Membrane separation involving a two-phase fluid on membrane side

摘要

There is provided a method of transferring at least one substance across a membrane (6) from a first fluid to a second fluid, wherein transfer of the substance from the first fluid to the second fluid occurs across the membrane (6); wherein the membrane (6) comprises a non-porous membrane; and wherein either the first fluid or the second fluid is a two-phase fluid (1) which comprises at least two fluid phases (12, 13) and wherein the other of the first fluid or the second fluid is a one-phase fluid (5) which comprises at least one fluid phase.
