Abstract

The performance for gas separation by pressure swing adsorption is determined by four dimensionless parameters: pore diffusion (D_et_cla²) bed utilization (u_rt_rIL); purge-to-feed ratio (y); and feed composition (y₀). The unique dependence of the product purities on these parameters are shown for binary-mixture separation on activated carbon. The importance of pore diffusion in PSA separation for binary mixtures may be assessed by the threshold value of D_et_r!a= 43, above which pore diffusion is not important.
