THE TECHNOLOGICAL OIL REFINING UNITS RANGING ON THE BASE OF INDUSTRIAL SAFETYGENERALIZED CRITERIA

Abstract

The article is devoted to an assessment of the level of industrial safety of one of the oil refineries of PJSC ANC Bashneft. Each of the installations in this production refers to hazardous objects and requires special attention. This is due to the fact that the equipment is drawn a large number of hazardous substances belonging to different hazard classes. To hazardous substances are not only the main components of processing, but also auxiliary and intermediate products of the technological chain. The assessment of industrial safety is an important part of production and avoids the occurrence of a fire or explosion, and in the event of an emergency - minimize the negative consequences. To assess the level of industrial safety, it is proposed to consider all the equipment of technological installations in aggregate as a whole. The article uses an integrated assessment of the plants and production facilities of the oil refinery in terms of the risk of a fire or explosion. The indicators of all installations and industries as a whole are considered, the shares of commodity production and direct technological installations of the oil refining process are established. In work the method of an estimation of the generalized parameter of safety of an oil refining factory by means of a curve of Lorentz is applied. As a criterion of industrial danger of each installation, the total amount of hazardous substances circulating in apparatus and pipelines is adopted. A quantitative criterion is determined - the Gini coefficient. The coefficient values are calculated taking into account the tank farm of commodity production and without it. It is shown that hazardous substances are distributed according to technological installations with moderate unevenness - the Gini coefficient was 0,441. The installations with the maximum danger from the point of view of the quantity of explosive and fire hazardous substances are determined.
