Evaluation method for domino accident prevention of petrochemical storage tank area

Abstract

The invention provides an evaluation method for domino accident prevention of a petrochemical storage tank area. The evaluation method comprises the steps of constructing a hierarchical structure of an occurrence possibility of a domino accident cause of a tank area unit, and quantifying the domino accident cause through hierarchical calculation; constructing a grading guide and scoring criteria of fuzzy operation membership degrees, and effectively combining a fuzzy analytical hierarchy process with an LEC process to solve the problem of difficulty in quantifying an L value with an expert experience method during occurrence of an domino accident under the combined action of multiple factors; determining a danger level of the domino accident through a fuzzy hierarchy-LEC process formed by combination, and clearly determining key points of domino accident prevention of the storage tank area unit; and finally according to an evaluation result, analyzing the domino accident cause and proposing targeted suggestions and prevention measures for avoiding the blindness of domino accident prevention and ensuring safety running of the petrochemical storage tank area.

Description

technical field [0001] The invention relates to the field of accident prevention in petrochemical storage tank farms, in particular to an evaluation method for domino accident prevention in petrochemical storage tank farms. technical background [0002] As a storage device for various raw materials and products used in the production process, the petrochemical storage tank area has a wide variety of storage materials and most of them are flammable and explosive chemicals. The explosion hazard environment in the area is complex. Once an initial fire and explosion accident occurs in the petrochemical storage tank area, it is easy to trigger the domino effect, forming a situation of "connecting tanks and a sea of ​​fire", threatening the life and property safety of enterprises and affecting the stable development of society. [0003] At present, the research on the domino effect is relatively mature, but most of the studies by domestic and foreign scholars focus on the research...

Problems solved by technology

[0002] As a storage device for various raw materials and products used in the production process, the petrochemical storage tank area has a wide variety of storage materials and most of them are flammable and explosive chemicals. The explosion hazard environment in the area is complex. Once the initial accident of fire and explosion occurs in the petrochemical storage tank area, it is easy to trigger the domino effect, forming a situation of "connecting tanks and a sea of ​​fire", threatening the life and property safety of enterprises and affecting the stable development of society.

[0003] At present, the research on the domino effect is relatively mature, but most of the studies by domestic and foreign scholars focus on the research on the probability model, transmission route and risk calculation of the domino effect. It is difficult to quantitatively reflect the disaster-causing factors of the accident, and it is also impossible to determine the risk level of the domino accident in the research unit. It cannot provide the decision-making basis for the prevention of domino accidents for enterprises, which is not conducive to the safety management of enterprises.
