A hybrid system combining pressure swing adsorption (PSA) and gas membrane was investigated to recover low concentration CO2. At the first stage, a membrane unit concentrates the feed stream, and at the following stage, a PSA produces the purified gas rich in carbon dioxide. The membrane unit increases the concentration of the carbon dioxide from 15 to 40% by tube side feeding. The flow rate of permeate records more than 100 N1/min, which is sufficient to fulfill the PSA capacity. The PSA cycle consists of pressurization, adsorption, blowdown, rinse, and desorption steps. The cycle configuration is determined to accomplish the purity of 99%. A higher heating rinse than normal rinse by 10°C resulted in 10% augments in recovery and productivity.
