Hazard and Operability (HAZOP) Study for LPG Bullet at Heat Treatment Line with BLEVE Dispersion Modelling Using CAMEO

Abstract

In this paper, the toxicity-impacted distance of LPG is predicted using the Areal Locations of Hazardous Atmosphere (ALOHA) chemical dispersion model. The model incorporates data on the chemical characteristics of the material, local weather patterns, and release circumstances to predict the sensitive regions that might be toxically impacted by an LPG leak. The nodes are selected for processes plants so that each may have a specific design objective that is relevant, and they are frequently shown on piping and instrumentation diagrams (P&IDs) and process flow diagrams (PFDs). The chemical industry is increasingly using the hazard and operability (HAZOP) research as a tool to identify safety issues in existing facilities as well as plants that are currently being developed or built. The goal of The HAZOP research technique emphasizes the safety component while the LPG bullet is built as a horizontal above ground vessel. The explosive risk associated with LPG is considerable due to its high flammability and (BLEVE) boiling liquid expanding vapour explosion potential. This explosion might result in fatalities and significant property damage; therefore, we used the (HAZOP) hazard operability research approach to identify all pertinent possible risks. We also provided the necessary control measures to lessen or completely eliminate the danger of fire and explosion.
