초록

현대 화학플랜트 및 석유 가스 산업 시설은 다양한 잠재위험으로 인하여 위험물질의 누출 및 화재가 빈번히 발생하고 있다. 그 중 특히 화재는 직접적인 화염의 접촉 또는 복사열로 인하여 인명피해는 물론 건물, 설비에 대한 피해 발생으로 domino effect가 발생하여 2차, 3차 피해까지도 발생하기도 한다. 따라서 본 연구에서는 발생가능한 화재를 파악하여 사고피해영향과 빈도를 낮추어 화재 위험성을 관리하는 FRA(Fire Risk Assessment)기법의 절차를 제시하였으며, 사고피해영향으로 화염의 직접적인 접촉과 복사열로 인한 주요건물(제어실, 창고, 변전소)의 물리적 특성이 변형되는 시간을 고려하였다. 사례연구를 통하여 수행한 FRA기법으로 국내외 화학공장의 위험성을 경감시킬 수 있었으며, Protection 설정을 통한 사고의 빈도와 피해영향의 감소를 정량적으로 파악할 수 있었다.

Chemical plants and oil gas refinery facilities are intrinsically vulnerable to industrial hazards, such as explosion or fire. Especially, the fire is extremely dangerous to facility structures and plant personnel because of direct flame, radiant heat and smoke. In addition, it has the ripple effect of destroying infra-structures and polluting the environment. In an effort to tackle these potential industrial risks, the procedure of FRA techniques in chemical plants were investigated. The main focus was put on the time variation of physical properties of the main building, i.e. control rooms, warehouses and electrical substations, from a direct flame contact and radiant heat. The deformation of a building due to fire was monitored and modeled with respect to time variable. A variety of case studies, domestic and abroad, was tested in the model to verify the FRA procedure. The developed model was proven to be highly effective to reduce the possible risks at chemical plants. An accurate accident frequency prediction and damage quantification was made by the developed model.
