ABSTRACT:
Polyurethane foams are employed to separate vapor of a volatile, organic liquid such as perchloroethylene from air or other gas containing the organic vapor. The absorbed, organic vapor can subsequently be recovered in liquid form by desorbing the vapor from the vapor laden foam and subsequently condensing the desorbed vapors.
