SYSTEM AND PROCESS FOR RECOVERING PRODUCTS USING SIMULATED-MOVING-BED ADSORPTION

摘要

A process according to various approach includes flushing residual fluid within an intermediate transfer line of a purification zone defined as a region of the adsorptive separation chamber between the feed stream transfer line and the extract stream transfer line away from the adsorptive separation chamber to remove at least a portion of the residual fluid from the intermediate transfer line. The process may include directing the residual fluid flushed from the intermediate transfer line to another transfer line that is not a transfer line of the purification zone to restrict the residual fluid from being introduced into the purification zone.
