Abstract:

The method of sequential pumping consists in the fact that hydrocarbon liquids of different quality are pumped through one pipeline in separate batches of certain volumes. With sequential pumping, maximum utilization of the pipeline capacity is achieved, and other modes of transport are exempt from parallel transportation of petroleum products. However, a mixture is formed at the point of contact of successively moving liquids. The initial data for calculating the oil product pipeline are data on the annual volume and properties of petroleum products intended for transport, the pumping range, permissible concentrations of petroleum products in each other, as well as the profile of the route. In the hydraulic calculation of oil product pipelines, the same rule is maintained as in the calculation of oil and gas pipelines: it is performed for the most unfavorable conditions.

Keywords: characteristics of the Ufa-Samara trunk highway, properties of pumped petroleum products, calculation of parameters of sequential pumping of petroleum products, control of sequential pumping, mixtures by changing density, dielectric constant, ultrasound propagation velocity, optical density, viscosity, indicators
