Application of a Mathematic Programming Model for Integrated Planning and Scheduling of Petroleum Supply Networks

Abstract

The scope of this study is concerned with the petroleum supply network operated by a typical oil company, in which the crude oil is consumed to produce ethylene, propylene, liquefied petroleum gas, butadiene, benzene, toluene, xylene, gasoline, kerosene, diesel, and other byproducts. These petrochemical products are usually manufactured with a cluster of strategically located conversion refineries.1 A complete petroleum supply chain consists of at least 13 different types of production units, that is, the atmospheric distillation units, the vacuum distillation units, the cokers, the fluid catalystic cracking units, the naphtha crackers, the butadiene extraction units, the hydrotreaters, the aromatics extraction units, the reforming units, the xylene fractionation units, the parex units, the xylene isomar units, and the tatory units. Traditionally, the production plan of an industrial supply chain is created first and a compatible schedule is then identified accordingly. Because the detailed scheduling con...
