EVENT AND FAULT ANALYSIS OF ETHYLENE RELEASE FROM ETHYLENE VAPORIZATION UNIT

Abstract

Event and fault analysis is very important method to find out failure event in the system. And also determine the failure rate & reliability of the system. Fault tree analysis is a systematic, deductive and probabilistic risk assessment tool which elucidates the causal relations leading to a given undesired event. Quantitative fault tree (failure) analysis requires a fault tree and failure data of basic events. An event tree begins with an initiating event, such as a component failure, increase in temperature/pressure or a release of a hazardous substance. Event tree analysis is based on binary logic, in which an event either has or has not happened or a component has or has not failed. It is valuable in analyzing the consequences -arising from a failure or undesired event. By event tree analysis, we can easily determine out-come of consequence during process. In my dissertation report, I determine event & fault tree analysis of ethylene release in ethylene vaporization unit. And study the whole process system and identify all failure events. And also determine qualitative & quantitative evaluation of failure events and determine failure frequency & reliability of the system by the help of fault tree analysis. And in event tree analysis, I identify all initiating event & classify the hazards outcomes. And determine quantitative evaluate all consequence during process
