Primary oil processing optimization

Abstract

The paper discusses oil distillation into target products with regard to the unclear separation effect. As the input data, the table of physical and chemical properties of narrow fractions is used. The problem is solved using the dynamic programming method. The methodology is realized in the authors' software product. Primary oil processing takes place mostly in CDU (crude distillation units). There oil is separated in a number of target products: gasoline, kerosene, diesel, vacuum tower bottoms. Oil is characterized by a true boiling temperature (TBT) curve reflecting the relation between the temperature and distillation cuts' fractions. In practice, TBT is a compilation of narrow fractions with end points [ , ]
