摘　　要：“双碳”背景下,钢化联产是国家相关产业政策鼓励的发展方向。介绍了钢化联产基本概念、工艺路线以及常见的钢铁与化工耦合发展路径;简述了钢铁行业焦炉煤气、高炉煤气、转炉煤气用于燃料、发电、提氢、生产化工产品等综合利用现状;重点分析了钢化联产甲醇以及衍生品产业链、氢气(可联产天然气)产业链、乙二醇产业链、甲酸产业链、乙醇产业链的优点、不足及前景;测算了钢铁行业煤气用于加热燃料、发电以及钢化联产生产氢能、甲醇、乙二醇等化工产品的碳排放强度。综合行业发展趋势和我国能源消费结构调整政策,提出了企业实施“氢能+LNG+C(化学品Chemicals)”的钢化联产模式。The steel and chemical co-production is the development direction encouraged by relevant national industrial policies under the background of“carbon peaking and carbon neutrality”.The basic concepts,process route and common development paths of coupling of steel and chemical industry were introduced.The comprehensive utilization of coke oven gas,blast furnace gas and converter gas in iron and steel industry for fuel,power generation,hydrogen extraction and making chemical products was briefly described,with key analysis on the advantages,disadvantages and prospects of steel and chemical co-production for different industry chains,such as methanol and derivatives,hydrogen(co-production of natural gas),ethylene glycol,formic acid and ethanol.The carbon emission intensity of steel gas used for heating fuel,power generation and the steel and chemical co-production of hydrogen energy,methanol,ethylene glycol and other chemical products was calculated.Based on the industry development trend and China′s energy consumption structure adjustment policy,the steel and chemical co-production mode of“hydrogen energy+liquefied natural gas+chemicals”was proposed.
