摘要
天津某化工企业ABS树脂装置HRG单元絮凝线干燥尾气中含有甲苯、乙苯、苯乙烯和VOCs等污染物,装置现有的尾气治理设施无法稳定达到最新行业特别排放限值要求,企业通过改造现有治理措施增加低温催化氧化装置,确保HRG絮凝线干燥尾气达到《合成树脂工业污染物排放标准》(GB 31572-2015)大气污染物特别排放限值及其它最新标准限值,同时最大限度降低有组织排口臭气浓度,为行业企业开展废气治理提标改造及异味减排提供借鉴。
The desiccated waste gas form HRG flocculation line process which is in a Tianjin chemical factory ABS resin unit,contains toluene,ethylbenzene,styrene,VOCs and other pollutants. The pollutants in the waste gas could not meet the requirements of the latest industry special emission limit before upgrading and reconstruction. So the factory improved the existing treatment measures and added the low temperature catalytic oxidation equipment to reach the special emission limit of Emission standard of pollutants for synthetic resin industry（ GB 31572-2015） and other latest standard limits. In addition,it can extremely reduce the stink,which comes from the waste gas. This successful project will provide references for waste gas upgrading and reconstruction and stink reduction.
