Abstract

By model simulation, the effects of bed pressure drop (ΔP) are examined for three adsorber processes: constant-pressure adsorption, multibed PSA, and single-bed rapid PSA (RPSA). RPSA relies on ΔP for separation. Air/5A zeolite is used as the model system. ΔP gives rise to early breakthrough in constant-pressure adsorption. For multibed PSA cycles, the net effect of ΔP is to increase the light product purity (O₂) but decrease its recovery. The model for RPSA is capable of predicting its separation performance, as verified by agreements with the experimental data of Keller and Jones. Diffusion resistance is shown to be important in RPSA.
