石油加氢裂化过程的经济最优化 (Ⅲ)按经验产品分布关系处理的多产品系统

THE ECONOMIC OPTIMAZATION OF PETROLEUM HYDROCRACKING(HC)PROCESS(Ⅲ)MULTI-PRODUCT SYSTEM WITH EMPIRICAL PRODUCT DISTRIBUTION MODEL

本文按经验产品分布关系对液化石油气、石脑油、航空煤油及柴油的收率作归一化处理,得到全循环和一次通过加氢裂化过程的利润模型:并以利润为目标对操作过程进行了优化,得出了过程最佳单程转化率以及相应的最佳产品分布。文中海讨论了后续工程配套生产对加弗裂化运行经济性能的影响。

There exists an optimal single-pass reaction conversion to each operation scheme of HC process which was determined by prduct prices and cost factors to reach the maximum operation profit,cor- respondingly the optimal opertion condtions were defined.A model plant was assumed to illstrate the optimizing results.
