Abstract:
Cryogenic natural gas processing plants sometimes include:
• Natural Gas Liquids extraction
• Nitrogen Rejection
• Optionally: Helium recovery
These three processes have been implemented at many locations worldwide. This paper will introduce the three independent processes and will show how their integration can bring value to customer. An innovative integration will be presented, illustrated with the example of a recent FEED study of a multi-train gas processing plant performed by Air Liquide. Benefits are energy savings and reduced capital expenditure through optimized multi-train strategy. Optimization of reliability and availability, critical for such multi-train projects, will also be introduced.
