✦ Synopsis

Abstraet--A variant of the pressure-swing adsorption cycle is described in which the fluid flows and pressure variations are produced by pistons moving in cylinders at either end of an adsorbent bed. To model such a cycle, pressure variations cannot be taken as a boundary condition, but must be calculated from the prescribed volume variations and gas dynamics. A numerical model has been developed capable of predicting these pressure variations, and the consequent performance of the apparatus. The model allows for time-varying pressure and varying superficial velocity along the bed. The model has been used to simulate air separation on a zeolite bed, and good agreement with experimental results has been demonstrated. The effect of varying design parameters is investigated, g~ 1997 Elsevier Science Ltd

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 collo
