【摘要】：催化裂化再生烟气中含有大量的SOx和NOx,已成为我国炼厂主要的空气污染源。根据"十二五"纲要对烟气中SOx和NOx减排的要求,催化裂化烟气执行脱硫脱氮达标势在必行。本文先后对国内外烟气脱硫脱硝技术进行分析讨论,结合催化裂化装置特点,对催化烟气脱SOx、NOx工艺进行选择,综合考虑技术、节能、经济、安全、操作可靠性等因素,确保烟气中NOx和SOx排放达到国家最新的排放标准。本文对吉林石化MIP-CGP催化裂化装置EDV湿法洗涤烟气脱硫工艺进行可行性分析及应用效果评价,并从吉林石化MIP-CGP催化裂化装置的实际出发,通过数据对比分析臭氧氧化脱硝技术及选择性催化还原法脱硝技术在应用上的差别,并从经济效益、使用效果等进行全方面的评价。
[Abstract]:FCC regenerated flue gas contains a large amount of SOx and no _ x, which has become the main air pollution source of refinery in China.According to the requirement of emission reduction of SOx and NOx in flue gas according to the "12th Five-Year Plan", it is imperative for FCC flue gas to meet the standard of desulfurization and denitrification.The technology of flue gas desulfurization and denitrification at home and abroad has been analyzed and discussed in this paper. Combined with the characteristics of catalytic cracking unit, the process of removal of so _ x no _ x from catalytic flue gas has been selected. The technical factors, such as energy saving, economy, safety, operation reliability and so on, have been considered synthetically.Ensure that NOx and SOx emissions in flue gas meet the latest national emission standards.In this paper, the feasibility analysis and application effect evaluation of EDV wet washing flue gas desulfurization process in Jilin Petrochemical MIP-CGP catalytic cracking unit are carried out, and the actual conditions of MIP-CGP catalytic cracking unit in Jilin Petrochemical Company are discussed.The difference of ozone oxidation denitrification technology and selective catalytic reduction denitrification technology in application was analyzed by comparing the data, and the economic benefit and application effect were evaluated in all aspects.
