PRESSURE SWING ADSORPTION PROCESS WITH REDUCED PRESSURE EQUALIZATION TIME

摘要

A method to reduce the cycle time in a pressure swing adsorption process by reducing the required pressure equalization time in a cycle, thereby reducin g the overall cycle time and increasing product recovery per unit of adsorbent used. This reduces the amount of adsorbent required in the beds for a given feed rate while continuing to provide product at an acceptable product purity, and has the desirable effec t of reducing the capital cost of the process equipment required for a given volumetric production rate.
