ABSTRACT

Chemical storage tank leakage in petrochemical wharf is a serious economic, environmental and safety problem. Risk assessment is an effective way to identify chemical storage tank hazards and provides a guide for accident prevention in petrochemical wharf enterprises. Based on the characteristics of chemical storage tank zone, this paper proposes a real-time relative risk assessment method. Firstly, the disastrous consequences of chemical storage tank leakage are analyzed and quantified. Then, the set-pair analysis is employed to construct a relative risk assessment model. Finally, a computer program is developed to simulate chemical storage tank leakage and achieve a real-time risk assessment. A case study is conducted to verify the effectiveness of this method. The results show that the relative risks of different chemical storage tanks will change with the variation of storage quantity. The proposed method and developed program are valid for assessing risks of chemical storage tank leakage in petrochemical wharf, and may be helpful to manage chemical storage tank hazards of petrochemical wharf enterprises and to provide corresponding safety precaution as well.
