Automating HAZOP analysis of batch chemical plants: Part

specializing in the production of large, medium and small concrete mixers, concrete mixing stations, stabilized soil mixing stations and other equipment. It is a heavy industry enterprise integrating R & production and sales.

Automating HAZOP analysis of batch chemical plants:

Aug 20, 1998  The central problems to be solved in the automation of HAZOP analysis for batch process plants are: (i) generalizing the continuous process HAZOP methodology for batch processes, and (ii) developing an overall knowledge representation framework that would facilitate the organization and representation of diverse types of knowledge such as product recipes, tasks, and subtasks.

Petri net-Digraph models for automating HAZOP analysis

Jan 01, 1996  The Petri net-Digraph model for representing batch process provides such a framework. Using this framework, a model based system for automating HAZOP analysis of batch chemical processes, called Batch HAZOPExpert, has been implemented in the object-oriented architecture of Gensym's real-time expert system G2.

Automated HAZOP revisited - ScienceDirect

Oct 01, 2017  Use of automated HAZOP for batch analysis and procedure safety implies that component models must include modelling for normal operation in order to investigate a full sequence of plant states. For example, hot distillation products may be transferred to a tank that contains a residue of gasoline or water, giving a rapid phase transition explosion.
