ABSTRACT:
There is disclosed a multiple-effect evaporation system wherein the last effect of the system in the direction of miscella flow is provided with a stripping tower in which vapor effluent from that effect countercurrently contacts feed to that effect. In application to the recovery of solvent from miscella obtained by the extraction of defatted seed material with an aqueous organic carbohydrate-selective solvent, pressure in the evaporation zone of one of the effects is maintained at atmospheric. Additionally, at least one of the effects other than said last effect may be provided with a rectification column.
