Abstract

The ALOHA program was used to propose an improvement plan for antifouling agents by reflecting the effects of toxicity, overpressure, and radiant heat around the storage tank of dangerous goods manufacturers. The ALOHA program was used to analyze the damage effects of isooctane on the toxicity, overpressure, and radiant heat of isooctane for the surrounding effects of the isooctane leakage accident, which is the first class of petroleum. As a result, it was analyzed that the toxicity was 117m in the area above the PAC-2 concentration, the overpressure was 114m in the range of 1 psi or more, and the radiant heat was 1,900m in the range of 2kW/m2 or more. Therefore, it is necessary to implement a performance-oriented dike design by applying a risk assessment reflecting the physical and chemical characteristics of dangerous substances that reduce and store the amount of octane in the antifouling agent by installing an dike for each storage tank of isooctane at a minimum distance of 38m from the center of the tank.

이 연구는 ALOHA 프로그램을 이용하여 위험물제조소등의 저장탱크 주변의 독성, 과압 및 복사열의 영향을 반영하여 방유제의 개선방안을 제안하는 것을 목적으로 한다. 제4류 제1석유류인 아이소옥테인 누출사고에 따른 영향에 대하여 주변영향을 ALOHA 프로그램을 이용하여 아이소옥테인의 독성, 과압, 복사열에 대한 피해영향을 분석하였다. 그 결과 독성은 PAC-2 농도 이상인 지역이 117m 이하였고 과압은 1psi 이상의 범위가 114m이며 복사열은 2kW/m2 이상의 범위가 1,900m로 분석되었다. 따라서 아이소옥테인의 저장탱크의 방유제는 탱크 중심부에서 최소 38m 이상의 거리를 두고 설치하여 과압과 복사열의 영향을 최소화하고 아이소옥테인의 저장탱크별로 각각 방유제를 설치하여 방유제 안의 옥탄의 수량을 줄이고 저장하는 위험물의 물리·화학적 특성을 반영한 위험성 평가를 적용하여 성능위주 방유제 설계를 실시할 필요가 있다.
