New developments in pressure swing adsorption. Continuing development of the adsorption agents and optimization of the process have permitted solution of new problems of selective separation and isolation of gases from gas mixtures and of gas purification by pressure swing adsorption. While processes have previously been developed in which the product gas is obtained during the adsorption step, more and more processes are now becoming available in which gases of high purity are obtained during the desorption step. After derivation of the fundamental desorption steps, the new techniques are illustrated in the case of the enrichment of CH 4 , CO 2 , and ozone, and for recovery of NO x from nitric acid waste gases.
