摘　　要：以国内某炼厂为研究对象,从总流程角度对炼厂主要装置运行情况进行联合诊断,发现由于三环芳烃组分在重油加工系统恶性循环,导致生产中出现催化裂化柴油处理困难、柴油池个别批次十六烷值不达标等问题。采用Aspen公司的过程工业模型系统软件建立了全厂总流程模型,并进行原油保本价测算,提出了原油加工的优化结构;同时对优化前后的全厂流程进行模拟测算,提出了总流程优化方案。优化前后的实际运行数据对比及效益评估结果表明,产品结构得到明显改善,企业全年增效约1514.3万元,达到了炼厂运营优化和效益提升的目的,对同类型炼厂的全流程优化具有较好的借鉴意义。From overall process view,the operating status of a domestic refinery’s main units was diagnosed.Some problems in production,such as difficult treatment of fluid catalytic cracking diesel and insufficient cetane number of individual batches of diesel pool were found due to the vicious cycle of tricyclic aromatic hydrocarbons in heavy oil processing system.The process industry model system developed by Aspen company was used to build the overall process model of the whole plant.This model was used to calculate the breakeven price of crude oil,and propose the optimal structure of crude oil processing.The whole plant process under current and optimized conditions was simulated and calculated,and the overall process optimization scheme was put forward.The comparison of actual operation data before and after the optimization,and the result of benefit evaluation show that the product distribution has been obviously improved,and the annual benefit of the enterprise increases about 15.14 million Yuan,which has achieved both operation optimization and benefit improvement for the refinery.This study is also important in overall process optimization for refineries with the same type.
