Abstract
Construction and operational costs of simulated moving bed adsorptive separation process units are reduced by recovering desorbent from both the extract and raffinate streams of the process in a single column. Both streams are fractionated to recover desorbent, which is removed at one end of a dividing wall column, while separate extract and raffinate products are removed from the other end of the column.
