PPM® creates a relational database of safety-related information associated with pressure relief systems, fire systems, and vapor disposal systems. This centralized data repository contains not only the specifications, but also the reasoning behind the specifications.

• Relational database architecture for integration with other engineering and plant information management systems
• Systematic identification of all potential overpressure scenarios associated with each piece of equipment
• Calculation of required relief rates, including two-phase relief scenarios based upon both the American Institute of Petroleum (API) and Design Institute of Emergency Relief Systems (DIERS) methodologies
• Calculations can be based on either built in thermodynamic packages or external simulators
• Calculation of relief device capacities (pressure safety, valves, rupture disks, and/or conservation vents), including two-phase releases based on API or DIERS methodologies
• Calculation of relief device inlet and outlet piping pressure losses
• Evaluation of overall vapor disposal systems (relief headers, knockout drums, flare tips, etc.)

Process safety information (PSI) at your fingertips
PPM® encapsulates processing relief data into a platform that you can continue to use. Since process information is continually updated, process engineers are fully informed on the limitations of each piece of processing equipment and why, ultimately saving on re-engineering efforts and future Process Hazard Analysis findings. PPM® also increases flexibility in response to market changes, minimizing cost overruns.
