CHAPTER 5 CONCLUSION A pressure swing adsorption (PSA) process has been described that is cable of separating CO2 from flue gas using 13X zeolite as adsorbent by a dual-reflux PSA cycle. The feed gas considered as a simulated dry flue gas consisting of 15.9% CO2 and balance N2 that was fed at 121 kPa and at 25 °C. A unique combination of cycle steps consisting of three beds was able to produce high purities (>90%) and high recoveries (>90%) of CO2 in the heavy product. The throughput achieved experimentally was 404 LSTP/hr/kg. A comprehensive experimental study was performed to determine the effect of different process conditions such as feed concentration, purge to reflux ratio, pressure ratio, bed temperature on the CO2 purity, CO2 recovery in the heavy product and the energy consumption (kJ/mol CO2 captured) by the PSA process. The study showed that purge to feed ratio has significant effect on the process performance. The CO2 recovery increased as the purge to feed ratio was increased. For all the experiment, the total effluent coming out of the LR step was recycled back as the feed to the HR step. By increasing, the purge to feed ratio more CO2 desorbs during the LR step and the bed regenerated better, but it also pushes the high concentration wave front further up the bed during the HR step. A smaller value of the purge to feed ratio causes less regeneration of the bed and the high concentration wave front does not travel through the bed more. Increasing value of the purge to feed ratio also increases the purity and recovery 36PDF Image | Development of a Pressure Swing Adsorption (PSA) Cycle for CO2 Capture
