摘要：Steam power system(SPS) is not only a major energy-consuming enterprises but also a major source of pollutants. The steam power system should be operated under the optimal scheme to meet the varying demand and power from process, to reduce cost and save energy for petrochemical industry. Considering the impact of steam power system to human environment, a mixed-integer nonlinear programming(MINLP) model including the maintenance of equipment, changeover costs and environmental costs was established. By using particle swarm optimization(PSO) calculation method to solve this model, reasonable optimal operation plan can be obtained. Although considering environmental costs as part of the total cost increases the total business operating costs, to resolve the issue of environmental protection and coordinated and sustainable economic and social development has very important significance.
