CO2 Subcritical Fluid Extractor Design - and other fun stuff

Hey folks

This thread must be read to this song to be truly understood:

[youtube]ebHfMRw--sE[/youtube]


Below is a design for a CO2 subcritical fluid extractor and a link to a thread in Jon Stewart’s forum I used to organize my thoughts. The SCFE can be assembled for less than $1000 or from used parts. I needed a quiet spot to empty my mind and I knew that no one would go to Jon Stewart’s forum looking for something funny except by accident.

The threads that you’ll be going to developed the way they are over two weeks, there was no preconceived plan, I originally just dumped the technical information and letters there then organized my mind for the next step. The challenge of designing a SCFE is something that I’m sure some of you can appreciate, there’s just nothing of value on the net - I thought the process though again and again and again until I could feel in the backs of my shoulders the physical properties of the gas change as it went through different temperatures and pressures in the system. Mostly Kali Mist.

The threads are designed around 9 posts, streams of information blended. There’s an array of ideas that I’m working on that are pretty much one in the same to me, so I had a stream of consciousness process to help me clear my mind, then organized the info. The streams are color coded - blue for technical, green for letters, herculanum font for Philisophicals, and so on. There is a disambiguator, on the second page - believe it or not that’s a real word.

Everything needed for the extractor is in blue, in the first two posts, you can just scroll through quickly or catch some of the humor on the way through. After dumping the technical info I realized that it would be too much for most people to absorb in one sitting, so I wanted to add other points of interest such as videos of The Trailer Park Boys and Kids In The Hall - two good Canadian shows that most people probably haven’t seen. I’ve got Philisophicals, mostly from the Greeks because I find their thinking to be so clean, some of my own when I got lazy. Mostly I just posted whatever shit I wanted then organized it so its logical in my mind. Now I can forget about it as I did the info in my threads on here. Dump truck mind.

I wanted to make a thread that had enough variety and quantity of fun stuff that people could go back again and again and again - because that is what will be needed to absorb the SCFE info. Most people will not get this the first time through, there’s a lot of fucking info even though I put it in point form. How do you grow 1 gram per watt as a first time grower? You don’t.

I’ve been obsessed with communication for the past month and a half, mostly through music but I started to look at holy carvings: the ancient Greeks found Egyptian hieroglyphs in temples so they were called ... . I had an idea that its important to communicate without words in some instances, taking an intellectual step out of the process and making the information more pressing on the brain. With my carvings I’m looking to make isomorphic squares, not quite a magic square (a 3 by 3 array of numbers where any column or row of 3 add to 15 is the common one know) - rows of 3 pictures that have an intuitive meaning when read left to right, and another meaning when read right to left. So, even though some of them are very pretty pictures they’re not just a bunch of pretty pictures lumped together: each row is a complete thought and the 9 picture array is a complete thought. Of course I’ll probably be the only one to get there because I have no legend for the pictures. In my third thread “Soul” there will be only a story written in holy carvings, and a legend explaining the context of each picture within ancient Greek mythology.

A lot of fucking with people, something I don’t do around here much. I would like help with two things, and only from people who would do them anyway:

1: Construct the SCFE

It should be relatively easy to slap together once a resin collector is built, like I say in the letter its got to be simple and plug and play. The do the process of failure testing and refining the process. I want to focus my thoughts on as few gifts as possible and the when I can get one off the table I can focus my thoughts on the residiuum.

2: Fuck with everyone I’ve fucked with in CoBerT Free World.

I’ve got characters listed with background info from the cartoon world. It’s something that I used for spill over, the process of designing the SCFE was taxing, then I used it to clear my head afterwards.

So, any type, quantity and quality of fucking with people that you folks would like to do I would appreciate it. Don’t feel constrained to only this and Jon’s site, but I’d like to keep all the SCFE discussion on Jon’s forum. So we have most of the fucking with people stuff in one spot, incase we get a visit.

I personally am a student of the Eddie Murphy school of fucking with people:



One last thing that’s important for anyone who wants to browse the thread - it’s formatted for a MacBook Pro 17” screen. Being obsessed with music (even though I play no instrument and can neither sing nor dance) I wanted to control tempo, dynamics, etc. By framing the text and images I make the story stop at certain spots, a lot of time moving down only one line or image block will change the perspective or show how characteristics are shared between two people listed, in other areas there are no frames for free flow at the readers pace. If you don’t have a MacBook scroll down to the holy carvings section (post 7, page ~90) to the only picture of the great wall of China, a blank page below Eddie Murphy explaining my philosophy of fucking with people. Shrink your screen to the blank space between Eddie and the Great Wall of China. The 3 nine image arrays should each fit into their own screen with no other image or text in the screen. You’re good to go. The music in these three carvings add depth, resonance, to the meaning.

Please add a post to this thread, to keep it at the top and so I know who’s visiting the Gift thread. As well, a post at Jon’s thread would be great if you have the time to register. And if you visit any other forums it’d be great if you could copy and paste this info there as well, I’d like to get the whole community involved in developing the CO2 extractor.

Holy Carving

Procedure

1: Fill the extraction tube and attach it to the extractor.

2: Heat the CO2 tank to 100 F and hook it up to the extractor, opening the valve to the temperature gauge and wait until the temperature gets to the subcritical range.

3: Open the valve between the Pressure Regulators slowly, until the Pressure Gauge in the Extraction Tube section is the same as the setting on the first Pressure Regulator.

4: Open the valve to the Resin Harvester and run the extraction until the pressure in the Harvester is the same as the pressure on the first regulator, before the Extraction Tube. Or until the operator feels that all of the resin has been extracted from the plant mater. Check the temperature gauge after the extraction tube to be sure the CO2 is still in subcritical range, some gas may have to be run through that section to bring it to temperature critical (Tc).

6: Close all of the valves and bleed off the pressure in all of the tubes. All of the tubes, gauges and valves should already have been cleaned by the subcritical CO2.

7: Cool the Resin Harvester in ice water to take the CO2’s temperature and pressure out of subcritical range. Cooling can be used if subcritical pressure is reached in the harvester before a larger extraction is finished.

8: Bleed off half of the pressure in the Resin Harvester to another tank to reduce the pressure and chance of loosing resin when venting the CO2. If a person wanted to set up a string of tanks they can take two scuba tanks, cut them in half and thread the top half of one as female and the top half of the other as male, making a two valve resin harvester. Stainless steel pipes with a valve fittings for each cap makes an excellent series of harvesters. A string of a half dozen double ended tanks could be set up for bleeding and venting for larger operations.

9: Use a vise and strap wrench to unscrew the two halves of your Resin Harvester & harvest your resin.

"one question: is using the pvc necessary"

LOL!! Good point!

The model is a conceptual - its a teaching model only, not a working model. That's made from stainless steel - all of the written: parts list, assembly instructions, operating directions and parts list are in BLUE text on Jon's forum.

Everything else you advanced is correct, and more. There are very few trace chemicals left after a butane extraction, the concern is more for impurities in the butane than actual butane itself. But ... emptying two cans of butane into a single tray of brownies makes me queasy. Butane leaches various heavy metals from PVC, there is a past about that on my "gifts" thread on Jon's forum.

NL if you could would you open an account on Jon's forum and copy and past the question there - I want to start a discussion ... with other people for awhile!

Sometimes the journey is more important than the destination - I'm sure I could have made money selling these by now but if I start giving away fishes we're not going to go where we have to go. In pleasure boating there are two basic schools of thought - sailing and stink pots. In a power boat the destination is important - if going to an island a few clicks off shore you can power out in minutes and everyone can go about doing what they want to do. Sailing out requires time, skill and effort - people can get a ride out to the island and enjoy the scenery or they can chip in and help sail the boats: learning new skills that they can pass on, developing working friendships with their crew mates.

We are rudderless with only one engine working on a side, spinning us in circles.

A CO2 extractor is pretty much an expresso machine - at 580 PSI, and CO2 instead of water.

.

The white round dials are for temperature, we need 88 F at the extraction tube

The black dials are for Pressure - we need 580 psi for the CO2 at the extraction tube but will start at 3000 psi and end below 580 psi


What do those two lines mean?

1: You need hot water to make expresso.

2: We have to pour the water from above because it won't flow up.

3: Set the dials to the numbers on the model and you're ready to go.


The gauges, regulators, stainless steel tubes, CO2 tank are all right off the shelf; the resin collector any tank that can be opened. Plug and play.

We're just not use to dealing with pressure in our daily lives and thinking of a gas as a solvent. Think of it as a liquid under pressure like a garden hose, it is a fluid, similar properties. Scuba divers might be more familiar with pressure.

.

The square grey boxes are pressure regulators - nothing more than a set of locks at the Panama canal. High pressure input on one side, low pressure comes out the other side? How? The same way the wiring in your car works - it doesn't matter, you can drive to the beach without knowing about electricity.

.

Pipes, tanks, regulators and gauges. Simple. Screw them all together and pack your extraction tube.

All we are doing is running a solvent through plant matter, exactly the same as pouring hot water though coffee. The pressure differential between the high pressure CO2 tank and the low pressure resin collector acts as our gravity to force the solvent through the plant matter.

"looking forward to seeing it working"


Putting vids of mine on the web will do us absolutely no good, we'll just continue spinning in circles. Sometimes the process is more important than the product.

is pvc/cpvc really safe to use for something like this?
I read where you can buy centrifuge's of plastic and do this on a much smaller scale.. But I'm pretty sure those centrifuges are a one time use.

It's a lot of info, even in the summaries.

I hope to have an assembly and operation video of a working extractor online tonight or tomorrow night - I didn't want to do it this way but you guys drove me to it. I'm having more trouble figuring out how to record a video and put it online than I did designing a wacky CO2 working extractor from shit I've got lying around the house.

Presentation is everything to me of course.

Hi, I was us looking for extractor plans when I saw this forum. I am a Machinist for 30yrs now, and just thought I would mention pipe threads that you use for assembly. I am sure you have heard of NPT threads used on pipe. Regular NPT is ok for low pressure but you need to use NPTF threads for high pressure, NPTF are what they call a dryseal thread, There is a slight difference in the threads, Npt will leak and you need a sealer, that under pressure will leak, NPTF are designed to crush together when assembled making a dryseal, and a mechanical fit, so it will hold up under pressure.

One other thing I do not see a pressure relief valve in your design? you may want to add one in, in case things get away from you pressure wise... better to blow off then blow up.

idk about all of you. but when I see a high pressure system like that I get spooked. some thing waiting to blow up in your face.
