催化裂化再生烟气脱硫脱硝装置运行效果分析

Analysis on operation effect of catalytic cracking off-gas desulphization and denitrification unit

介绍了美国BELCO公司的EDV~? 6000湿法烟气脱硫技术及配套LoTO_x^(TM)氧化脱硝技术工艺流程和特点。齐鲁石化采用该技术对800 kt/a催化裂化装置再生烟气进行净化处理,运行结果表明:净化烟气中ρ(SO_2)<30 mg/m^3、ρ(NOx)<50 mg/m^3、颗粒物(ρ)<20 mg/m^3,均满足《石油炼制工业污染物排放标准》(GB 31570—2015)和《山东省区域性大气污染物综合排放标准》(DB 37/2376—2013)的排放要求。

Process flow and characteristics of USBELCO company EDV 6000 wet off-gas desulphurization technology and LoTOx ozone oxidation denitration technology are introduced. This technology was used for the purification regenerated off-gas of 800 kta catalytic cracking unit in Qilu Branch Co. Operation results show： SO2 concentration is less than 50 mg/m3 and particle mass concentration is less than 20 mg/m3 in purified off-gas,meet the emission requirements ofdischarge standard of pollutants for petroleum refining industry GB 31570 -2 0 1 5 ad Shannong province regional integrated emissionstandard of air pollutants DB 37/2376 -2013.
