본 논문의 목적은 Ethyl Benzene 플랜트의 공정에서 과압 현상이 Column 상부의 반응폭주 및 화재 폭발의 원인이 되기 때문에 안전장치시스템의 신뢰도가 압력방출밸브가 요구하는 안전건전성수준으로 설계되어 있는지를 정량적으로 분석한 것이다. 압력방출밸브의 요구시 실패확률은 일반신뢰도 자료 조사결과를 근거로 하여 안전장치시스템에 대한 안전건전성수준의 목표등급을 SIL3으로 설정하였고, 이에 대한 PFD를 1.00E-3에서 1.00E-4로 결정하였다. 신뢰도 모델의 구축 및 결함수 분석기법을 이용하여 SIS의 요구시 실패확률에... -

공학적인 방안으로는 설계시 요구되는 적정 신뢰도를 유지하는 것이므로 적어도 소방펌프에 요구되는 신뢰도수준으로 설계되어야 한다. 즉 SIS(Safety Instrumented system)에 요구되는 신뢰도수준인 안전건전성수준(SIL; Safety integrity level)에 적합한가의 유무를 PFD를 활용하여 정량적으로 파악하는 것이다. 공통원인고장을 고려한 소방수 공급설비에 대한 신뢰도분석 결과 계통작동요구시 실패확률(PFD: Probability of failure on demand), 즉 계통 이용 불능도는 3.80E-3이므로 규정목표인 SIL5의 범주 안에 들어있지 않아...
