Method of removing volatile compounds from emulsions

A method of separating a volatile compound from a liquid feed mixture comprising an emulsion, the method comprising:

• contacting a first side of a first membrane with the liquid feed mixture comprising the emulsion having a polymer and the volatile compound wherein the polymer is an organopolysiloxane polymer, the volatile compound is a volatile siloxane or both;
• and
• contacting a second side of the first membrane with a sweep medium comprising a sweep liquid which comprises at least one of an organosiloxane, an organopolysiloxane, and organosilane, to produce a permeate mixture on the second side of the first membrane and a retentate mixture comprising the emulsion on the first side of the first membrane, wherein the permeate mixture is enriched in the volatile siloxane, and the retentate mixture is depleted in the volatile siloxane.

A method of separating a volatile compound from a liquid feed mixture comprising an emulsion, the method comprising:

• contacting a first side of a first membrane with a liquid feed mixture comprising an emulsion having a polymer, and at least one volatile compound, wherein the volatile compound comprises a volatile organic compound, a volatile inorganic compound, a volatile siloxane, a volatile linear siloxane, and/or a volatile cyclosiloxane, the first membrane comprises a dense silicone membrane having a thickness of about 1 μm to about 300 μm, and the emulsion has a temperature of about 20° C. to about 120° C.;
• and
• contacting a second side of the membrane with a sweep medium comprising a sweep liquid, wherein the sweep liquid comprises an organosilicon liquid, to produce a permeate mixture on the second side of the first membrane and a retentate mixture comprising the emulsion on the first side of the membrane, wherein the permeate mixture is enriched in the volatile compound, and the retentate mixture is depleted in the volatile compound by 1 wt % to about 99.99 wt %, as compared to the liquid feed mixture.
