Just wondering how much more expensive it would be to run an oxygen or co2 setup and how much more potent/clean the oil would be from these means than the butane method....and if it is reasonably inexpensive how to do it?
butane is a smaller yielder than co2. I recieved 10lbs from a pre rinsed bho batch. It was claimed 10% had been removed prior w butane. So IU loaded up my vessel w a qp and proceeded to go w a co2 extraction where I was able to recover 6 grams from that. that avereges out to about 1.25 grams per ounce. So if there estimate was right, they had obtained 2.8 grams per oz, and thats where I stepped in and added to that yield which made it 4.05 grams recovered from one oz. wow thats amazing.
you can manipulate the pressure temp variance w subcritical as well as supercritiucal, its the same beast we are playing w that has this low critical temperature of 88F. so keep it below that and you have a subcritical extraction, right? wrong. once the valve is cracked, the temperature drops as the pressure is lost. any liquid or scf at the point of releasing pressure will revert back into dry ice inside the vessel. now w the valve cracked as your extracting, now is the time to check your temperature. thats why most extractions are sub rather than super. bringing it up to pressure then bleeding off isnt a scf extraction. it must extract @ the targeted area to qualify as such. But once people start getting their hands dirty and start putting in work, will all these opinions be determined fact or fiction. I already know, you guys are the ones left guessing. who the hell keeps spreading ill advised whipping techniques that at best may add the additional weight of air in the extracts?
trash in the yields or ballast isnt something I account for yield. There's only a couple areas of interest to me, the cannabinoid fraction and complete removal of delta 9 as the main desired compound of interest. So in actuality the theoretical yield isnt this great big yielding number of 30-40% . When the only thing considered is how much active ingredient was recovered, is where co2 comes through. Can turn a matrix into placebo. I have confidence that Graywolf is supercompitant in his ability to purge out the last bit of tane in their, but I dont have that same opinion about everybodies bho. Ive seen some of these proceedures and there far from acceptable. So dont worry about your abilities, worry about whomever is putting stuff out there thats heavily residued, under purged, and unfit to be in my body.
gray, let me explain my simple scfe schematic. see the picture to the left in my avatar. one large 6k psi vessel will be brought up to temp and pressure, and when 6k is reached, a lever valve surges into an awaiting 10k vessel. once the two reach an equalibrium, which is very quick, i lock the vessels back up and focus on heating the vessel @ 10k, only limiting it to 65C. thats how i can get away w out the use of pumps saving a ton in liquid co2 costs. My batches are relatively small, about 1/4lbs weed, 10lbs co2 costing about $15 to yield anywhere from 6-12 grams. those arent the most impressive numbers, but they real.
