CO2 Extraction

Post by Dick Fein »

A CO2 extraction method is also known as Supercritical Fluid Extraction and uses carbon dioxide, in the liquid form, as the solvent. Like BHO, CO2 is used to strip out different elements in the cannabis plant to create pure hash oil. Additionally, CO2 is used for cannabis concentrates.

CO2 is the gas we breathe through our lungs and essential food for plants. This is why the oils extracted are,
in essence, a “safe liquid solvent.” When a specific amount of pressure is applied to CO2, the gas becomes a liquid. In the case of cannabis extraction, the solvent is pushed through the plant material at such a high pressure separating the plant from the purest essence of the cannabis. The result is transparent amber oil.

Other popular products produced by the CO2 method are decaffeinated coffee, hops for beer and pharmaceutical precursors.

I don't know what the aparatus looks like, that will be the experimental part.
But when I ran co2 I just bought a tank and I think it cost me $20.00 to fill it.
I told them it was for my draft beer.
If you can eliminate the risk of explosion and reduce the cost of your solvent to almost zero, then the sky is the limit.
Unlike butane you should be able to recover 100% of the co2.

ok,
the reason this isnt seen is that for co2 to remain a liquid it has be under over 1700 psi...
compared to butane at 8 bars or roughly 350 psi

the aparatus which will hold it fluid long enough to work has to withstand 5 times greater pressure that the opne in which butane will work
