Analysis about Risk Changes before and After Inspection of 23 Storage Tanks and Research on the Inspection Strategy

摘要

Inspection of storage tanks has been taken less seriously over past years, as not required by laws. Therefore, projects adopting risk evaluation technology of atmospheric-pressure storage tanks are rarely seen. Characterized by large volume and high risks, hazardous chemicals often lead to serious accidents. This paper evaluates risks of 23 atmospheric-pressure storage tanks of 100 thousand m~3 of a storage house. Supposing the storage house implemented inspection within 5 years or 10 years, this paper studies risk changes before and after the inspection. It puts forward an inspection strategy to guarantee long term safety of storage tanks according to the risk analysis outcome.
