Abstract
The invention maintains a nearly constant cycle pressure ratio along with a balancing of the adsorbent vessel effluents in a pressure swing adsorption process. The invention monitors cycle pressure ratio and subsequently alters the cycle step times and flows to sustain its value, thereby maximizing plant performance and avoiding unnecessary shutdowns. Maintaining a nearly constant pressure ratio assures that the plant production is optimized and that power consumption is minimized. The balancing of the adsorbent vessel effluents, using the corresponding waste purities, is used to further improve plant production.
