Nitrogen Rejection Unit (NRU)
Sparco Engineering designs and delivers advanced Nitrogen Rejection Units (NRU) for the efficient separation of nitrogen from natural gas streams. These systems are essential for upgrading low-BTU gas and ensuring it meets pipeline quality specifications.

How It Works

The NRU operates based on cryogenic distillation technology. The incoming natural gas is cooled to extremely low temperatures where nitrogen and methane are separated due to their differing boiling points. The result is a high-purity methane gas stream ready for pipeline transport and a nitrogen stream safely vented or recovered for other uses.

Key Benefits

• High-efficiency nitrogen separation achieving up to 99.9% methane recovery.
• Compact, skid-mounted modular design for quick installation.
• Fully automated process control with minimal operator intervention.
• Energy-efficient operation with optimized refrigeration cycles.
• Compliant with international gas processing standards.
