Project Synopsis

Perform relief valve sizing for a compression system used in fertilizer manufacturing.

Project Summary


Process Engineering Associates, LLC (PROCESS) was subcontracted by the client, a detail engineering design firm, to size relief valves located on a compressor system for the ultimate client, a fertilizer manufacturer.  As part of this project, the following tasks were accomplished:

  • Performed sizing calculations and provided documentation for 6 pressure safety valves (PSVs)
  • Performed hydraulic calculations to adequately size inlet and outlet piping for the new PSVs
  • Developed process level specification sheets for the new PSV devices.

PROCESS utilized its licensed commercial simulation software’s hydraulics package and chemical/physical component database along with its proprietary in-house relief device capacity computer program, along with calculations based on the guidelines in American Petroleum Institute (API) Standards 520 and 521, to determine the pressure relief requirements for this application.

PROCESS supplied the client with customized pressure relief device (PRD) sizing documentation packages that included safety device calculations and relief valve equipment datasheets that could be used to obtain quotes from vendors.  PROCESS also suggested specific relief devices represented in vendor literature.
