摘　　要：以主分馏塔粗汽油终馏点为表征分离程度的独立变量,基于典型流程,结合流程模拟和数据回归技术,全面分析粗汽油终馏点变化对装置能耗、蒸汽产量以及产品产量的影响,并以此为基础总结了计算最优粗汽油终馏点的一般方法。将所建方法应用于某4.2 Mt/a延迟焦化装置,结果表明,该方法是可行的,按其求解的最优粗汽油终馏点操作,装置效益可提高767.9万元/a。The naphtha end point(x)from delayed coking distillation tower is taken as the independent variable representing the depth of separation.The relationships between xand energy consumption,steam production,product distribution are examined based on the process flow sheet,using the technology of process simulation and data regression.A general method of determining the optimal xis developed,considering the total economic benefit or total energy loss.The application of the method in a 4.2Mt/a delayed coker can improve the benefit of the unit about 7.679 million Yuan/a.
