Reliable Risk Estimation in the Risk Analysis of Chemical Industry Case Study: Ammonia Storage Pressurized Spherical Tank

摘要

This paper presents a general overview of a procedure for the evaluation of individual and societal risk connected with accidental release of toxic and/or flammable substances. In this study, methodology and procedure for a probabilistic safety assessment are outlined. Evaluation of individual and societal risk is the key point of the probabilistic safety assessment in chemical industry. The steps of the presented procedure were applied to a pressurized spherical tank for ammonia storage in order to estimate reliable risk of its casual rupture with different magnitude of the tank damage. The case study results demonstrate that further development in the probabilistic safety analysis of chemical industries has to be done, in order to develop more effective and rapid procedures for complex risk estimation with reliable and realistic values of probabilities.
