A Simple Equalization Pressure Prediction Method for Pressure Equalization via Tanks in PSA Process

Abstract

Pressure equalization is one of the key steps that is being used in Pressure Swing Adsorption (PSA) processes, recently. Usage of empty tanks for pressure equalization steps is also getting more attraction due to advantages of energy saving during pressurization and to eliminate unfunctional Idle steps. Equalization pressure prediction is also very crucial for the PSA simulation. Inaccurate estimation of equalization pressure may result in deviations of gathering the real process performances. This study proposes a simple method for estimation of equalization pressure based on simple material balance on tank equalization.
