Abstract: The article provides theoretical provisions to calculate the most efficient way for immediate distribution of petroleum product mixtures generated during their serial transfer by means of direct contacting. The consequence of a serial transfer of petroleum products be means of direct contacting is the generation of mixture as a result of convection and turbulence mixing of transferred fluids. In order to eliminate losses due to occurrence of non-commodity mixtures, they are distributed to petroleum products they are formed of. Hence, the so called mixture distribution is made. The distribution shall be made in such a way, that the quality level of commodity petroleum products corresponds to the established regulatory values after the mixture is completely distributed into such petroleum products. A way of immediate distribution was proposed to reduce temporal and production losses for mixture distribution, by means of directing the mixture directly to vessels with commodity oil products, without their pre-transfer to mixture vessels. The implementation of the method stipulates serial calculation of base ratio of petroleum products in the mixture and possible amounts of its distribution to the vessels with petroleum products. The calculations are made with taking in account limited accepted concentration for the content of one mineral in another one. The article considers the procedure of calculating two possible options of an immediate distribution: with a uniform mixture supply to several vessels and with a differentiated mixture supply to connected vessels. The second method is characteristic of vessels with a different level of petroleum product content.

Keywords: petroleum products, series pumping, gasoline, diesel fuel, limited accepted concentrations, immediate mixture distribution
