All the gas exiting from the light reflux (LR) step is taken out as heavy product (HP). 3.4 PSA CYCLE PROCESS PERFORMANCE INDICATORS The PSA process was designed to produce enriched CO2 as the heavy product and take out N2 in the light product. The periodic state recovery and purity of CO2 in the heavy product and the recovery and purity of the N2 in the light product was used to judge the overall performance of the process, the average mole fraction of CO2 in the heavy product during the CnD step was taken as the purity of CO2 in the heavy product. The average mole fraction was calculated by averaging the mole fraction of the streams coming out of the CnD step. The recovery of this process was defined as the total amount of CO2 produced divided by the total amount of CO2 fed during the feed. The N2 recovery in the light product 17PDF Image | Development of a Pressure Swing Adsorption (PSA) Cycle for CO2 Capture
