A numerical simulation has been developed for a simple two‐bed PSA system in which kinetic effects and changes in flow rate due to adsorption are significant. The model is therefore more general than most previous models for the PSA cycle. The model equations are solved by the method of double collocation. When applied to air separation on a carbon molecular sieve, using independently measured kinetic and equilibrium parameters, the predicted performance appears consistent with available performance data for a commercial unit.
