Our products:

Biogas upgrading systems

Feed gas:
  • Biogas
Product gas:
  • Biomethane
  • CO₂-rich gas
Separation technologies:
  • Membrane
  • Adsorption (PSA)
Biomethane application:
  • Injecting into the national gas grid
  • Using as vehicles fuel (CNG/LNG)
How It Works
(CH₄ > 50%; CO₂ < 50%)
  • From organic waste
  • From energy crop
  • From landfill gas
  • From wastewater treatment plant
UP TO 99,95%
(RECOVERY >99.95%)
  • Injecting into the national gas grid
  • Using as vehicles fuel (BioCNG)
  • Using as vehicles fuel (BioLNG)
Biomethane application
Biomethane has similar characteristics to natural gas, in addition, its combustion characteristics (calorific value, Wobbe number, etc.) can be adapted to the conditions of local natural gas grid.

Biomethane can be used for the same purposes as natural gas:
Electricity generation;
Heat generation;
Transport (CNG, LNG).

Biogas upgrading plant

Designed by UGS Europe

  • Upgrade biogas to biomethane, depending on the requirements/needs of the consumer;
  • Operational reliability and resistance to failures (proven design solutions);
  • Quick installation and extensions (module container setup);
  • Simple operation and automation of the plant;
  • Fast start-up of system;
  • Delivery time <8 months;
  • Long service life of the plant;
  • Low operating costs.
  • 1 year mechanical warranty with optional prolonged guarantees

Our equipment delivers dependable ROI to your project. We can design and build your system to achieve the optimum balance of Carbon Intensity and Operational Effectiveness.

Typical biogas upgrading processes are well-known, but not always well-executed. Maximizing biogas process performance requires expertise. This is the UGS Europe difference.

How we are working
Analysis of consumer needs and project objectives to find the optimal solution.
Engineering & Design
Engineering and design of the proposed solution including the specifics of the project.
Start up
Supply of equipment, installation and start-up of the plant. Monitoring the achievement of the declared indicators.
After-sales service to ensure high efficiency and reliability of the equipment.
