A simplitied dynamic model for a PSA air separation process is developed based on linearized mass transfer rate expressions and binary Langmuir equilibrium. Constant pressure is assumed during adsorption and desorption steps but the variation in flow rate through the column due to adsorption is aeeo
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 calc
The performance of various metal ion-exchanged A-type zeolites and metal-incorporated A-type zeolites for Oz and Nz adsorption was studied to provide a pressure swing adsorption (PSA) process. Metal-incorporated A-type zeolites adsorbed N2 in larger quantities than metal ion-exchanged A-type zeolite
Pressure swing adsorption cycles for the production of oxygen from air have been analysed for equilibrium separations, using the method of exergy analysis. The optimum operating point has been determined and individual component losses identified. A modified cycle incorporating a pressure equalisati
