Abstract:
A plant oil extraction system is disclosed utilizing a novel dual vapor recovery scheme and pressure differentials and valve timing conducive to continuous operation.

Claim (Index 1):
A distillation method, comprising:\n draining a solvent-oil mixture from a reaction chamber into a distillation column; distilling the solvent-oil mixture in the distillation column; triggering a dual vapor recovery process from the distillation column as a result of attaining a first pressure differential between the distillation column and any one of a plurality of solvent tanks; the dual vapor recovery process comprising:\n (a) opening a first vapor valve between the distillation column and a condenser; \n (b) opening a first solvent valve between the condenser and a first solvent tank meeting the first pressure differential; \n (c) using the first pressure differential to move vapor out of a headspace of the distillation column into the condenser without the use of a pump; \n (d) concurrently with (c):\n selectively activating the pump and opening a second vapor valve between the distillation column and a second solvent tank selectively, only if the pump is not already in use; \n pumping vapor from the headspace of the distillation column into the second solvent tank; \n \n (e) while (c) and (d) are underway:\n selectively opening a second solvent valve between the second solvent tank and the reaction chamber, once the pressure in the second solvent tank causes a second pressure differential sufficient to move solvent from the second solvent tank into the reaction chamber.
