چکیده
The optimal scheduling of crude-oil operation in refineries has been studied by various groups during the past decade, leading to different mixed integer linear programming or mixed nonlinear programming formulations. This paper proposes a new MINLP formulation with an oil residency time constraint and common pipeline transportation that is based on single-operation sequencing (SOS). An effective choice strategy for priority-slot number is presented. This model is also developed upon the representation of a crude-oil scheduling by a single sequence of transportation operations. A method is proposed to solve this model which can get optimal solution with the smallest priority-slot number if it exists.

متن کاملPriority-Slot-Based Continuous-Time MINLP Formulation for Crude-Oil Scheduling Problem with Two-Pipeline Transportation
Some oil refineries arrange low-fusion-point crude oil storage tanks and ones containing high-fusionpoint crude oil at two diverse locations. Refinery needs different pipeline to transport different fusion point oil, so, to transport diverse fusion point oil it needs two pipelines. Because of the constraints resulted from transporting high-fusion-point oil, to schedule such a system is very har...

The problem addressed in this work is to develop a comprehensive mathematical programming model for the efficient scheduling of oil-refinery operations. Our approach is first to decompose the overall problem spatially into three domains: the crude-oil unloading and blending, the production-unit operations and the product blending and delivery. In particular, the first problem involves the crude...
