The present invention relates to methods of separating one or more components from a feed composition, methods of desorbing one or more components from an absorbent fluid, as well as systems and apparatus that can carry out the methods. In one embodiment, the present invention provides a method of separating one or more components from a feed composition including contacting at least some of a first component of a feed composition including the first component with an absorbent fluid, to provide a contacted composition and a used absorbent fluid including at least some of the first component contacted with the absorbent fluid. In some embodiments the absorbent fluid can be an organosilicon fluid including an organosilicon including at least one of a hydroxy group, an ether group, an acrylate group, a methacrylate group, an acrylamide group, a methacrylamide group, and a polyether group. In some embodiments, during the contacting the feed composition can be contacted to a first side of a membrane while the absorbent fluid is contacted to a second side of the membrane. In some embodiments, the membrane can be a silicone membrane.

Method and apparatus for separating one or more components from a composition

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.
