【摘要】：催化裂化再生煙氣中含有大量的SOx和NOx,已成為我國煉廠主要的空氣污染源。根據(jù)"十二五"綱要對煙氣中SOx和NOx減排的要求,催化裂化煙氣執(zhí)行脫硫脫氮達(dá)標(biāo)勢在必行。本文先后對國內(nèi)外煙氣脫硫脫硝技術(shù)進(jìn)行分析討論,結(jié)合催化裂化裝置特點(diǎn),對催化煙氣脫SOx、NOx工藝進(jìn)行選擇,綜合考慮技術(shù)、節(jié)能、經(jīng)濟(jì)、安全、操作可靠性等因素,確保煙氣中NOx和SOx排放達(dá)到國家最新的排放標(biāo)準(zhǔn)。本文對吉林石化MIP-CGP催化裂化裝置EDV濕法洗滌煙氣脫硫工藝進(jìn)行可行性分析及應(yīng)用效果評價,并從吉林石化MIP-CGP催化裂化裝置的實(shí)際出發(fā),通過數(shù)據(jù)對比分析臭氧氧化脫硝技術(shù)及選擇性催化還原法脫硝技術(shù)在應(yīng)用上的差別,并從經(jīng)濟(jì)效益、使用效果等進(jìn)行全方面的評價。
[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.
