메탄올 저장탱크의 누출사고 시 누출속도를 고려한 방유제 설계에 관한 연구

Abstract

Methanol, a typical hazardous chemical, is being used in industrial sites for more materials such as solvents and biodiesel. However, methanol is highly toxic to the human body and flammable, which can cause fire or explosion, which requires attention during storage and handling. Due to the hazards and risks of methanol, leakage prevention measures and extent of damage effects are studied that have been strengthened and specialized in storage and handling facilities. However, most of the research focuses on qualitative measures such as early detection, evacuation and control of the accident. For this reason, various accident simulations and safety device modeling are required to quantitatively calculate leakage volume and extent of damage before methanol leakage accident and to establish and verify accurate countermeasures.

In this study, the leakage rate is calculated according to the diameter and height of the leak source in the storage tank of methanol, which is used as a material in the biodiesel process, and the leakage trajectory of methanol is used to calculate the leakage velocity.

The research method calculates the leakage trajectory by comparing the actual operation pressure of the methanol storage tank with the various operation pressure, and evaluates the validity of this Regulation and presents the plan for future actions. As a simulation tool, MATLAB is used to calculate differential spinning techniques effectively.
