摘要
在试验基础上应用Aspen Plus建立了加压单独脱硝模拟流程,系统分析压力、温度、初始氧浓度、初始NO浓度以及烟气中N_2的存在对加压脱硝过程的影响。结果表明,NO脱除率随着压力、初始氧浓度、初始NO浓度的升高和温度的降低逐渐升高,且烟气中N_2的存在不利于加压脱硝过程;升压过程仅能脱除部分NO,若要脱除到满足工业要求需要保证足够的停留时间。
Based on experiments, the simulation process of pressurized denitrification was established by Aspen Plus, then the effects of pressure, temperature, initial oxygen concentration, initial NO concentration and the presence of N2 in the flue gas on the pressurized denitrification were systematically analyzed. The results showed that the removal rate of NO increased with the increasing of pressure, initial oxygen concentration, initial NO concentration and the decreasing of temperature. The presence of N2 in flue gas was unfavorable to the pressurized denitrification process. The increase of pressure could only re- move part of NO, and if the NO was removed to meet the industrial requirements, sufficient residence time was required.
