摘要
介绍了城市煤气的组分和性质;分析了大同煤矿集团煤气厂利用富余的城市煤气联产5万t/a甲醇新工艺的流程,由直立炉和水煤气两段炉生产的煤气经过压缩、变换、脱碳、精脱硫、合成、精馏作业后,可制得精甲醇;在设计、施工、投料过程中,该厂精心组织,严格把关,保证了一次开机成功。
The composition of town gas and properties given;analyzed was the new process for co-production of 50kt/a methane from excess town gas at the coal gas plant of Datong Coal Mines Group;by vertical retort and two-stage furnace for water-gas,coal gas produced,from which qualified methane can be produced by subsequent compression,conversion,de-carbonization,syntheses and distillation.In the course of design,construction and material feeding,collaborate organization and strict regulation were taken that the production was successful at first operation of the process.
