Risk evaluation method for fires and explosions at tank storage areas at petrochemical decks

Abstract

The invention provides a risk evaluation method of fires and explosions at tank storage areas at petrochemical decks. The risk evaluation method comprises the following steps: establishing a risk evaluation index system of a tank storage area at a petrochemical deck, and confirming main risk factors; calculating the weight of each risk factor of the tank storage area at the petrochemical deck according to the risk evaluation index system so as to provide an acceptable risk criterion which is suitable for loading and unloading operations at the tank storage area at the petrochemical deck; selecting a fire accident probability calculating method for the tank storage area at the petrochemical deck; establishing a fire damage model according to accident consequences; confirming the frequency and the consequence of every assumed accident so as to obtain theoretical personal risk values; classifying acceptable risk levels of the tank storage area at the petrochemical deck based on the acceptable risk criterion. The risk evaluation method disclosed by the invention overcomes the subjectivity of the conventional level classification and is adopted for quantitative risk calculation and level classification on the actual risk management process of the tank storage area at the petrochemical deck, so that the efficiency of safety management is improved.

Description

technical field [0001] The invention relates to the field of risk management of petrochemical wharfs, in particular to a fire and explosion risk assessment method for a storage tank area of ​​a petrochemical wharf. Background technique [0002] Due to the large scale of petrochemical terminals, often exceeding one million tons, there are often situations where multiple dangerous chemicals are loaded and unloaded at the same time. It is an important storage facility for petrochemical wharves. It generally stores flammable and explosive hazardous substances. During loading and unloading operations, the fire and explosion of storage tanks is one of the most important dangerous and harmful factors. If the liquid leaks, it is possible to form a liquid pool on the surface of the solid or liquid. For flammable liquids, a pool fire is likely to occur when encountering an ignition source. For volatile liquids, leakage may volatilize and form a vapor cloud. There is a danger of explo...
