Research on FTA of Fire and Explosion in the Crude Oil Gathering-transport Combination Station

摘要

Based on FTA of safety-system engineering and analysis of risk or hazard factors of technological process and materials, it is determined of the fault tree factor table of crude oil gathering-transport combination station and established of the fire and explosion fault tree. By means of Boolean algebra simplification, the minimum path sets of the system are achieved. Then the occurrence probability of the fault tree top event is given together with the three importance-degree analysis of the basic event. Through the fault tree analysis, the paper discusses qualitatively and quantitatively the main factors of fire and explosion in combination station, and some corresponding improvement measures are proposed. The analysis result can provide theoretical direction for design, construction, management and maintenance of crude oil gathering-transport combination station.
