ОЦЕНКА ВЕРОЯТНОСТИ РЕАЛИЗАЦИИ НА ГОЛОВНОЙ НЕФТЕПЕРЕКАЧИВАЮЩЕЙ СТАНЦИИ АВАРИЙНЫХ СИТУАЦИЙ, ПРОТЕКАЮЩИХ ПО РАЗЛИЧНЫМ СЦЕНАРИЯМ

Abstract

The work of enterprises in the agro-industrial complex is closely connected with the use of petroleum products, the use of which is ensured through oil pumping stations. The assessment of the probability of emergency situations at such enterprises was carried out using the example of the main oil pumping station GNPS-1 “Taishet” of TransnefteVostok LLC. It is shown that the enterprise belongs to objects of increased fire danger, the most dangerous technological areas of which are the tank farm, the main oil pumping station and the booster pumping station. A fire and explosive substance - oil is circulated in a technological scheme. Possible ways of developing emergency situations associated with the failure of equipment in individual technological sections of an oil pumping station were investigated in the work. The most dangerous accidents occur in three areas: in the tank farm, at the main and booster pumping stations. The probabilities for the development of emergency situations have been determined. It was revealed that the most dangerous scenarios are possible at any of the reservoirs of the tank farm and at the main oil pumping and booster pumping station. In both scenarios, an instant spill fire, a spill fire with delayed ignition, and an explosion of a vapor-air cloud are possible. The cause may be a failure of emergency ventilation and a vapor-air cloud gas analyzer. The studied options for the development of an accident on technological equipment will make it possible to establish the scale of the consequences of the spread of dangerous factors of fire and explosion, as well as to determine a set of measures to prevent emergency situations, timely response and minimize their consequences.
