Research on application of hazard analysis and control technology for integrated process

Process hazard analysis and control technology emphasize on using systematic approach to identify the hazardous,and take necessary measures to eliminate and reduce the hazards,or mitigate the accident consequences caused by the hazards.At present,the global energy and chemical enterprises all adopt characterized process hazard analysis and control technology for process safety management.In this study,an integrated process hazard analysis and control technology which included HAZOP,LOPA and Bow-Tie analysis was introduced.Taking a furnace as an example,the hazards existing in the equipments were fully analyzed and identified by HAZOP,the sufficiency of protection layers was determined by LOPA,and through Bow-Tie method,the efficient activities ensuring the designated control measures or emergency measures are still effective were identified.Therefore,the integrated process hazard analysis and control technology could change the process safety management of the enterprise from experience-based management system to systematic management system,so as to effectively avoid the occurrence of major process safety accident,and improve risk management level of enterprises.
