摘　　要：高炉煤气为钢铁生产过程中产生副产的一种煤气,其产量巨大,可为钢铁生产其他工段提供燃料或作为发电使用,用户众多,但其成分里含有硫,燃烧后烟气里二氧化硫超过排放标准,如果在尾端烟气中脱硫,会造成投资大、运行成本高、占地面积大等,因此直接对高炉煤气进行脱硫,经济效益较好。目前高炉煤气脱硫工艺主要有吸附法及催化水解法,两种工艺均有投产装置,但各自也存在一定的缺点。Blast furnace gas is a kind of by-product gas produced in the process of steel production.Its output is huge.It can be used as fuel for other sections of steel production or used for power generation.There are many users,but its composition contains sulfur.Exceeding the emission standard,if desulfurization in the tail flue gas,it will cause large investment,high operating cost,large area,etc.Therefore,direct desulfurization of blast furnace gas will have better economic benefits.At present,blast furnace gas desulfurization processes mainly include adsorption method and catalytic hydrolysis method.Both processes have put into production equipment,but each has certain shortcomings.
