Title: Dynamic film separation method having improved selectivity
Inventor: MAAKU EI RAPATSUKU
IPC: B01D61/36
Filed: 1990-12-21
Abstract: PURPOSE: To maximize the separation of one membrane permeable component in a multicomponent fluid mixture from another by introducing a feed mixture to the first face of a membrane so that the first and the second component begin to come close to a steady- state membrane permeation, and by collecting a mixture which is rich in the first component from the second face of the membrane during a predetermined period of time which begins prior to the time when the second component reaches a steady-state membrane permeation. CONSTITUTION: A feed flow (150) containing at least two kinds of membrane-permeable components is introduced to the first face (14) of a membrane (12) through a switching valve (18). The first permeable component, in this case, declinates from a steady-state permeation in a higher speed than the second permeable component. A permeated liquid which is rich in the first component is collected from the second face (16) of the permeating membrane (12) through a converting valve (20) and the feed flow is allowed to contact with membrane (12). After a predetermined period of time has passed (the time necessary for second permeable component reaches to a steady-state of the membrane (12)), the switching valve (18) is rearranged to discontinue the introduction of the feed flow (15) to a membrane module (10).  It becomes possible, by this way, to produce a permeated substance made selectively richer in one permeable component over the other from a multi-component feed mixture.
