Safety Analysis of Naphtha Flash Separator Using the DYLAM Methodology

Abstract

There is a growing need for safety analysis of chemical processes. Risk analysis techniques capable of evaluating dangerous transient conditions together with the reliability of the protective systems need to be devised. Analyses a flash separator used for the raw separation of a naphtha stream into its volatile and liquid constituents from the point of view of its safe operation by the use of the DYLAM methodology. Details a newly developed dynamic simulator of the transient behaviour of the separation operation. This simulator, coupled with the DYLAM algorithm, depicts at any moment the behaviour of the process stream in the drum and highlights the time thresholds which, if exceeded, may result in an accident owing to an uncontrolled evolution of the operation.
