Nitech™ NRU (Nitrogen Rejection) Technology
Nitrogen Rejection Units (NRU) selectively removes nitrogen from a gas. In practice, cryogenic plants have the highest methane recovery rate (about 98%) of any of the nitrogen rejection technologies and have become standard practice for large-scale projects where they achieve economies-of-scale.
Nitech™ NRU Technology
An advanced cryogenic NRU technology
Nitech™ NRU Nitrogen Rejection (NRU) technology, developed by our business partner BCCK Engineering, enables producers to profitably recover once by-passed reserves, regardless of nitrogen content. Additionally, it can increase project profitability through integrated NGL extraction and helium recovery. NitechTM NRU technology is an economical, effective, environmentallyfriendly, and highly efficient process to remove high concentrations of nitrogen from inlet flow rates as little as 50 million m³ per year up to 2500 million m³ per year.
The major advantages of Nitech™ NRU process are;
1. Only three major components;
2. No cryogenic rotating equipment;
3. The same efficiency of traditional cryogenic processes;
4. A less complex, more reliable and lower cost design.
Proven and Applied Technology
More than 20 Nitech™ NRU systems have been installed, where they have generated extra revenue streams from;
Unconventional gas, naturally occuring low-BTU gas streams, enhanced oil recovery, nitrogen rejection/removal, CO2 removal, helium recovery, skidded LNG plants, and oxygen removal.
Nitech™ NRU Vs. other cryogenics technologies
We can prove that the Nitech™ NRU technology can be up to 15% less expensive on both OPEX and CAPEX in comparison to other cryogenic technologies.
BCCK installed this Nitech™ NRU facility in North Dakota including integrated NGL extraction for associated gas in an adjacent fire flood.

Additional advantages of the Nitech™ process;
- Small footprint (about 6x18 meters for a 200-500 million m³ annualplant).
- Minimum operator attention required with average runtimes in excess of 99%.
- Recompression horsepower requirements which compare favourably with even the most efficient conventional cryogenic process designs.
- Much lower power and compression requirements than non-cryogenic technologies.
- Significant Nitrogen reduction Inlet nitrogen contents ranging from 5% to 70% can be reduced to 1%, depending on pipeline requirements.
- Possibility for integrated NGL extraction including ethane recovery in excess of 90%
- Possibility for integrated Helium recovery with helium recovery as high as 99%.
- CO2 tolerant with no treating required beyond the capability of readily available amines.
