Overview


Challenges
  • When natural gas (NG) is emitted to the atmosphere, its impact over 20 years as a greenhouse agent is 80 times higher than CO₂
  • Recovery and valorization of gases otherwise vented by turbomachinery are major challenges facing industry
Results
  • The dedicated recovery system handles process gas coming from machinery loops and seals
  • The versatile system can be tailored to any pressure in any oil and gas plant vent and flare recovery
  • Typical payback period is just 2–4 years
Case study details

A third of global NG emissions is attributable to the extraction and transportation of fossil fuels. The main hydrocarbon release sources of a typical turbocompression unit are: centrifugal compressor dry gas seal (DGS) primary vent, process gas trapped inside the centrifugal compressor loop that is vented during shutdown, and the pneumatic starting system where pressurized process or fuel gas is used as motive fluid.

Baker Hughes offers a compact compression system designed specifically to capture NG vent flows—for recycling into the compression process or valorization as fuel gas. It's easy to implement, whether as a retrofit or for new installations, has a short payback period, and is proven in the field.
