Relief System Designer Skill

Purpose

The Relief System Designer Skill designs pressure relief systems including PSV sizing, relief load calculations, and disposal system design per API standards.

Capabilities

  • Relief scenario identification
  • Relief load calculations
  • PSV sizing (API 520/521)
  • Flare header hydraulics
  • Blowdown system design
  • Two-phase relief calculations
  • Reactive systems relief
  • Relief device selection

Usage Guidelines

When to Use
