Compressed air and gas purification and fractionation for high purity applications by improved PSA processes
An objective of this paper is to review the purity requirements for clean air and gases used in industrial and laboratory applications. Also described are the principles applied in the design of regenerative pressure swing adsorption systems to meet the most recent process requirements. Methods developed to reduce the energy consumption of the pressure swing process are described.
