Exactly. We manipulate the pressure to keep the butane liquid, and we manipulate the temp of the butane/cannabis solution to return the butane to gaseous state for recovery.

But you do not have to manipulate the temp its already being done by nature , just extract in an open container and then let it transfer back into a high pressure container . Why not ?
Seems like recovery of 'tane would be nil. Lots of solvent left behind unless they heat it all back up post flood/soak. Seems like a lot of trouble for very little benefit.
