Solving the Problem of Reducing Atmospheric Pollution From Oil Product Vapors in Conditions of Their Continuous Transhipment and Growth of Freight Traffic

The paper presents the results of analyzing the actual problem of pollutant emissions into the atmosphere due to the evaporation of petroleum products during their discharge from railway tanks into reservoir at transshipment points and oil depots. A method is proposed to reduce significantly the amount of emissions of these substances into the atmosphere without using expensive vapor absorption and recovery plants. The study objective is to reduce the polluting impact on the environment caused by operating procedures at transshipment points and oil depots. The relevance and scientific novelty is in proposals to change the typical operating scheme of discharge by looping it, taking into account the physico-chemical features of the evaporation of petroleum products from reservoirs. The practical significance of this work is in the development of an economically feasible method for removing the vapor-air mixture in conditions of constantly recurring operating procedures for unloading petroleum products from railway transport and the development of a solution to achieve the goal of reducing the negative impact on the environment.
