【摘要】：空气中的SO2和NOX是大气中主要污染物之一,是衡量大气是否遭到污染的重要标志。石油炼制工业生产过程是SO2、NOX和颗粒物等大气污染物排放的主要来源。为了实现大气污染物控制的目标,国家制定出台了一系列法律法规、技术政策,加快了国产脱硫脱硝技术和设备的研究、开发、推广和应用,规定从2015年7月1日起,催化烟气中SO2、NOX、颗粒物排放浓度分别为100、200、50mg/Nm3,特别排放限值分别为50、100、30mg/Nm3。长庆石化公司随着催化原料性质恶化,催化烟气中SO2、NOX、颗粒物排放浓度分别为300mg/Nm3、600mg/Nm3、200mg/Nm3,远远超过国家规定。公司废气污染含量超标,已严重地影响了城市居民的生活,对炼厂职工的影响更大。如何进一步利用科学有效的方法脱除废气中的SO2、NOX及颗粒物,直接关系到企业的发展。通过对比国内外主要的烟气脱硫脱硝技术,结合长庆石化公司实际,选用了美国杜邦BELCO公司的EDV(?)湿法洗涤系统技术和抚顺石油化工研究院的SCR氧化还原技术。本文对这两种烟气净化工艺在长庆石化公司的应用和运行工况进行了分析,检验了QKJ-DN型脱硝剂的使用效果,特别是对SCR脱硝工艺在炼厂脱硝领域的应用积累了经验。
[Abstract]:So _ 2 and no _ X in the air are one of the main pollutants in the atmosphere, which is an important indicator to judge whether the atmosphere is polluted or not. The production process of petroleum refining industry is the main source of air pollutants such as so _ 2 O _ 2 O _ X and particulates. In order to achieve the goal of controlling atmospheric pollutants, the State has formulated a series of laws, regulations and technical policies, which have accelerated the research, development, promotion and application of domestic desulfurization and denitrification technologies and equipment, and stipulated that from July 1, 2015, The emission concentrations of so _ 2N _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O With the deterioration of catalytic feedstock properties, the emission concentration of particulates in catalytic flue gas from Changqing Petrochemical Company is 300mg / Nm3600mg / Nm3200mg / Nm3200mg / Nm3, which is far more than the national regulation. The pollution content of the company has seriously affected the life of the city residents and the workers of refineries. How to further use scientific and effective methods to remove so _ 2 no _ x and particulates from waste gas is directly related to the development of enterprises. By comparing the main flue gas desulphurization and denitrification technology at home and abroad and combining with the actual situation of Changqing Petrochemical Company, the EDV of DuPont BELCO Company was selected. Wet washing system technology and SCR redox technology of Fushun Petrochemical Research Institute. In this paper, the application and operation conditions of these two flue gas purification processes in Changqing Petrochemical Company are analyzed, and the application effect of QKJ-DN denitrification agent is tested, especially the experience accumulated in the application of SCR denitrification process in the field of denitrification in refineries.
