固定床碎煤加压气化是煤制天然气的核心工艺,其挥发性有机物(VOCs)排放源头分散、组分复杂且常含硫化氢(H
2
S),治理难度较大。为解决该工艺的VOCs治理难题,对各种治理技术进行了对比。首先介绍了催化燃烧、蓄热式热氧化等治理技术的适用性,然后结合某大型煤制天然气项目的实测数据,深入剖析了从气化到污水处理全流程各装置的含VOCs废气排放特征,并提出了分类治理策略。最后,对固定床碎煤加压气化VOCs综合治理的未来发展进行了展望。
The fixed-bed crushed coal pressurized gasification process is the core technology of coal-to-natural-gas production. However
the emission sources of volatile organic compounds (VOCs) in the process are scattered
with complex components and often containing hydrogen sulfide
making the treatment extremely difficult. To solve the difficult problem of VOCs treatment in the process
various treatment technologies were compared. Firstly
the applicability of treatment technologies such as catalytic combustion and regenerative thermal oxidation was introduced. Then combined with the measured data of a large-scale coal-to-natural gas project
the emission characteristics of VOCs-containing waste gas from each device throughout the entire process from gasification to sewage treatment were deeply analyzed
and classified treatment strategy were proposed. Finally
the future development of the VOCs comprehensive treatment in fixed-bed crushed coal pressurized gasification was prospected.
