Marine Nitrogen Generators


NOXERIOR has an experience of more than thirty years with the design and manufacturing of nitrogen generators based on air separation by either Pressure Swing Adsorption (PSA) or hollow-fibre membranes.

Having a profound knowledge of both processes, the hollow-fibre membrane technology has been considered the preferred solution for the NITROMEM® Marine Nitrogen Generators:

  • Continuous process compared to intermittent PSA process. No moving parts = increased reliability & system availability,
  • Reduced system footprint, no need for feed air dryer and feed air receiver. Smaller dimensions of the membrane nitrogen generator,
  • Higher nitrogen discharge pressures up to 12 bar(g) without need for nitrogen booster,
  • Stable nitrogen production capacity up to 430 Nm3/h compared to falling production capacities of PSA generators at increasing feed air temperatures (more than 20% loss of capacity from 20 to 35 °C in comparison to equivalent membrane systems), and
  • Lower nitrogen dew point equal or better -70 °C / -94 F.
