Modeling and Simulation for Pressure Swing Adsorption System for Hydrogen Purification
Electrical Engineering Journal: Despite tremendous growth in practical applications of this technology, the design of PSA system is more of an experimental basis. The realistic model of a PSA cycle consists of flow rate which varies due to significant adsorption, while the heat effect needs also to be considered due to adiabatic thermal conditions. In this paper, an effort has been made to model and simulate a PSA cycle for hydrogen purification. For this purpose, a system consisting of 4 beds and 8 stages was considered using beds of activated carbon and zeolite. The PSA process for hydrogen purification uti-lizes different loading capacities of adsorbent at different pressures to separate a gas mixture into its components. The loading capacity of an adsorbent is the amount of gas that can be bound by mass unit of the adsorbent material. The extent to which an adsorbent can be loaded increases in general with the partial pressure of the gas component.
