Abstract : The design of a laboratory-scale pressure swing adsorption (PSA) system for air purification applications is described. Specific attention is provided to bed design, flow control, and feed generation systems. This apparatus is capable of automated, in-bed concentration, pressure and temperature measurements using computer control. Results are presented for some sample runs based on 150 SLPM of feed at three to four atmospheres of feed pressure....
