Abstract

There are PFD(Process Flow Diagram) and P&ID(Piping and Instrument Diagram) for designing and managing chemical process efficiently. They provide the operation condition and equipment specifications of chemical process, but they do not provide the reliability of chemical process. Therefore, in this study, Reliability Flow Diagram(RFD) which provide the cycle and time of preventive maintenance has been developed using Directed Graph Analysis methodology. Directed Graph Analysis methodology is capable of assessing the reliability of chemical process. It models chemical process into Directed Graph with nodes and arcs and assesses the reliability of normal operation of chemical process by assessing Directed Graph sequential. In this paper, the chemical process reliability transition according to operation time was assessed. And then, Reliability Flow Diagram has been developed by inserting the result into P&ID. Like PFD and P&ID, Reliability Flow Diagram provide valuable and useful information for the design and management of chemical process.

화학공정을 효율적으로 설계 및 관리하기 위한 도면으로 공정흐름도와 공정배관 계장도가 있다. 본 도면들은 공정의 운전조건 및 설비에 대한 정보를 제공하지만 공정이 정상적으로 운전할 신뢰도는 제공하지 못한다. 따라서 본 연구에서는 유향그래프 분석기법을 이용하여 화학공정의 예방점검 정비주기 및 시점을 결정하기 위한 정보를 제공할 수 있는 신뢰도흐름도를 개발하였다. 유향그래프 분석기법은 화학공정이 정상적으로 작동할 가능성을 평가할 수 있는 기법으로써 노드와 아크를 사용하여 화학공정을 유향그래프로 모델화하고, 이 유향그래프를 순차적으로 해석하여 화학공정의 신뢰도를 평가하는 기법이다. 본 연구에서는 운전시간에 따른 화학공정의 신뢰도를 분석하고, 그 결과를 공정배관 계장도에 삽입하여 신뢰도흐름도를 개발하였다. 본 신뢰도흐름도는 화학공정의 기본 도면인 공정흐름도, 공정배관 계장도와 마찬가지로 화학공정의 설계, 예방점검 등 설비관리에 효율적으로 이용될 수 있을 것이다.
