【 摘 要 】

Oxy-fuel combustion is considered as one of the most promising technologies for capturing CO2from coal-fired power plants. It will greatly reduce the cost of gas purification if we remove NOxin the process of compression, which is the characteristic of oxy-combustion. In this paper, simulation of denitration process of oxy-fuel combustion flue gas was realized by the Aspen Plus software, systematically analyzed the effect of temperature, pressure, initial concentration of O2and NO in the denitration process. Results show that the increasing of pressure, initial concentration of O2, initial concentration of NO and the decrease of temperature are all beneficial to the denitration process.
