Argon purification process

摘要

A pressure swing process and system for purifying a first gas, preferably argon, from a crude feed gas stream containing the first gas and second gas(es) utilizes two adsorption beds and continuously promotes the crude feed gas to the bed during the process and simultaneous equalization of pressure in the two beds in top-top-top end and bottom-to-bottom end equalizations in each bed following purging of each bed.
