PRESSURE SWING ADSORPTION TECHNOLOGY FOR HYDROGEN PURIFICATION-A STATUS REVIEW
Pressure Swing Adsorption (PSA) processes are designed for production of hydrogen or ammonia synthesis gas from steam methane reformer off gas with or without by-product carbon dioxide, as well as for production of H2 from refinery off gases. A variety of adsorbents are used for these processes. The ease of desorption often dictates the adsorbent selection. Empirical PSA process performance data are used to fine- tune mathematical design models. The hydrogen productivity of the PSA process can be increased by rapid PSA process cycles. The hydrogen recovery can be increased by hybridization of the PSA unit with adsorbent membranes. Novel sorption enhanced reaction processes, based on the principles of PSA, can be designed for production of hydrogen by low temperature steam-methane refining.
