ABSTRACT:
This invention relates to a sorptive contactor and more particularly to the process for separating, reacting or adding components of a fluid mixture. The process involves providing at least one sorption zone and at least one desorption zone. The adjacent ends of the sorption and desorption zones have aligned apertures through which strands of sorbent material may be passed. The space between the sorption and desorption zones is enclosed in an air lock. The separated strands will pass directly from the sorption zone to the desorption zone through the air lock, passing through the apertures without touching either housing. The surface tension of the liquid in the apertures and the slight overpressure in the air lock maintains the liquid in the sorption and desorption zones. The strands are maintained separate from one another throughout an endless loop so as to reduce the amount of friction on the strands. Each of the sorption and desorption zones has an open portion in its top through which the strands exit and/or enter, thereby eliminating the necessity of a mechanical seal of any type.
