Abstract :
The model of pressure swing adsorption separation process for CO2 with zeolite molecular sieve is established in this paper. The pressure swing adsorption system of CO2 is simulated with mass, gas and energy balance equations. The CO2 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 CO2 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 CO2/N2 pressure swing adsorption separation process with zeolite molecular sieve.
