Abstract
A membrane contactor for separating components from a feed gas stream comprises a housing, a feed gas inlet for receiving the feed gas stream at a first pressure, and a liquid inlet or receiving a stream of liquid at a second pressure, the liquid containing an absorbent for reacting components of the gas stream and a slip gas outlet. The contactor also includes a plurality of fibers with pore channels in contact with the feed gas incoming from the gas inlet on a first side, and in contact with liquid incoming from the liquid inlet on a second side, producing a gas-liquid interface at the pore channels. Liquid is prevented from wetting the pore channels by maintaining the first pressure of the gas stream higher than the liquid stream, and a portion of the gas stream bubbles through as slip gas into the liquid stream due to the elevated pressure.
