Overpressure Protection in the Process Industry: A Critical View provides a practical and pragmatic guidance for anyone dealing with overpressure protection in the process industry. The book explains the background of complicated international codes and regulations, offering a pragmatic and practical approach on how these codes can be interpreted for specific cases. The book also gives a critical view on these codes and regulations and where they do or don't make sense, along with the challenges in some instances, including technical and practical argumentations. Finally, the book covers specific problem areas and sizing methods when using safety relief devices as overpressure protection, such as how to handle installation, backpressures, blowdowns, the 3% rule, types of chatter and other destructive forces in relief devices. - Helps readers understand and apply codes and regulations in a pragmatic way - Provides sizing guidance on most overpressure scenarios and how to approach them in a pragmatic way - Creates awareness about the possible dangers of overpressure, especially in aging plants and how modifications on the process can jeopardize the overpressure protection - Addresses non-regulated types of overpressure protection in a process plant, such as the overpressure and vacuum protection of low-pressure storage tanks and tank blanketing

The book is a guide for Layers of Protection Analysis (LOPA)practitioners. It explains the onion skin modeland in particular, how it relates to the use of LOPA and the needfor non-safety instrumented independent protection layers. Itprovides specific guidance on Independent Protection Layers (IPLs)that are not Safety Instrumented Systems (SIS). Using theLOPA methodology, companies typically take credit for riskreductions accomplished through non-SIS alternatives; i.e.administrative procedures, equipment design, etc. Itaddresses issues such as how to ensure the effectiveness andmaintain reliability for administrative controls or“inherently safer, passive” concepts. This book will address how the fields of Human ReliabilityAnalysis, Fault Tree Analysis, Inherent Safety, Audits andAssessments, Maintenance, and Emergency Response relate to LOPA andSIS. The book will separate IPL’s into categories such as thefollowing: Inherent Safety eliminates a scenario or fundamentally reduces a hazard Preventive/Proactive prevents initiating event from occurring such as enhancedmaintenance Preventive/Active stops chain of events after initiating event occurs but beforean incident has occurred such as high level in a tank shutting offthe pump. Mitigation (active or passive) minimizes impact once an incident has occurred such as closingblock valves once LEL is detected in the dike (active) or the dikepreventing contamination of groundwater (passive).

Current industry, government and public emphasis on containment of hazardous materials makes it essential for each plant to reduce and control accidental releases to the atmosphere. Guidelines for Pressure Relief and Effluent Handling Systems meets the need for information on selecting and sizing pressure relief devices and effluent handling systems that will maintain process integrity and avoid discharge of potentially harmful materials to the atmosphere. With a CD-ROM enclosed containing programs for calculating flow through relief devices, effluent handling systems, and associated piping, the book offers an important collection of state-of-the-art technology for safely relieving process equipment of such conditions as overpressure, overtemperature and/or runaway reactions. It provides information for two-phase and compressible gas flow to select and size pressure relief devices, piping, and effluent handling equipment, such as gravity separators, cyclones, spargers, and quench pools.
