Pressure relief systems protect against catastrophic accidents caused by equipment overpressure. Despite their importance, pressure relief systems do not always receive adequate attention during design, construction, and maintenance. This is often due to the application of outdated analysis and calculation methods. The American Institute of Chemical Engineers` Design Institute for Emergency Relief Systems (DIERS) has developed new methods to design relief systems for runaway reactions and for two-phase, vapor-liquid relief. The Occupational Safety and Health Adminstration`s Process Safety Management Regulation recognizes these new methods as {open_quotes}good engineering practice{close_quotes}. Application of these new methods has shown that a number of existing relief systems are inadequate. This article describes an approach to systematically modernize existing pressure relief systems using DIERS technology. 23 refs., 12 tabs.
