We’re seeking qualified EPC contractors for a comprehensive revamp of a legacy gas compression/gas-lift system with the following scope:
Key Issues:
In summary
Key Issues:
- Compressor runs at >100% speed due to lower MW gas – Re-wheel or trim impellers
- Severe rotor fouling (iron sulfide/salt) – Chemical wash vs. coatings?
- Condensate-induced pressure drops – Compact exchangers vs. pipeline redesign
- What’s the most cost-effective way to extend life 10+ years?
- Critical pitfalls to avoid with legacy turbine-compressor packages
- Recommended vendors for mid-range custom revamps (not full OEM replacement)
In summary
- Centrifugal compressor upgrades: Re-wheel for lower MW gas, dry gas seals, vibration control (iron sulfide/salt fouling).
- Condensate management: Replace corroded exchangers (E-306A/B/C), optimize gas-lift network.
- DCS migration: Mark-II → Mark VIe + Emerson DeltaV.
- Corrosion mitigation: GRE/3LPE piping, chemical injection.
- Prior experience with 20+ yr-old turbomachinery in oil/gas.
- API 617/672 compliance.
- Ability to phase works (minimize downtime).
