PSV and Flare Analysis – Fractionation Plant
Evaluation of relief device and system sizing for a gas fractionation plant
As part of a plant debottlenecking effort, Vega Oil and Gas Consulting evaluated the existing relief device, Knock Out Drum (KOD) and flare sizes relative to the higher plant throughput rate.
- Reviewed existing relief valve analyses and flare header analysis
- Re-evaluated rate dependent overpressure scenarios at higher throughput rate including inlet and outlet pressure drop analyses
- Determined “pinch” reboiler duties associated with various column to estimate realistic relief rates
- Re-evaluated KOD and flare radiation
- Proposed mitigation options to resolve deficiencies to meet higher throughput rate
