Flare Header Modification / Re-Route – Gas Processing Plant

Evaluation of flare header modification

As part of a client’s project to reroute the existing underground flare piping to a newly constructed, above ground header system and add relief valves to existing flare system, Vega Oil and Gas Consulting evaluated the relief devices and new header system.

• Performed back-pressure analyses for all PSVs discharging to flare based on re-configured piping
• Proposed changes to several PSV types based on total back-pressure analyses
• Re-evaluated the existing global relief scenarios and added relief valves as required
• Proposed necessary changes to prevent liquid pockets in flare headers
• Designed new Knock Out Drum
