All equipment and piping systems should be protected when internal or external pressure can exceed the design conditions of the system. Whether due to an emergency, upset condition, operational error, instrumentation malfunction, fire, or other credible scenario, the proper processes and systems must be in place to quickly and efficiently respond to these scenarios.

Our professionals complement their experience with our proprietary PSVTool© software to accomplish the design, evaluation, revalidation, and consequence modeling of pressure relief and flaring systems in a cost-efficient manner.  Our pressure relief and flare studies document relevant assumptions and intermediate calculations, allowing for a thorough investigation of specific scenarios to identify potential improvements.

Our studies follow the applicable industry adopted guidelines and specific codes, such as:

  • American Petroleum Institute (API)
    • API RP-520 Parts I & II
    • API RP-521
  • American Society of Mechanical Engineers (ASME)
    • ASME Sec. VIII, Div. I
    • ASME Sec. I
  • Design Institute for Emergency Relief Systems (DIERS) methods
BakerRisk provides a full range of pressure relief and flare analysis service offerings, including the following:
  • Pressure relief rate calculations
  • Flare and venting system analyses
  • System backpressure on closed relief systems
  • Dynamic flare header hydraulics
  • Flare tip pressure drop calculations
  • Vapor dispersion of atmospheric relief
  • Thermal radiation from flare stack or ground flares
