Abstract
A solvent separator apparatus having a vertical accumulator tank with a top end and a bottom end, the accumulator tank being serially connected to a vertical reservoir tank having a top end and a bottom end; a down tube vertically positioned in the accumulator tank having a top end nearest the top end of the accumulator tank and a bottom end nearest the bottom end of the accumulator tank, with an inlet at the top end of the down tube and an outlet at the bottom end of the down tube; an inlet conduit connected to the inlet of the down tube, the inlet conduit entering the bottom end of the accumulator tank and defining an upward flow path within the accumulator tank to the inlet at the top end of the down tube; a heat exchanger in communication with the down tube for withdrawing heat therefrom; and a transfer conduit defining a downward flow path from the top end of the accumulator tank to the bottom end of the reservoir tank. Systems in which the apparatus is combined with a dry cleaning machine are also disclosed.
