Optimization of Oil Blending to Increase the Efficiency of Joint Pumping in the System of Trunk Oil Pipelines

Abstract

The article proposes a methodology for calculating the factors of rational mixing of oils with various rheological properties that are jointly transported through an extensive system of trunk pipelines to save energy demands for pumping. The calculation is aggravated by the absence of additivity of viscosity of specially formed multicomponent blends of oils that compels the calculation in a simplex place that characterize the possible compositions of oil blends. It is proposed to use the standard polydimensional optimization strategy as the main calculation module. The objective is presented in the form of summarized energy demand for pumping depending on the concentration of oil blend at the nodal points of their blending. There is proposed a method for calculating the objective for any extensive network of oil trunk pipelines using algorithms of constructing a blend tree and determining its properties using traversal tree algorithm.
