富氧燃烧烟气压缩净化的研究进展
Research and development on the purification of oxy-fuel combustion flue gas in the process of compression
摘要
Abstract
Oxy-fuel combustion technology can reduce the NOxand SOxemissions per unit fuel. However,the presence of pollutants such as acid and mercury has a great impact on the subsequent utilization and storage of CO2. Based on the purification technology of the oxy-fuel combustion flue gas,the removal of NOxand SO2and their combined removal in CO2compression process are briefly described to explore the interaction between NOxand SO2in the combined removal process and the path of N-S reaction. The research progress of combined mercury removal in compression process is analyzed to discuss the specific mechanism and the effects of NOx,SO2and H2O on the removal of mercury. Finally,pilot scale application of compression purification technology is introduced. The analysis shows that most of the existing researches focus on the individual analysis of the effects of various operating conditions on the removal of NOx,SO2and HgO. Therefore,it is difficult to reveal the internal relationship and interaction mechanism among the removal of pollutants. In order to realize the effective purification of the rich CO2flue gas,the combined removal of pollutants such as NOx,SOxand HgO should be realized. Thus,the equipment investment and operation cost of oxy-fuel combustion technology can be greatly reduced,and the large-scale commercial application of the technology can be promoted effectively.关键词
