摘要
炼油催化剂在生产过程中,常产生含粉尘、氮氧化物等污染物的尾气。随着环保排放要求的提高,需选用合适的技术,对尾气进一步净化。通过对除尘、脱硝技术的比选,采用云式除尘与低温氧化脱硝技术组合,深度脱除生产过程尾气中的粉尘、氮氧化物,使其质量浓度分别降至20 mg/m^3和100 mg/m^3以下,满足《石油化学工业污染物排放标准》(GB 31571—2015)特别排放限值要求。该一体化系统操作简便,效果明显,运行稳定,适用于炼油催化剂生产过程外排尾气的净化。
In the production of refinery catalysts,the exhaust gas often contains pollutants such as dust and nitrogen oxides.It is necessary to use appropriate technology to clean the exhaust gas and meet the more strict emission requirements.Through the comparison of dust removal and denitration technologies,the combination of cloud-dedusting technology and low temperature oxidative denitration technology is used to deeply remove dust and nitrogen oxides from the tail gas in the production process and reduce their concentrations to 20 mg/m^3 and 100 mg/m^3,respectively,and meet the special emission limit requirements of the“Petrochemical Industry Pollutant Emission Standards”(GB 31571—2015).
