ASSESSMENT OF THE POLLUTING EFFECTS OF LOCAL PETROLEUM PRODUCT SPILLS ON THE ENVIRONMENT WHEN UNLOADING OUT OF RAIL TRANSPORT

The paper gives an assessment of the polluting effects of petroleum product spills on the environment resulting from full and partial depressurization during unloading of railway tanks, performed using geoinformation systems. The study objective is to model emergency situations associated with an unauthorized spill of petroleum products in order to assess in detail the degree of polluting effect on the environment. The relevance and scientific novelty of the work is in calculating harmful and dangerous indicators, which are used for the first time to assess the negative impact within the petroleum cargo unloading area. The practical importance of this paper is in predicting the development of an emergency situation with reference to timeframe, and its results can be further taken into account when planning measures to localize and eliminate emergencies.
