(223c) Equilibrium Theory Analysis of Equalization Tanks in a PSA Process
To begin to understand the role of tanks in a PSA process, an isothermal equilibrium theory analysis is carried. Analytic expressions are derived based on linear isotherm and an arbitrary binary feed stream to describe the performance of a simple PSA process at the periodic state that produces a pure heavy component at high recovery. To observe the effect of the number and size of the tanks, the performances are analyzed in varying number of equalization steps and volume of tanks in terms of the different concentrations and velocity profiles exhibited during various cycle steps. The latest result from this study will be presented.
