Biomethane – the renewable natural gas.

700-5000 m3/h, reliable, compact

ETW’s business is innovation and a secure future for energy supplies.

At sites with renewable production of gas from biogas, sewage gas or landfill gas we offer an alternative to onsite power generation: purifying the gases to the quality of natural gas according to the alternating pressure adsorption process.

Advantages of the ETW PSA technology:

  • - short cycles, which means compact plant construction
  • - simple plant construction and extremely high operating availability
  • - long-lasting adsorbents and reliably rotating valves = low maintenance costs and high operating availability
  • - long operating period between maintenance measures
  • - high level of gas purity attainable (< 0.5% CO2)
  • - no methane emissions
  • - tried and tested technology with many customer references
  • - purification capacity: 700 – 5000m³ raw gas/hour
