ABSTRACT:
Drycleaning fluid is recovered from spent drycleaning fluid filter elements by passing steam through the elements to form a steam/drycleaning-fluid vapor mixture. The mixture is condensed into liquid state and the two constitutents are separated. The apparatus includes a condensing chamber and a separating chamber with a novel valve for ensuring that drycleaning-fluid vapors do not escape into the work area.
