摘　　要：采用Aspen Icarus Process Evaluator(Aspen IPE)软件对双气头多联产流程中关键工艺段——洁净气化煤气/焦炉煤气合成醇醚燃料单元进行了经济评价,以估算多联产系统中化工产品生产部分的经济性。经济评估计算以焦炭产能5000t/a的焦化厂为例,原料气按照气化煤气/焦炉煤气体积比1∶1进行输入,化学品合成工艺按一步法合成二甲醚(386t/a),副产甲醇(242t/a)。应用AspenIPE软件计算该流程的投资费用、操作费用和利润率,并在此基础上分析了原料和产品价格变化对该项目经济性的影响。To evaluate the economic feasibility of chemical products synthesis unit in dual-gas polygeneration system,Aspen Icarus Process Evaluator (Aspen IPE) is used to evaluate the alcohol ether fuels synthesis unit,a key unit of dual-gas polygeneration system which starts from clean gasified gas and coking-oven gas.Economic assessment calculation is done taking a coking plant producing 5 000 t/a coke as basis.Gasified gas and coking-oven gas are fed at the volume ratio of 1∶1 to produce DME (386 t/a),and 242 t/a methanol as byproduct using one-step synthesis process.On the basis of the calculation of the investment cost,operating cost and profitability by Aspen IPE,the impact of price change of raw material gas and products on the commercial feasibility of this project are analyzed.
