ABSTRACT:
A continuous process for contacting components of a fluid mixture is described wherein at least one sorption zone is formed in a first separator. A sorbent material, which is in a continuous solid form, is passed through the sorption zone and then passed outwardly from the sorption zone. In the preferred process, a plurality of sorption zones are provided in the separator and a plurality of endless belts of sorbent material are passed through the sorption zones. The sorbent material is preferably a reversibly swellable material which swells as a result of contact with fluid in either the sorption or desorption zones and from which the nonsorbed fluid can be expressed during passage through the compression seal at the zone boundary.
