考虑石脑油两种用途的原油混输调度模型

针对炼厂石脑油用于催化重整和乙烯生产两种用途的原油混输调度问题建立数学模型，把重整过程和乙烯生产对石脑油芳烃潜含量的不同要求用线性规划的方法实现，以原油混输调度中对不同类的原油根据需要分别输送和储存，为常减压装置准备好“重整石脑油方案”和“乙烯石脑油方案”的原料，真正符合“宜芳则芳”、“宜烯则烯”的调度原则。建模中应用了MILP(混合整数线性规划)技术和多周期技术，并给出一个应用在6种不同的国外原油及6个生产调度周期的应用实例，考虑了原油从装置罐到厂区罐的一次混输调度，尽量保证管道和厂区罐调度周期末原油质量合格。

Refinery scheduling of crude oil considering two different uses of naphtha

This paper addresses the scheduling of crude oil considering two different uses of naphtha to build mathematical model.Asdifferent aromatic potential content of naphtha is required by reforming process and ethylene process,the individual transportation andstorage of crude oil is determined from storage tanks to charging tanks.The purpose is just to prepare reforming naphtha program andethylene naphtha program for crude distillation unit effectively,which is called naphtha-scheduling rule.We use MILP( mixed-integerlinear program)and multiperiod techniques to build this model.The scheduling model of mixed transportation of crude oil in this paperwas applied to 6 different types of international crude oil and 6 time intervals,which involve the first transfer from storage tanks to char-ging tanks in order to largely ensure the quality of mixed oil in pipeline from storage tanks to charging tanks and the average quality oftotal amount of oil in storage tanks at the end of the last time interval.
