Nitech™ Nitrogen Rejection Unit

 

BCCK’s Nitech NRU technology allows natural gas companies to recover once-bypassed reserves profitably, regardless of nitrogen gas concentrations. Also, when implemented in the mining industry, the Nitech process is instrumental in reducing the levels of methane within coal mines.

 

The Nitech process is an economical, effective and highly efficient way to remove excess nitrogen from gas streams. While most nitrogen removal systems are economical only for volumes of gas 30 MMSCFD or larger, Nitech removes high concentrations of nitrogen from as little as 3 MMSCFD. The Nitech process works equally well in larger applications – even with inlet gas flow at 250 MMSCFD or higher. 

 

BCCK constructed its first Nitech NRU in Mist, Oregon in 1994.  In the 15 years since, we’ve constructed Nitech systems in Texas, Alabama, Pennsylvania, Illinois, Colorado, Kansas and Wyoming, and we have several more systems currently under construction.

Benefits of Nitech nitrogen extraction:

 

• Low capital cost – only three major components
• Low power consumption – typically less than 15 kW
• Simple design – minimal operator attention; average runtimes over 99%
• No cryogenic rotating equipment
• Small footprint – approximately 100’ x 100’
• Compression horsepower much lower than non-cryogenic NRU options
• CO2 tolerant – approximately 250 ppm without additional treatment
• Nitrogen contents from 5% to 70% reduced to as low as 1%
• High efficiency – hydrocarbon recovery typically in excess of 99%
• Environmentally friendly – emits no non-methane VOCs
• Quick restart
• Cold restart from short shutdowns
• Online and on spec – just restart associated compression
• Integrated NGL extraction with high NGL extraction efficiencies (up to 90% ethane recovery)
• Integrated helium extraction with high helium recovery
