Oxygen generators for biogas and biomethane production

Atlas Copco’s OGP oxygen generators are more cost effective than bottled/liquid oxygen and offer the required purity with a high flow capacity, making them perfect for your biogas and biomethane production.

Atlas Copco’s OGP oxygen generators offer the required purity with a high flow capacity, making them suitable for a range of applications.

With a full range of oxygen generators to choose from, Atlas Copco brings you the right supply of oxygen to meet your specific needs and optimise your production process at the same time.

Why do you need oxygen generators for your application?

The reason for not using air is that it would introduce 78% N2 which in turn would lower the calorific value of the biogas, measured by the Wobbe index. The CH4 concentration could fall below 50%, which is too low for the gas engine and RNG upgrading plant. N2 is also difficult and costly to remove downstream.

In short, choosing O2 over air prevents nitrogen dilution of biogas, without affecting the digestion process and H2S elimination efficiency.

Also, removing H2S using oxygen is often much cheaper and more sustainable than other methods of desulphurisation like ferric dosing.  

Why use our oxygen generators for your biogas and biomethane production?

High purity oxygen supply

The OGP Series includes oxygen concentrations from 90% to 95% and provides a cost-efficient oxygen solution for biogas and biomethane applications. 

Atlas Copco's OGP oxygen generator uses Pressure Swing Adsorption technology to isolate oxygen molecules from other molecules in compressed air to leave high purity oxygen at the outlet of the generator.

Onsite oxygen generation

  • Lower operating costs. No rental charges, transport expenses or bulk user evaporation losses (up to 80% more cost-effective vs. delivered; depending on purity, gas and electrical cost).
  • Greater safety. No safety hazards when handling high-pressure cylinders.
  • Higher productivity.  By saving the time that is normally spent on changing tanks, you will ensure that your application runs continuously and without much attention from the operator. 
  • Better control. Generating your own oxygen means no more ordering, changing and running out of bottles. There will also be no more liquid deliveries to remote locations interrupting production, and you no longer have to deal with suppliers' unpredictable price increases.
  • Non-stop availability. 24 hours a day, 7 days a week.
  • Reduced footprint.  Minimising the visits of trucks for oxygen delivery and any related CO2 emissions.

Ready to use solution

  • Only requires a supply of dry compressed air.
  • Plug-and-play.
  • No specialist installation or commissioning.
  • Fully automated and monitored including.
  • Oxygen sensor as standard.
  • Service-friendly.

Cost-effective

  • Low operating expenses.
  •  No additional costs such as order processing, refills and delivery charges.
  • Limited maintenance costs.

Exceptional reliability

  • Robust design.
  • Continuous availability (24 hours a day, 7 days a week).
  • Potential risk of production breakdown due to gas.
  • Running out is eliminated.
