Computer Software for Multicomponent Bulk Separation by Pressure Swing Adsorption: Equilibrium, Linear Driving Force and Bidispersed Pore Diffusion Models: Final Report, Part 2.

摘要

Three mathematical models (Equilibrium, Linear Driving force and Bidispersed Pore Diffusion Models) were developed to simulate and predict the performance of binary and multicomponent pressure swing adsorption processes. These models are capable of simulating all steps of the PSA cycle and predicting the effects of different process variables on the separation performance. Input data required by the models are equilibrium adsorption isotherms, and kinetic or diffusion data. Two FORTRAN programs were developed to simulate a PSA process for multicomponent bulk separation. In the subsequent sections, production of hydrogen from a coal gasification mixture (a mixture of H2 , CH4 , CO, CO2 and H2 S) using 5A zeolite is used as an example to explain the usage of the program. However, with slight modifications this software can be used for other PSA systems. 22 refs., 3 figs., 1 tab. (ERA citation 14:019444)
