RISK ASSESSMENT MODEL FOR HYDROGEN TRANSFER SYSTEM
Fire or explosion is a major concern in hydrogen applications due to hydrogens wide flammability range, low ignition energy, and flame speed. This paper describes the risk Assessment process for investigating potential accidents and the results of the process in terms of measures that reflect both the frequency and the severity of the accident during the transfer of Hydrogen. Hazard and Operability (HAZOP) study is used as the first step in risk assessment modeling to identify the potential hazards. Pasquill-Gif-ford Gaussian Dispersion Model is used to identify the consequences of Hydrogen release and hazard zones. TNT model is used to predict the strength of the blast wave produced by an unconfined vapor cloud explosion (UVCE) as a function of distance from the vapor cloud. TNO model is used to calculate the fireball diameter and height during a boiling liquid vapor explosion (BLEVE) to determine the catastrophic rupture of a pressure vessel. All the models are physically verified and the safe distances are determined for the chosen scenarios.
