Study On Safety Evaluation System Of L - CNG Filling Station

At present, with the development of CNG gas station and LNG filling station in the domestic, L-CNG gas station has also been a great deal of attention and achieved great development. Due to the current domestic L-CNG gas station has not formed a complete system of safety evaluation system, so L-CNG gas station safety comprehensive evaluation exists some problems of studying not in-depth and the vacancy of safety evaluation method and system, safety evaluation is necessary to ensuring the normal operation of L-CNG gas station. According to the above problems, the article is going to evaluate the safety of L-CNG gas station.The focus of this article, the first is how to establish a relatively complete L-CNG gas station safety evaluation index system, only the establishment of a complete safety evaluation index system, fully considering the possible each factor affecting the L-CNG gas station security, to make the building safety evaluation index system has certain persuasive and practical significance.According to the evaluation index system of L-CNG gas station, this article mainly used two kinds of evaluation method based on extension synthesis assessment and fuzzy comprehensive evaluation, and the evaluation results that finally getting will be compared, finding out the advantages and disadvantages of two kinds of evaluation methods and their respective applicable scope, providing effective reference value for the L-CNG gas station safety assessment.Finally, the paper summarizes all kinds of accident consequence model analysis of L-CNG gas station, analyzing the LNG leakage, fire and explosion hazards and consequences, and put forward the safety precautions of L-CNG gas station, providing effective guarantee for safe operation of L-CNG gas station.
