Why should you use membrane nitrogen generators?

ByGlobal Lab Supply

There are many manufacturers that require nitrogen gas for their manufacturing processes. However, the high costs associated with purchasing nitrogen from industrial gas suppliers and the inconvenience of waiting for the gas to be delivered can take a toll on your bottom line. With an onsite membrane nitrogen generator, you can achieve cost savings and other efficiencies that can lower your ongoing nitrogen costs by up to 90% depending on the application. Here’s how membrane nitrogen generators work and how you can get a quality system installed for your application.

How Does a Membrane Nitrogen Generator Work?

Membrane Nitrogen Generators use a hollow porous fibre to separate the nitrogen molecules from the other gases in ambient air, like oxygen, carbon dioxide, water vapor, and argon. The molecules from the stream of compressed air flowing into the generator are separated using high pressure (selective permeation). Faster gases permeate the walls quickly and are released back into the atmosphere, while the nitrogen is focused for use.

Benefits of a Membrane Nitrogen Generator

There are many advantages for having an onsite membrane type nitrogen generator installed, the biggest benefit being that you can lower your ongoing nitrogen costs by up to 90% depending on the application.

Following are benefits and features of Membrane Nitrogen Generator at Global Lab Supply a   nd how they can improve efficiency in a variety of applications.

  • An independent onsite supply of nitrogen, which means freedom from the industrial gas supplier and their long-term contracts and ever escalating nitrogen costs
  • Fast Return on Investment (ROI); typical ROI can be expected within six to 18 months
  • Fully automatic systems for on-demand operation; you only produce nitrogen as required
  • Extremely reliable
  • Easy, low cost maintenance
  • Minimal space requirements
  • Membrane type nitrogen generators can be housed in modified sea containers for system mobility or portability
  • Eliminate wasteful venting of nitrogen gas that’s associated with bulk liquid nitrogen tanks
  • Produces nitrogen purities from 95% to 99.5%; match nitrogen purities to the actual nitrogen purity requirement of your application
  • Nitrogen flow capacities are available from 40 SCFH (1 m3/hr) to 200,000 SCFH+ (5,600 m3/hr+)
  • Nitrogen discharge pressures to 300 psig (20 barg) without booster compressors
  • High pressure systems to 20,000 psig (1,360 bar) available

Features include touchscreen controllers with the following capabilities:

  • oxygen analyzer
  • air in pressure
  • nitrogen discharge pressure
  • low nitrogen purity alarm
  • low nitrogen pressure alarm
  • maintenance advisory
  • optional purity control setting (up to three purities)
  • optional remote monitoring, controlling and communications capability
  • optional nitrogen flow monitoring
  • optional off spec. gas vent

Turnkey systems engineered, assembled, and installed to specification
