The Catalytic Methane Abatement System (CMAS)

Our flagship product, the Catalytic Methane Abatement System (CMAS), utilizes platinum-based catalysts to convert methane gas into CO2 and water vapor. Engineered for outdoor installation, CMAS units are capable of operating at low back pressures typically found in surface casing vents, oil storage tank vents, production casings, pneumatic control devices, gas dehydrators, and more.

Key Features:

  •  Efficiency: High-efficiency catalytic conversion
  •  Operation: Suitable for low flow rates and pressures
  •  Temperature: Reaction occurs at temperatures ranging from 250-500°C (500-950°F), well below methane's auto-ignition temperature of 700°C (1300°F)
  •  Self-Sustainability: Once initiated, the reaction is self-sustaining, requiring no external power source
  •  Installation: Easy installation with "Plug & Play" functionality
  •  Durability: Designed for outdoor use in extreme weather conditions
  •  Scalability: Available in small, medium, and large sizes to accommodate various flow rates. Units can be clustered together for higher flow rates.
  •  Optional Heat Recovery: Larger units come with an option for heat recovery

Proven Performance:

Metan's CMAS units have undergone rigorous testing and validation by reputable organizations such as the Saskatchewan Research Council (SRC), Petroleum Technology Alliance Canada (PTAC), and Canadian Emissions Reduction Innovation (CERIN). Field tests have demonstrated impressive destruction efficiencies, with results exceeding regulatory requirements.

  •  SRC Field Test: The Saskatchewan Research Council (SRC) conducted a field test on a suspended well in Alberta, demonstrating a destruction efficiency of 92%. View Test Report AI-EES (
  •  PTAC and CERIN Field Test: Another field test was conducted on an operating oil well in central Saskatchewan, funded through PTAC and CERIN. Complete report here AI-EES (

Environmental Impact:

Methane (CH4) is a potent greenhouse gas with a Global Warming Potential (GWP) significantly higher than that of carbon dioxide (CO2). Over a 20-year timeframe, methane's GWP is approximately 80 times greater than CO2, making it a major contributor to climate change.

By converting methane into CO2 and water vapor, our CMAS units help reduce the net impact on global warming. While CO2 is also a greenhouse gas, its GWP is significantly lower than methane, especially over longer timeframes.
