Abstract: The technology of consecutive pumping of oil products is considered, in order to reduce the mixture of petroleum products in the contact area of the transported lots, a separation plug is formed by introducing of drag reducing additive (DRA) into the liquid. Such an additive reduces not only the coefficient of hydraulic resistance, but also the turbulent diffusion in the flow of the transported liquid. As a consequence, the longitudinal mixing of the contacting liquids decreases and, consequently, the volume of the resulting mixture. However, the separation plug, having a relatively small size, gradually loses the DRA due to the mixing with the oil products between which it is located. The purpose of this paper is to determine the initial concentration of the DRA contained in the plug, which would ensure its effectiveness throughout the entire pumping process.

Keywords: oil product pipeline, batching, interface of oil products, oil product mixture, DRA concentration, separation plug, drag reducing additive, reduction of mixture volume, calculation of the separation plug volume.
