摘　　要：流程工业模型系统(PIMS)可以模拟流程工业企业的生产经营过程,通过对比分析,发现加工流程中的瓶颈,并找出最佳解决方案,为企业的生产经营提供决策依据。青岛石化公司是典型的单系列燃料型炼厂,公司的PIMS模型目前在原料油采购、产品结构调整、调合配方确定、生产经营瓶颈分析及炼厂规划转型等生产优化业务中发挥着重要作用。开展原料油优化,统筹原油性价比和配置计划等多方面因素,选定杰诺原油作为主力油种,制定了掺炼高硫重油的加工方案,量化了外采油浆的价格优势;开展产品结构优化,在当前市场需求下,明确了回炼至催化装置是剩余常压柴油的最佳流向,吨油效益476元/t;开展调合配方优化,确定降低低硫船燃生产成本的有效途径是增加渣油组分占比,月度增效634万元;开展规划转型优化,制定了企业低硫船燃转型发展之路,2021年企业加工负荷、吨油效益及各项技经指标大幅提升。在炼厂生产优化方面运用好PIMS模型,重点是要做好准确、及时地修正调整模型,制定适当宽松的约束条件,闭环管理以及紧贴市场价格变化和生产实际情况。Process Industry Modeling System(PIMS) can simulate the production process of enterprises in the process industry,identify the bottlenecks in process flow through comparative analysis and find the best solutions,so as to provide basis of decision for the production and operation of enterprises.SINOPEC Qingdao Petrochemical Co.,Ltd.is a typical single-train fuel-based refinery.Its PIMS model currently plays an important role in production optimization operations such as feed oil procurement,product structure adjustment,blending recipe determination,production and operation bottleneck analysis and refinery planning transformation.Feed oil optimization was carried out.Considering various factors such as cost performance and allocation plan of crude oil,Djeno crude oil was selected as the main oil,the processing scheme of blending high sulfur heavy oil was developed,and the price advantage of outsourcing oil slurry was quantified.Product structure optimization was carried out.To meet the current market demand,it was clarified that recycling to FCC unit is the optimal flow direction of surplus atmospheric diesel oil,with a profit of 476 yuan per ton.Blending recipe optimization was carried out.It was determined that the effective way to reduce the production cost of low sulfur marine fuel is to increase the proportion of residue components,with a monthly benefit growth of 6.34 million yuan.Planning transformation optimization was carried out.The road for transformation and devel-opment of low sulfur marine fuel was developed for enterprises.In 2021,the processing load,profit per ton of oil and various technical-economical indexes of the enterprises were greatly improved.To make good use of PIMS model in refinery production optimization,the model should be accurately and timely corrected and adjusted,the moderately loose constraints should be developed,the closed-loop management should be carried out,and the market price changes and the actual production should be closely followed.
