That looks really good. Enjoyed seeing the wrench still on the table. Reminded of walking by the Physics building and their offices full or electronics and tools around, to build their equipment.

So it will extract what, some substance out of a solution?

@design_RG

usually to allow you to extract from solids (plants usually) with some solvent that would boild at 1ATM but would be liquid between 1atm and 15 atm... so basically butane extractions which will hover at about 2 - 3 atm

Very interesting! I had seen mentions of using Buthane for extracting THC and CBD oils from non-flower parts of cannabis plants. Clippings, leaves, etc.

That apparently can generate significant returns, people growing hemp for example, which has no thc but some cbd.

@Karthikdeva

@design_RG

Yea same setup you would use for that. In fact youd probably want to do whole plant extraction if you could, thats how they make a lot of the extracts in california.

But pretty much good for exacting any sort of plant oils

@Karthikdeva

@freemo Interesting.

So, you would use Buthane as a solvent, then pressurize it to the range where it's liquid, heat it to boil off the oils and then cool the vapours, like a distiller, right?

Would the buthane stay behind in the boil pot?

@design_RG

No heating needed.. You fill the top chamber with plant and butane then seal all the valves. it will boil but be ice cold until the pressure reaches 2 - 3 atm. At this point it should be about room temperatue and a liquid under pressure (just like it is when you see it in a lighter).

After it soaks for some time you open up the middle valve. There is a screen in there so now all the liquid goes into the bottom container and the plant stays in the top.

Then you open the valve that lets the gas escape to the outside. At this point gas will start rushing out as the pressume normalizes back down to 1atm. As this happens it will start boiling again and the pressure will drop from 20C room temperature down to around 0C and get ice cold. It will continue to boil at this temperature till all the gas is gone. You will then be left with the essential oils

@Karthikdeva

@freemo Oh, amazing!

The gas is totally vented and lost, everytime then? Nice to learn something new, TY.
@Karthikdeva

@design_RG

Do9esnt need to be, but to recapture it as liquid you need some dry ice (or a heat source but not a good idea around butane)

@Karthikdeva

@design_RG

Essential oils not suitable for steam extraction is the bulk of it.
