摘要
以某炼化企业催化裂化装置为例,针对不同的政策时期对催化裂化烟气污染物进行分段治理。首先利用现有煤炉脱硫设施进行催化烟气和煤炉烟气联合二氧化硫治理,脱硫率90%以上。其次采用SCR催化还原技术进行烟气脱硝治理,控制氮氧化物浓度小于50 mg/Nm^3。随着环保治理的深入推进,有色烟羽等治理是现阶段需要完成的任务。
Taking the FCC unit of a refinery as an example,the FCC flue gas pollutants were treated in stages according to different policy periods.Firstly,the existing coal furnace desulfurization facilities are used to treat FCC flue gas and coal furnace flue gas,the desulfurization rate is more than 90%.Secondly,SCR catalytic reduction technology is used to treat flue gas and control the concentration of nitrogen oxides less than 50 mg/Nm^3.With the further development of environmental protection,the treatment of colored smoke plume is a task that needs to be completed at this stage.
