Abstract

A systematic approach to find out the probability of Ammonia tank failure was adopted and a consequence analysis in case of accidental Ammonia release from refrigerated ammonia storage tanks was made. The study revealed that construction of a concrete bund wall around the tanks is not justified. Instead, it would be adequate to upgrade the safety in the common dyke around the tanks by adopting additional conventional methods.
