The Catalytic Methane Abatement System “CMAS” is a Patented Devise that is a Solution to Surface Case Vents with build-ups and leaks, Facility Tools and Instrumentation exhaust, and Production Wells, to reduce GWP from raw Methane venting, by over 85%. The CMAS Units convert Methane to C02 and Water Vapor, via a Flameless Catalytic process. The CMAS Units are intended to operate at low gas pressure (minimum of 0.25 PSI), and operate over a low flow range across the product line of 2.5 to 75 CFH. Additionally, once the CMAS is operational, no on-site power is required to operate.
