多种废气处理技术在40亿m3/a煤制天然气项目中的综合应用

摘要

对某新建40亿m3/a煤制天然气项目的各主要废气污染源按照组成、气量、排放规律等进行了系统分析，按照各自特点选用包括焚烧、蓄热氧化、光催化氧化、冷凝及吸附在内的多项废气处理技术，大幅消减大气污染物的排放量。%Main exhaust gas pollution sources of a 4 ×109 m3/a coal to gas (CTG) project were analyzed systematically on the aspects of composition, amount and emission rules of the exhaust gases. Several exhaust gas treatment technologies, incineration, regenerative thermal oxidation, photocatalytic oxidation, condensation and adsorption, were chosen and applied to treat the exhaust gases, which reduced greatly the emission of the air polutants.
