Gas Sensing System Employing Raman Scattering

Industries that utilize natural gas, gasifier syngas, biogas, landfill gas, or any type of fuel gas can benefit from knowing the composition of a fuel gas mixture in real-time. Natural gas, the most common fuel, can have significant variation in hydrocarbon composition in areas supplied by multiple sources. The “opportunity fuels” such as biogas and landfill gases, also have significant variation in quality, and operators often use natural gas as a backup fuel.  There is a need for a sensing system that is able to quickly and reliably identify, characterize, and determine the concentration of the various gases in a gas mixture.
