Description
Summary:The process safety field is constantly changing and evolving, so it is important to periodically assess new developments that affect each of the various types of safety equipment. Pressure relief and flare systems are examples of equipment systems that have experienced recent and ongoing changes. This article focuses primarily on three areas of activity in pressure-relief systerns: new calculation methods; updates to regulatory codes and standards; and lessons learned from safety events at chemical process industries facilities. To illustrate potential problems associated with pressure-relief systems and possible mitigation options, the article also discusses the findings from a study, conducted by the authors' employer, of pressure-relief equipment at a petrochemical facility.
