Abstract:

The collaborative optimization of the supply chain of refining and chemical plant is crucial to the realization of intelligent refineries. The planning optimization system is the core system for the realization of collaborative optimization of the supply chain. This article introduces in detail the overall framework and main functions of the new generation of planning optimization software which independently developed by the PetroChina Planning and Engineering Institute. On the basis of this platform, combined with the boundary conditions of the refining and chemical integration enterprise process data, crude oil database and product sales, the design and construction of the refining and chemical integration model are carried out. Based on the principle of linear programming, the model is used to carry out various optimization analyses. Through marginal benefit analysis and multi-scenario comparative analysis, combined with different crude oil purchase methods such as the crude oil cost-preservation method, cost reduction method, and equivalent substitution method, the crude oil purchase calculation and application analysis were carried out, and the integration of refining and chemical plant was carried out. Processing crude oil put forward relevant suggestions to guide enterprises to purchase crude oil.
