摘要：Development of cost-efficient denitration technologies has been a challenging task in industry. Here we proposed a new denitration method by using polypropylene hollow fiber membrane contactor. The NO gas from a simulative flue gas was absorbed into a saline aqueous solution through a holly fiber membrane, and then oxidized by the added H2O2 in the solution. We examined the effects of different operation parameters including the gas and liquid flow rates, the concentrations of H2O2 in the solution and SO2 in the mimic flue gas and the circulating time. The optimal operation parameters were identified. Finally, we make a conclusion that by using a PP hollow fiber membrane contactor and H2O2 aqueous solution with the addition of NaCl, is a new and effective method to remove NO.
