ժҪ Byproduct gas is an important secondary energy in iron and steel industry,and its optimization is vital to cost reduction. With the development of iron and steel industry to be more eco-friendly,it is necessary to construct an integrated optimized system,taking economics,energy consumption and environment into consideration. Therefore,the environmental cost caused by pollutants discharge should be factored in total cost when optimizing byproduct gas distribution. A green mixed integer linear programming (MILP) model for the optimization of byproduct gases was established to reduce total cost,including both operation cost and en-vironmental cost. The operation cost included penalty for gas deviation,costs of fuel and water consumption,holder booster trip penalty,and so forth; while the environmental cost consists of penalties for both direct and indirect pollutants discharge. Case study showed that,compared with previous model,the proposed one brought an optimum solution and 2.2% of the total cost could be reduced.
