Improvement of Methods for Reducing Environmental Pollution During Transportation of Petroleum Products by Rail

It was established that the existing calculation methods for emission inventory based on averaged coefficients do not take into account regional climatic features and the specifics of technological processes, which leads to an underestimation of actual pollution volumes. Using the example of an industrial site in Khabarovsk Krai, a discrepancy between calculated and experimentally measured emission values is demonstrated. The spread of hazardous substances (benzene, toluene, etc.) beyond the boundaries of the industrial site was confirmed. A set of scientifically substantiated measures is proposed, including an improved emission measurement methodology and an effective technical solution in the form of a stationary tank sealing device, ensuring a reduction in fugitive atmospheric emissions, as well as an adsorption unit at operating unloading racks.
