Influence of Chlorine Induced Corrosion and Temperature of Exothermic Reaction on Failure of Methyl Isocyanate (MIC) Storage Tanks

摘要

The aim of the present work was to know the facts of Methyl Isocyanate (MIC) gas leakage and burst of its storage tank. The failure of the tank was evaluated based on the Tresca, von Mises criteria, Weibull criteria. The significance of chlorine induced corrosion and temperature derating factor were recognized using Taguchi techniques. The bursting pressure of the storage tank was highly dependent on the temperature derating factor and the crack depth. The reasons for the failure of experimental storage tanks used in the present work would satisfy the causes for the leakage of Methyl isocyanate gas and failure of the storage tank during the Bhopal gas disaster.
