摘　　要：煤经汽化制甲醇过程中部分装置尾气中CO和H_(2)组分含量较高,生产企业可作为燃料气,也可从中提取H_(2)作为下游装置原料。通过对煤化工企业的甲醇装置尾气组成分析,列出了3种不同尾气利用方案和流程图,计算了不同利用方案的物料平衡及成本构成。通过对不同方案产品产量变化及经济性的详细对比,对不同情况下装置尾气中的热能、CO和H_(2)组分的综合利用途径进行分析。最终提出通过调整工业装置的气相分配方案,可在不新增装置的情况下回收利用工业尾气做燃料气,同时增产H_(2),综合经济收益较好。The industrial exhaust gas from some units in coal gasification to methanol process has high CO and H_(2) contents.Coal chemical enterprises can use such exhaust gas as fuel gas or extract H_(2) as raw material for downstream units.By analyzing the composition of exhaust gas from methanol plants in coal chemical enterprises,this paper proposes three different exhaust gas utilization schemes and flow charts,and calculates the material balance and cost structure of these schemes.With a detailed comparison of the product output changes and economic efficiency of different schemes,the comprehensive utilization paths of heat energy,CO and H_(2) components in the exhaust gas under different conditions are analyzed.The scheme of adjusting the gas phase distribution can recycle the industrial exhaust gas as fuel gas without adding new units and increase the production of H_(2),achieving good economic benefits.
