A vaporizable solute transfer system for transferring a vaporizable solute from a gas feed mixture to an absorbent liquid comprises an absorption module, a porous membrane which divides the absorption module into a gas-feed chamber and an absorbent chamber, a regeneration module, and a nonporous material which divides the regeneration module into an absorbent chamber and a vacuum atmosphere chamber. The absorption module has gas feed mixture inlet and outlet ports which communicate with the gas feed chamber, and absorbent liquid inlet and outlet ports which communicate with the absorbent chamber. The regeneration module has a liquid absorbent inlet and outlet port which communicate with the liquid absorbent chamber, and a vacuum outlet port which communicates with the vacuum chamber.

A vaporizable solute transfer system for transferring a vaporizable solute from an aqueous feed solution to an extractant liquid comprises a fluid tight housing, a porous membrane which divides the housing into a feed solution chamber and an extractant chamber, and a vacuum atmosphere chamber formed of a nonporous material. The housing has feed solution inlet and outlet ports which communicate with the feed solution chamber, an extraction inlet port which communicates with the extractant chamber, and a vacuum outlet port which communicates with the vacuum atmosphere chamber. The vaporizable solute transfer system also includes a pressure difference control means for maintaining a difference between a liquid pressure of a feed solution chamber and a liquid pressure of an extractant liquid in the extractant chamber substantially within a predetermined pressure range so that an interface between the feed solution and the extractant is substantially immobilized at the membrane. The vaporizable solute transfer system is particularly adapted for transferring vaporizable solute from a feed solution to an extractant, which feed solution and extractant may be immiscible with one another when in direct contact.
