Abstract
For a Liquified Petroleum Gas(LPG) station, the reliability analysis, such as Fussell-Vesely importance, risk decrease factor and risk increase factor, was carried out and the risk ranks of events were determined. In order to confirm the degree of the risks identified in the reliability analysis, the quantitative risk analysis was done for the equipments which had the large values of risk ranks. As a result of the importance analysis for the LPG station, the external event was identified as the most riskful event. The defect of construction structure and the pipe corrosion were riskful as well. The result of quantitative risk analysis showed that the length of 46.3 meters were estimated to damage the process equipments by the thermal flux from the catastrophic rupture of storage tank in Boiling Liquid Expanding Vapor Explosion.
본 연구에서는 LPG 충전소에 대하여 Fussel-Vesely 중요도와 RDF 및 RIF 중요도를 수행하여 위험성 등급(Risk Rank)을 설정하였다 설정된 위험성 등급에서 위험성이 가장 큰 장치 및 설비에 대하여 정량적 위험성 분석을 수행하였다. LPG 충전소에 대한 중요도 분석결과 외부사고가 가장 위험하다고 확인되었으며, ekda 으로 구조물 결함과 파이프 배관의 부식의 위험등급이 높았다. 정량적 위험성 분석 결과로는 LPG 충전소 저장탱크의 완전히 파열하였을 경우에 대한 BLEVE의 경가 발생하였을 경우에 복사열에 의해 공정 설비에 손해를 입히기에 충분한 거리는 46.3m로 분석되었다.
