英文摘要Pressure and Temperature Swing Adsorption (PTSA) is an appealing purification technology for removing low CO2 concentration from confined space potentially. In this work, a systematic method integrating dynamic process simulation, sensitivity analysis, process optimization, and energy consumption assessment was established to investigate a PTSA process of low CO2 concentration separation in the confined space using two adsorbents (Zeolite 13X and NaUSY). The dual site Langmuir adsorption isothermal models of N-2 and CO2 were established, and calculated results showed good agreement with the experimental data. After parametric sensitivity analysis, key operational parameters (i.e. adsorption pressure, desorption pressure, regeneration temperature and P/F ratio) were optimized to achieve minimum process energy consumption. Those results indicated that Zeolite 13X was a good candidate for separating low concentration CO2 from confined space with lower energy consumption (55.03 kJ.Nm(-3) N-2). The simulation result can provide a novel strategy for removing low CO2 concentration from confined space.
