벤젠 옥외탱크저장소 누출사고 시 누출속도를 고려한 수용설비 설계에 관한 연구

Abstract

The possibility of leakage accidents has been being increased since the number of hazardous chemical substances, tanks and facilities has been increased. In a typical example, the leakage accident from an oil storage tank occurred in April 2014 and the total loss is KRW 18 billion. After this accident, many companies and organizations have begun to develop a mitigation system to minimize the loss of the leakage accident. The aim of this study is to design the mitigation system for handling leakage accidents. In this study, the Benzene tank is selected to verify the performance of a mitigation system. In order to design this system, the leakage velocity and quantity according to time should be analyzed. The basic concept of the mitigation system is that the leakage fluid of Benzene is moved to a reserve tank and this is transferred to a spare tank by a pump for avoiding the overflow of a reserve tank. Based on the mathematical simulation, the optional pump capacity is investigated by the consideration of the overflow. Throughout this study, the optional design of a case study is suggested and this study can play a critical role to provide a guideline for designing this system.
