An Automatic System for HAZOP Analysis

HAZard and Operability (HAZOp) analysis is the study of systematically identifying every conceivable process variable deviation, its abnormal causes and adverse hazardous consequences in a chemical plant. HAZOp analysis is a difficult, time-consuming, and requires labor-intensive activities. An automated HAZOp system can reduce the time and effort involved in a HAZOp review, make the review more thorough and detailed, and minimize or eliminate human errors. Towards this goal, an expert system, called HAZOpEN, has been proposed in this article. In this approach, HAZOp knowledge is divided into process-specific and process-general knowledge-base. A framework allows this two components to interact during the analysis to address the process specific aspects of HAZOp analysis while maintaining the generality of the system. The important features of HAZOpEN and its performance on two industrial case studies are mentioned. HAZOpEN has been implemented in an object-oriented framework using C++ language of programming.
