Abstract
The present invention relates to a method of removing a gas from a mixture. The method includes contacting a silicone membrane with a feed mixture including at least a first gas component and contacting a second side of the membrane with an organosilicon sweep liquid, producing a retentate mixture depleted in the first gas component and an organosilicon sweep liquid enriched in the first gas component. The invention also provides methods of removing a gas from a liquid, and methods of regenerating and recycling an organosilicon sweep liquid.
