a simple extractor. It will be supercritical, and the plant
material will be immersed in the CO2 throughout the entire
pressurization. That means that there will be no selectivity via
pressure or temp but a more thorough extraction for those of us not
looking to throw away usable oils over a little extra wax and other
solubles. In a commercial extraction scenario it may make more sense to
give up a little oil vs clogging filters after ethanol winterizing. In
the home however, it does not make more sense because cleaning or
replacing filters ever so often is inexpensive and hassle free. When I
build it I will explain every thing about the extractor. I am also
sourcing parts to make solvent reclaiming systems.<br />
<br />
<u>01 May 2013</u><br />
All the parts are here and I plan on a test run tomorrow. Fingers X'd.<br />
<br />
<u>05 May 2013</u><br />
There was a hiccup in getting the CO2 tank filled, I ended up just
purchasing my own tank with a siphon tube....... Anyways this week it
will happen, I promise not to flake on this! Keep reading on and in a
couple of days you WILL see the end product of an at home CO2 extraction
at supercritical pressures and temps.<br />

I have passed the phase line pressure/temp for CO2 to go super critical.
I will let it rise to about 1300 psi before I maintain the temp that
gives me that. This is just to ensure that all of the CO2 goes into this
phase.<br />
<br />
Now, here is my safety spiel. The cylinders I use have an <u>operating</u> pressure
of 1800 psi, and a burst pressure minimum rating of 4500 psi. The
valves are outfitted with 3000 psi burst disks to ensure a controlled
depressurization long before the burst pressure. As well, the regulator
will depressurize if 3000 psi is reached. I am using a thermostat and
scientific heating pad to control the temperature. My method includes
filling the canister to 50% volume as opposed to the 68% volume they
are rated for. I am giving my self more head room for temperature and
pressure fluctuations.<br />
<br />
I will be continuously updating this post with details throughout the
night and the next couple of days as I winterize and purge whatever I
produce from these 57 grams of flowers.....<br />
<br />
Did I mention that I'm going to have a retail model ready by the end of this week? (tilts head slowly to the left and smiles)<br />
<br />
Full write-ups to follow.<br />
<br />
845pm<br />
<br />
So I decided to release the tiny bit of supercritical gas in my
regulator because well, I'm a weirdo. I let it sprinkle and condense on
the back of my hand my god I have never smelled such a sweet
aroma....... I'm going to let the extracts dissolve a little while
longer. According to the guys at <u>Skunkpharm</u> four hours should be
sufficient using supercritical CO2. Then, I'll cool off the cylinder and
allow the CO2 to condense so I can release it slowly as a liquid into a
pre-chilled glass jar. As always I strive for simplicity and the fewest
number of steps possible to achieve excellent results. TBC........<br />
<br />
<u>07 May 2013</u><br />
<br />
So you would probably like to see pictures of my early fruits.....<br />
<br />
<u>Update on photo below:</u><br />
Venting oils dissolved in CO2 into open air or even a vented jar is
impractical and likely to cause losses eventually. I no longer collect
oils this way. They are reclaimed with everclear after the CO2 is vented
as a gas from the collection tank leaving the residue behind.<br />

<Beginning to winterize.<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
</div>
Thoughts before bed:<br />
<br />
One more "rinse" of the cylinder with liquid CO2 tomorrow, because I am
certain there is more oil stuck to the walls. Reheating/pressurizing
should not be necessary.<br />
<br />
The smells during this extraction were sweet.<br />
<br />
Tweaking to the set-up as expected is necessary!<br />
<br />
Negative on the glass jar, only a solvent reclaiming system in the case
of CO2 is reliable because it keeps the solvent in its liquid phase, no
dry ice or oils clogging gas regulators and valves. There is a lot of
spurting that goes on if this is not addressed it seems.<br />
<br />
The system available at the end of this week will feature two cylinders:
a 20# liquid CO2 storage and transfer tank, a 20# extraction tank. Dual
safeties in the event of an over pressurization are in place, as well
as thermostat controlled heating. I will provide a safe <u>CO2</u> extraction system for a price that is competitive with the leading <u>hydrocarbon</u> extraction companies. <$2000 for a sixteen ounce system.<br />
<br />
<u>08 May 2013</u><br />
<br />
I conducted another rinse with liquid CO2 and evaporated it from the
tank leaving the oils behind to be picked up by ethanol for
winterization. I was much more able to reclaim my oils in this manner as
opposed to attempting to vent the CO2 into a jar. Silly me for every
trying it that way in the first place.<br />
<br />
Thank you for your patience and I look forward to the future! - JY<br />
<br />

I can not help but feel that the oil looks more appealing with each successive run.<br />

<div style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;">
More people these days are going back to nature as an alternative way
of healing diseases and health problems. Natural ways especially
aromatherapy are becoming popular as more people realize that you can
gain greater benefits by using natural and not synthetic remedies for
maladies. This trend paved the way for the creation of products like the
essential oils diffuser, which is gaining popularity worldwide.</div>
<br />
<b>What is an essential oils diffuser?</b><br />
This is a device used to spread essential oils in the air.<br />
Essential
oils diffusers can be used in the home, hospitals, hotels, health spas,
and even cars. Some diffusers use heat to diffuse and there are those
that use cold air.<br />
<br />
<b>What is the advantage of using a diffuser?</b><br />
A
diffuser helps to spread the essential oils in the air easily, quickly
and to a much larger distance. Essences found in the oil helps to keep
the air we breathe clean by killing viruses, bacteria, and microbes. It
also eliminates bad odor, molds, dust, mildew, and dust mites.<br />
<br />
<b> Where can you purchase a diffuser?</b><br />
You
can purchase a diffuser at any aromatherapy stores, at wholesalers or
health spas offering aromatherapy products. You can also visit relevant
websites and see if you like what they offer.<br />
<br />
<b>What exactly can be diffused?</b><br />
Usually
most liquids can be diffused readily but some thick liquids such as
sandalwood and patchouli may be hard to diffuse. If you are using a
diffuser that uses a nebulizer, avoid using patchouli and sandalwood as
these may clog it.<br />
<br />
<b> What is the best kind of diffuser?</b><br />
The
best kind of diffuser actually depends on your preference and needs.
However, in general, an electric diffuser is considered to be by and
large very safe, economical and convenient.<br />
<div style="overflow: hidden;">

<div id="article-content">
Essential oils diffusers can make a big difference in the way we
live our lives. Breathing in essential oils can change your mood, create
memories, and change the way you feel. They can also help with lung
problems, get rid of dust mites, mold, and viruses in the air. There are
many types of diffusers to choose from. Choosing one depends on the
size of the area you need one for and how much you are wanting to spend.
The best ones tend to cost a little more, but are usually worth it.<br />
<br />
The
best and most effective of all essential oils diffusers is the
nebulizer. A nebulizer breaks down the oil molecules into a fine mist
and then disperses it into the air. The mist is very concentrated and
the nebulizer really works well to spread the oil mist throughout a
room. One thing to keep in mind though, thick oils like sandalwood tend
to clog them, so be careful with the oils you use. They come in a couple
different shapes. One version is compact and another has a glass cone
with a oil reservoir.<br />
<br />
Our second place choice for essential oils
diffusers is the atomizer. The atomizer uses a fine mist of evaporated
water to disperse the oil into the air. This type of diffuser is easy to
use and works well. Just add water, oil drops, and plug in.<br />
<br />
And
in third place for essential oils diffusers is the fan diffuser. They
can be used for small or large rooms. Just choose the right model for
the size of the area. There are even ones available for your car. Some
use batteries and the larger ones need to be plugged in when in use. The
fan diffuser works by blowing cool air through a pad, that has absorbed
oil drops, and fills a room or area with the scent. These are easy to
use but sometimes the fan can be a little noisy.<br />
<br />
These are our top
3 essential oils diffusers to choose from. There are also candle
diffusers and lamp rings available, but heat has a negative effect on
the therapeutic benefits of the oil. They also can be a potential fire
hazard.<br />

Hello Everyone,<br />
<br />
I have finally replaced the EnJYN Scuba tank based system with a custom stainless steel vessel.<br />
<br />
<span style="font-size: large;">The Joe Blow</span><br />
<br />
These can be used to slowly flow through supercritical CO2 at up to
1800PSI, and the pressure vessels can be filled, sealed off, and heated
to achieve up to 4000PSI.<br />
<br />
I am only offering a 3oz size and an 8oz size to be used at home. Larger
capacities will only be offered in closed loop reclaiming systems.<br />
<br />
<u>The 3oz I am going to sell for $1199 and the 8oz for $1995</u><br />
<br />
<br />
<i>Finally, an added and unintentional bonus is that by removing the
quick connect from the hose and upper plug, cans of butane can be used
if desired. Both supercritical carbon dioxide extracts and butane
dissolved extracts can be made in this set-up without modification.</i><br />

</h3>
<div class="post-header">

These are proof runs of my stainless steel pass-through extractor, not
the retail version by any means. The collection vessel of course will be
a large diameter spool, I just can't seem to keep any when I have them
in stock.<br />
<br />
This new method and design is using one continuous extraction at
pressures of 1800PSI and below (Actually I capped it at 1500PSI). The
temperature and pressure ratings of the aluminum storage vessel are
never exceeded at any point.<br />
<br />
My stainless steel design allows for up to 3800PSI and so if desired it
can be sealed and heated much like the SCUBA tank. That is not the
intention, however. This system is meant for <u>convenience</u> for the small commercial market.<br />
<br />
I like to show the dirty along with the pretty, so here are some quick
and dirty videos of my new design of pressure vessels and a lavender
crumble extraction.<br />

<em><a href="http://en.wikipedia.org/wiki/Carbon_dioxide" title="Carbon dioxide">Carbon dioxide</a> usually behaves as a <a href="http://en.wikipedia.org/wiki/Gas" title="Gas">gas</a> in <a href="http://en.wikipedia.org/wiki/Air" title="Air">air</a> at <a href="http://en.wikipedia.org/wiki/Standard_conditions_for_temperature_and_pressure" title="Standard conditions for temperature and pressure">standard temperature and pressure</a> (STP), or as a <a href="http://en.wikipedia.org/wiki/Solid" title="Solid">solid</a> called <a href="http://en.wikipedia.org/wiki/Dry_ice" title="Dry ice">dry ice</a> when frozen.

<em>Supercritical CO<sub>2</sub> is becoming an important commercial and industrial <a href="http://en.wikipedia.org/wiki/Solvent" title="Solvent">solvent</a> due to its role in chemical <a href="http://en.wikipedia.org/wiki/Extraction_%28chemistry%29" title="Extraction (chemistry)">extraction</a> in addition to its low toxicity and environmental impact.

In addition, the solubility of many extracted compounds in CO<sub>2</sub> vary with pressure,<sup><a href="http://en.wikipedia.org/wiki/Supercritical_carbon_dioxide#cite_note-0">[1]</a></sup>permitting selective extractions.</em><br />
Soooo, in us’n layman’s terms, we use plain old CO2, that we have
gotten hotter than 31.1C/87.98F, while under at least 1086 pounds per
square inch pressure.<br />
In that state, the CO2 becomes a super solvent, which has higher
penetration power, and can be fine tuned to focus in on specific
constitutes, by varying the pressure, temperature, and by the use of
co-solvents like ethanol or hexane.<br />
Fair enough, and easy enough to accomplish several ways!
Traditionally a high pressure intensifier pump is used to achieve the
required pressures.<br />
Cryo-pumping also works. You start with liquid CO2 or dry ice and heat it in an enclosed space.<br />
My first conceptual of a system that was semi affordable, was a
simple minded system using liquid CO2 and heat to run it at about 1500
PSI. That eliminated the pumps normally used and by using a liquid
Dewar with a dip tube, with both a gas head and a liquid tap, the need
for any liquid pumps is eliminated as well.<br />
It is designed to use readily available Schedule 180 austenitic
stainless pipe and its largest component is small enough to fit in my 7″
X 36″ lathe. My original plan was to use an existing hydraulic
cylinder for my vessel, but alas, carbon steel embrittles excessively at
cryogenic temperatures.<br />
My design calls for achieving pressure by simply heating the pipe with available pipe band heaters.<br />
Pressure was controlled using a conventional, though expensive back
pressure regulator. Please note the attached conceptual, which reflects
my thinking four to five years ago. I put the project on the back
burner after reading the SFE CO2 patents for extracting cannabis, and
noting that CO2 isn’t a very aggressive solvent and the patented
processes used significant fluid exchange rates, as well as relatively
long spans of time.<br />
To compound that, reports from those testing SFE CO2 extractions
reported poor taste and effects, so I put CO2 extraction on the back
burner to just watch for awhile.<br />
Within the last couple of years several folks have done some
interesting work starting with dry ice. The first that I noted was able
to maintain high enough pressure in a test tube to keep dry ice from
sublimating as it warmed, so as to extract some Limonene from an orange
peel.<br />
That led me to question whether super critical pressures were
required to extract the essential oils from cannabis that we typically
extract with other solvents, and further experiments by others suggests
that it is not. Some even report better results at subcritical
pressures, especially with the use of co-solvents.<br />
Sub critical extraction presents an interesting twist from a
simplicity standpoint, so of course my simple mind immediately
envisioned replacing the test tube with a pressure vessel containing dry
ice in the bottom, and a basket of material suspended above it. Screw
down lid and bring it up to temperature with a pipe clamp heater for
pressure.<br />
Flooding is achieved by simply turning it upside down to soak the
material and right side up to drain. That step could be repeated back
and forth, to soak the material and keep the boundary layers diminished.
On setting it upright the final time, we could bleed off the liquid
into an expansion chamber and then to atmosphere, leaving behind the
oil.<br />
I have decided to build a 2″ X 24″ prototype, and have acquired two
resources on this project that emboldens me. One is the offer from a
dear old friend, to allow me the use of his aerospace pressure and
vacuum equipment manufacturing facilities for giggles and old times
sake.<br />
The other is an agreement with another old friend, who owns a
cryogenic equipment manufacturing plant back east and is familiar with
SFE.<br />
We have a mutual engineering support agreement in effect, in exchange
for my support on one of their projects with a former aerospace
customer of mine, who is now their customer as well.<br />
For my support interfacing their equipment with equipment of my own
design and manufacture before retirement, they will support me in
developing a simple minded DIY SFE system, that hopefully more of us’ns
can afford to build, or have built.<br />
<strong>So here is my first simple minded conceptual using liquid:</strong><br />
<a href="https://skunkpharmresearch.files.wordpress.com/2012/05/simple-minded-sfe-2-12.jpg"><img alt="" class="aligncenter size-full wp-image-1138" height="369" src="https://skunkpharmresearch.files.wordpress.com/2012/05/simple-minded-sfe-2-12.jpg?w=570&h=369" title="simple minded SFE-2-1" width="570" /></a><br />
<strong>Here is my simple minded conceptual starting with dry ice:</strong><br />
<strong>OOPs, solly</strong>, watch this space!<br />
After working all day on the drawing, my 2002 32 bit Auto Cad program
is not able to access my printer on my 64 bit processor, and I’m not
smart enough to figure it out, so I have to find a computer hero or
heroine first.<br />
The way my conceptual works, is the bottom of the cylinder is
filled with dry ice , on top of which sits a wire basket of plant
material. Clamp on band heaters turn the dry ice to liquid, which is
circulated and soaked through the material by simply turning the
cylinder upside down.<br />
After flipping it about a few times, over an extended soak, the
vessel is set upright and attached to the lower expansion chamber via a
hydraulic quick disconnect. The liquid is bled off, decompressed, and
the oil collected from the decompression vessel via the bottom drain
valve, as well as via the detachable bottom.<br />
<strong>Lu lu lu lu lu lu lu lu lu lu lu lu lu lu lu!!!!!!!!!!!!!!!!!!!!!!!! Progress!</strong><br />
Well thank the Great Spirit for ex-brother in laws, who can sort out
computer problems, so that I can print from virtual mode. Hee, hee,
hee, kept him at tossed the sister……….<br />
Here is my simple minded conceptual of how such a dry ice system
might work. More detail prints once I have exercised some resources.<br />
After further discussion with another experimenter, I have decided to
build the system to operate at 5000 psi and below. Instead of using
schedule 160 stainless pipe, I will gun grill a billet of stainless, but
will keep the bore at one inch.<br />

Hi ya’ll!<br />
Been out talking to folks running commercial CO2 SFE units and would
like to share some selected excerpts from their letters, to keep their
identities confidential:<br />
<strong><em>Hi Graywolf, here is some pics of the unit i have been
running for 8+ years. Our whole thing with this unit was to have maximum
fractionation capabilities.</em></strong><strong><em> </em></strong><br />
<strong><em>The extraction vessel is rated to 10,000psi, and made of stainless!!</em></strong><strong><em> </em></strong><br />
<strong><em>We use a basket to hold the material and I’m having a
natural cloth bag made that will go into the vessel and hopefully allow
me to extract 2x current volume.</em></strong><strong><em> </em></strong><br />
<strong><em>There are some great graphs around the net that show the
combinations of pressure and temps and the resulting density of co2. In
general high pressure (we go up to 10,000psi) works well in combination
with high temps (around 100c) and lower pressure around 5000 psi goes
well with about 60c.</em></strong><strong><em> </em></strong><br />
<strong><em>I tried high pressure and while i need to try again to
confirm, there seemed to be some degradation to the overall quality and
definitely the fragrance. the yield was higher and its much more
efficient requiring less co2.</em></strong><strong><em> </em></strong><br />
<strong><em>I already noticed on the bit of extract that i dissolved
in ethanol and then winterized and filtered, the flavor is no where near
what it was before going in the ethanol. I plan to try and get the
waxes out with only co2.</em></strong><strong><em> </em></strong><br />
<strong><em>I cant see any advantage to using either hexane or
ethanol or a mixture as a co solvent?? the compounds are easily soluble
in co2 and usually those types of things will help to extract more polar
compounds such as chlorophyll. It all depends on what your goals are?
maybe he is using that mixture to help fractionate out the waxes??</em></strong><strong><em> </em></strong><br />
<strong><em>I can do a small run next week using those co- solvents
and report back if i see anything magic or some beautiful separation.
maybe he is just some chemical engineer using a method that was used for
another project and he is trying to apply it there?</em></strong><strong><em> </em></strong><br />
<strong><em>It seems really counterproductive to use co solvents and
contaminate a great extract… maybe he can only do really low pressure
and he requires the co solvent to help the efficiency??</em></strong><strong><em> </em></strong><br />
<strong><em>I found material with a moisture content of around 10% to
be fine. I don’t know what the implications of a slight amount of
carbonic acid could mean? </em></strong><br />
<strong><em>I have heard it can make oils rancid, but have run
vegetable oils at 10+% moisture and had them test very low in peroxide
values in respect to oxidation and rancidity. I do not see any problems
with around 10% moisture, the water sometimes comes out with the extract
and is sitting on top and the few mls there can be poured off.</em></strong><br />

And from yet another hero!<br />
<em><strong>I. Extraction was performed by sub and supercritical CO2: </strong></em><br />
<em><strong> Subcritical (liquid): 10-12 ºC @ 65-70 bar for approximately 6 hrs. </strong></em><br />
<em><strong> Supercritical (liqid/gas): 40-45 ºC @ 230 bar for approximately 4 hrs. </strong></em><br />
<em><strong>II. Separation of fats and sugars, by winterization, chromatography and high speed centrifugation. </strong></em><br />
<em><strong>This part was very critical in the purification schema and required analysis of both the anaylate and precipitate. </strong></em><br />
<em><strong>III. Purification, at this point one has two options, Flash Chromatography or Wiped Film Evaporation (Short-path) </strong></em><br />
<em><strong>I performed both and in both techniques, one can obtain
purities in the range of 95-99% total THC (∆9, ∆8 and ∆6) with the
purity of ∆9 ranging anywhere from 78-98% depending on the parameters
set. </strong></em><br />
<em><strong>One last comment, probably the most important…..
absolutely no petroleum derived hydrocarbon solvent was used. Except for
the small amounts used for LC/MS analysis. This was my driving force
to see if it could actually be pulled off.</strong></em><br />

We are moving this project from research to active experimentation in
our FY 2013, now that the shack and Terpenators projects are a fait
accompli. What I did in FY 2012, was simply research and develop
resources.<br />
It was good that I did, as further research put things in better perspective.<br />
While I determined that my simple minded CO2 SCFE system would work,
it raises a the bigger germane question of why is this trip necessary,
given how effective BHO and some of the other extraction methods are.
Why spend the money for this more expensive fish trap, if we already
have the fish?<br />
The answer lies in that what CO2 SFE extraction shines at, is
selective extraction. By fine tuning the pressure and temperature, as
well as using co-solvents, specific components may be extracted, while
leaving behind everything else.<br />
That is of less value when discussing cannabis essential oil
extraction, in that it has been determined that it is the entourage
effects of all the terpenes present, including the diterpene
cannabinoids, that are responsible for its medicinal properties. That
however doesn’t mean that we can’t specifically focus on that list of
terpenes.<br />
The other thing that my research made clear, and that is using one
vessel to process the material and raise the pressure in, would result
in extractions along the entire temperature/pressure curve. Woops, no
selectivity there, but easily solved by bringing the liquid CO2 or dry
ice up to a higher temperature and pressure in a separate vessel, and
then equalizing it with the one containing the plant material! Easy,
but the system complexity grows.<br />
One of the interesting things that my research turned up during tete a
tetes with brothers owning and operating commercial CO2 SCFE’s, and
bumblers like myself whomping up DYI ghetto extraction equipment, is the
wide range of processes that different operators have achieved a
modicum of success at.<br />
One operator simply took the valve out of a CO2 bottle and filled it
with plant material and dry ice, before replacing the valve and heating
the tank to SCFE ranges. He then inverted the tank and vented the CO2
into a catch container, where it left cannabis essential oils behind.<br />
He claimed his best success using co-solvents at ~5500 psi and that
his product was superior to all competing, but alas, I was never able to
sample it and his spamming got him banned from the forums where we
shared information.<br />
Commercial SCFE operators report successful sub critical products as
low as 350psi, and another at 850psi, but I haven’t been able to sample
their successes, to confirm my own opinion of product quality. There in
lies the rub of course, as there is no common measurement and each
creator loves his creation.<br />
Fortune has ostensibly smiled on us however, in that two of the
operators that I have been conversing with, have agreed to work more
closely with us and to supply confirmation samples. Hee, hee,
hee……………………………<br />
<div class="MsoNormal">
<strong>Even simpler DIY SCFE C02 6-2-13</strong></div>
Hee, hee, hee, you have to admire simplicity. Here is the system by
jyndustriez which I mentioned, that simply puts the plant material in an
off the shelf CO2 tank, and floods it with liquid C02 from a second off
the shelf tank, before heating to achieve super critical state.<br />
<div class="MsoNormal">
More information on how he accomplishes that at <a href="http://jyndustriez.blogspot.com/" rel="nofollow">http://jyndustriez.blogspot.com/</a>, but here are some pictures he has shared:</div>

Progress! We got to play with a donated SCFE CO2
extraction sample and were able to heat it under vacuum and observe the
effects.</div>
<div class="MsoNormal">
As received, the sample was in a “wax” hydrate form, and was not aromatic. The flavor was mild, and the effects were good.</div>
<div class="MsoNormal">
As it was a small sample, I was unable to winterize
it to remove the waxes, but I was able to heat it to 115F, under
vacuum, and observe what happened.</div>
<div class="MsoNormal">
The sample out gassed significant CO2, even though
at 115F decarboxylation was minimal, and never quite turned clear, due
to the high wax content, but that isn’t unique, as BHO extracts are
improved by wax removal as well.</div>
<div class="MsoNormal">
On the surface however, the wax content seemed
high, compared to our typical BHO extraction, so I look forward to a
large enough sample to winterize and determine just how much.</div>
<div class="MsoNormal">
Here is a starting and ending photo, demonstrating the ending wax content.</div>

To add to our excitement, last week we got a guided tour of Eden Labs during our recent business trip to Seattle! What fun!!!</div>
<div class="MsoNormal">
Patrick, one of Eden Lab’s bright new sales
consultants, attended one of our BHO classes and subsequently invited us
for a tour, so how could we resist, hee, hee, hee, snicker, snark,
snort………………?</div>
<div class="MsoNormal">
Always a pleasure to see how the pros from Dover do things, and I do likes the way they detail a package.</div>
<div class="MsoNormal">
We lucked out in finding the original creator
available and got our guided tour from Fritz himself. Besides his
latest creation, we got to see not only his original test sled, but some
of the R&D that may make great strides someday, when Fritz can find
enough time to finish them, between current product demands……….</div>
<div class="MsoNormal">
Their latest all stainless creation was in final
assembly and testing, and was capable of extracting not only with
subcritical and Super critical C02, but also with refrigerants like
butane and propane.</div>
<div class="MsoNormal">
It was appointed well, and used pneumatic intensifiers both for the hydrocarbon pump, as well as the SCFE CO2 pump.</div>
<div class="MsoNormal">
It also sported a unique closure system, which
simply spins close and that greatly simplifies loading, as compared to a
12 bolt flange with a torque wrench.</div>
<div class="MsoNormal">
The vessel itself uses a Schedule 160 stainless
core, but adds water jackets, so as to permit the use of a commercial
heater/chiller for temperature control.</div>
<div class="MsoNormal">
The unit that we looked at, had a $60K base price,
plus the price of the hydrocarbon extraction capabilities. Not cheap,
and more complicated that most folks should attempt at home, but if you
need a machine capable of a quality extract, in commercial quantities,
you will need to step up to a system of this caliber, which includes
pumps to cycle the C02, and C02 recycle to recover it afterwards.</div>
<div class="MsoNormal">
Fritz did note that one of the things on his list
of thangs he is juggling, is a smaller lab sized unit, which fills the
market window for a smaller unit that doesn’t recycle. Looking forward
to see what comes up there!</div>
<div class="MsoNormal">
From a process perspective, Fritz shared that the
aromatic extractions are best done at low pressures and as the pressure
goes up, so does the rate of chlorophyll extraction. Based on his and
other input, I will focus on the range from 800 psi to 3500 psi. While
I’ve heard operating parameters up to 9500 psi, the lower ranges sound
more believable.</div>
<div class="MsoNormal">
As unbelievable as it may sound, ah think sometimes
operators shuck me, cause they are trying to protect process secrets
and lead me astray.</div>

Lu lu lu lu lu lu lu lu lu lu lu lu lu lu
lu!!!!!!!!!!!!!!!!!!!!!!!1 The Great Spirit smiled and JYNdustriez
loaned us a CO2 extraction setup and will show us how to use it, when he
visits to watch Dr. Fischedick’s lecture on 11-2.</div>
<div class="MsoNormal">
I’ve also located a local brother with an Eden Lab
machine, who is amenable to experimentation, so things are heating up in
the area of CO2 extraction at Skunk Pharm Research. We will have
machines from both ends of the price scale to experiment with.</div>
<div class="MsoNormal">
Sound CO2 has also extended us an invitation to
visit, and they run Apeks equipment, soooo even though our CO2 project
was slow getting in motion this year, it looks like it is finishing with
a bang.</div>
