Abstract This paper presents the optimization results of the cyclic pumping of batches of high-pour-point and high-viscosity oil mixtures at the Uzen-Atyrau section of the Uzen-Atyrau-Samara main pipeline, taking into account on-route heating, boosting and pumping-out. The optimization criterion was the minimum total cost of power consumption by the pumping units and the preheaters.
