More than 24 Nitech™ NRUs have successfully been installed, where they have generated extra revenue streams from:

  • Naturally occurring low-BTU gas streams
  • Unconventional gas
  • Coal Mine Methane
  • Enhanced oil recovery

The major advantages of Nitech™ NRU process are;

  • Only three major components;
  • No cryogenic rotating equipment;
  • The same efficiency of traditional cryogenic processes;
  • A less complex, more reliable and lower cost design

G.I. Dynamics also provides proven high efficient integrated processes in combination with nitrogen rejection:

  • NGL extraction
  • Helium extraction
  • Liquefaction plant
