Abstract:
This paper outlines the quantitative risk assessment (QRA) for a fast-fill CNG station. Methane (CH4) is the major material used in this plant. Methane is a flammable chemical that can lead to fire and explosion. A systematic procedure including a detailed HAZOP study of the entire station has been used. Fault tree analysis (FTA), event tree analysis (ETA) technique and historical data have been used to identify the most credible scenarios obtained from HAZOP studies and to calculate their probabilities. Consequence analysis of the credible scenarios has been carried out by using PHAST 6.5 software package containing several models for performing consequence analysis through risk assessment. The risk which has been estimated in term of fatality is monitored by the F-N curve and iso-contours. These results form the basic inputs for the risk management decisions
