چکیده:

A dynamic model for a N2-PSA system is developed based on linearized mass transfer rate expressions and biocomponent langmuir isotherm. Constant pressure is assumed during adsorption and desorption but nonlinear relationship for pressure is considered during the pressurization and blow down steps. The mass transfer equations are considered and developed for all steps. After, the proposed model is validated using experimental data; the simulations studies are performed on investigate the effect of changing various process variables, such as duration of PSA steps, bed length and feed inlet velocity.
