HAZARD EVALUATION USING ALOHA TOOL IN STORAGE AREA OF AN OIL REFINERY

Praveen Patel, Nagendra Sohani

Abstract: During accident process equipment, storage area and associated accessories can release hazardous material very quickly and insignificant quantity to spread out in dangerous cloud throughout the plant site and local communities. Areal location of Hazardous Atmosphere (ALOHA) is a software design specially in responding to hazardous material releases. Aloha models assess key hazards such as toxicity, flammability, thermal radiation and explosion over pressure related to chemical releases in the event of either fire or explosion. This paper covers actual damage distances due to flammable liquids and gases of oil refinery stored in finished product section in different pressure vessels. Catastrophic rupture of the individual product has been described in imaging worst scenario and damage distances for heat loads has been calculated. The output of ALOHA Tool provide the worst case scenario consequences results on plant and nearby local community and summarizes the useful fact for onsite emergency plan of oil refinery.
