利用PIMS模型测算不同原油的保本价,高、低硫及轻、重质原油的价差平衡线,作为确定原油采购方案的依据;利用PIMS模型测算轻、重质原油在不同负荷下的优化搭配选择,优化原油采购方案;利用PIMS模型的方案对比法,优化现货原油的采购方案.通过实际应用案例,简要介绍PIMS模型在原油采购优化工作中的应用情况.结果表明,PIMS模型在中国石化青岛炼油化工有限责任公司原油采购优化工作中发挥了较好的作用.%The application of Processes Industry Modeling System (PIMS) model in procurement of crude oil is introduced in this paper. The model is used to calculate prices of various crude oil at their breakeven points and to simulate the spreads between equilibrium price lines when comparing light crude from heavy crude or between low sulfur crude and high sulfur crude,which is very helpful to the setting up of purchasing plan. This model can be used to find the optimum crude oil allocation in terms of light and heavy during various distillation processing capacities. The optimized cases of spot crude oil procurement are also investigated and compared through PIMS model. Various real case simulations are presented briefly. The results show that PIMS model has played a sound role in optimizing procurement process of crude oil in SINOPEC Qingdao Refining & Chemical Company.
