Abstract

Quantitative risk analysis has been performed for a pervaporation process for production of high test peroxide. Potential main accidents are explosion and fire caused by a decomposition reaction. As the target process has a laboratory scale, the consequence is considered to belong to Category 3. An event tree has been developed as a model for occurrence of a decomposition reaction in the target process. The probability functions of the accident causes have been established based on the frequency data of similar events. Using the constructed model, the failure rate has been calculated. The result indicates that additional safety devices are required in order to achieve an acceptable risk level, i.e. an accident frequency less than $10^{-4}/yr$. Therefore, a layer of protection analysis has been applied. As a result, it is suggested to introduce inherently safer design to avoid catalytic reaction, a safety instrumented function to prevent overheating, and a relief system that prevents explosion even if a decomposition reaction occurs. The proposed method is expected to contribute to developing safety management systems for various chemical processes including concentration of hydrogen peroxide.

초고농도 과산화수소 제조를 위한 투과증발 공정의 정량적 위험성 분석을 수행하였다. 잠재적 주요 사고는 분해반응에 따른 폭발 및 화재이며 실험실 규모일 때 사고결과는 카테고리 3에 속하는 것으로 판단된다. 대상공정에서 분해반응이 일어나는 과정을 사건트리 형태로 모델링하고 사고원인들의 확률함수를 유사사건 발생빈도 자료를 근거로 설정하였다. 구축된 모델을 사용하여 사고율을 계산한 결과, 수용 가능한 위험수준, 즉 사고빈도가 $10^{-4}/yr$ 이하가 되려면 추가 안전장치가 필요한 것으로 파악되었다. 이를 위해 방호계층분석을 적용한 결과, 촉매반응을 막기 위한 본질적 안전설계, 과열을 막기 위한 SIF (safety instrumented function), 그리고 분해반응이 일어나더라도 폭발로 이어지지는 것을 막는 릴리프 시스템이 요구되었다. 제안된 방법은 과산화수소 농축을 포함한 다양한 화학공정의 안전관리시스템 개발에 기여할 수 있을 것으로 기대된다.
