摘要：
Gas-liquid contactors equipped with polytetrafluoroethylene (PTFE) or polypropylene (PP) hydrophobic membranes were applied for removal of sulfur dioxide from refinery gas. Pure water, NaOH solution and MDEA were adopted as the absorbents. The performance of the two kinds of membranes for separation of SO(2) was evaluated in terms of the concentration of absorbent solution, the concentration of SO(2), and the feed flow rate. The efficiency for removal of SO(2) increased with an increasing absorbent concentration. Upon increasing the concentration of SO(2) and the Iced flow rate, the desulfurization efficiency was decreased.
