ABSTRACT:
A continuous process for separating charged components of a fluid mixture is disclosed which comprises forming a sorption zone and a desorption zone, said sorption and desorption zones being separated by a boundary of a sorbent material which continuously moves back and forth between the sorption and desorption zones, causing a fluid mixture to flow into the sorption zone wherein an electrical potential is imposed to promote sorption of one of the charged components of the mixture by the sorbent material, and imposing an electrical potential in the desorption zone such that the sorbed component will be desorbed when the sorbent material containing the sorbed component moves into the desorption zone. This sorption separation process may be used in a network (including a linear series) of sorption/desorption units for separation of multiple components of fluid mixture or for more complete separation of one component of a fluid mixture.
