Biomethane – the renewable natural gas.
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. The core component of these purification plants is the DWA module from Xebec Inc., Montreal, Canada.
Advantages of the Xebec/ETW DWA 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
