Influence of multiproduct pipeline telescopicity design on the process of mixing during sequential pumping

In the present paper, the research of the processes of mixture formation is carried out using the method of transportation of light petroleum products — sequential pumping by direct contact. Modeling of the processes of mixture formation is carried out taking into account the influence of parametric factors. This paper is based on a previously published work on non-isothermal pumping of petroleum products in a pipeline. It is also worth noting that in this work, a mathematical model has been finalized to consider the increase in accuracy, namely, accounting in a telescopic pipeline. To perform numerical simulation, a software package was developed that is capable of not only modeling and calculating the parameters of the petroleum product pipeline operation in real time, followed by graphical visualization, but also comparing the obtained data with the real data processed by operators at industrial facilities.
