Abstract

Organosilicon compounds in a process exhaust stream from silicone production are removed by contacting the exhaust stream with a semipermeable silicone membrane which is selectively permeable to organosilicon compounds and oxygen relative to nitrogen. The pressure on the permeate side of the membrane is preferably less than the pressure on the retentate side.
