Research on the Separation Process Model of Pressure Swing Adsorption for CO_2/N_2 with Zeolite Molecular Sieve

摘要

The model of pressure swing adsorption separation process for CO_2 with zeolite molecular sieve is established in this paper. The pressure swing adsorption system of CO_2 is simulated with mass, gas and energy balance equations. The CO_2 adsorption isotherm is fitted by Dual-site Langmuir equation. The recovery rate, productive rate and energy of the separation process is designed. Finally, the model is validated by CO_2 of power plant flue gas with zeolite A and zeolite A+X. The result data of experiment and model simulation shows that our model is reliable in simulating the CO_2/N_2 pressure swing adsorption separation process with zeolite molecular sieve.
