(under subclass 800) Subject matter wherein a liquid hydrocarbon is recovered from a liquid mixture containing the hydrocarbon by the use of a solid apparatus member having one of the following features: (a) is a thin member which permits the passage of molecules or ions having a certain size or shape while excluding molecules or ions having a larger size or bulkier shape; (b) is a porous member which because of its composition permits the passage of a certain type of molecule, e.g., a polar molecule, while preventing the passage of molecules of incompatible type, or (c) is a member which because of its composition causes finely divided liquid material dispersed in another liquid to form larger drops.
