Water & wastewaterDigester gas flow

In the anaerobic decomposition process, organic matter is converted into stable solids and energy-rich gas, mainly methane (60%) and carbon dioxide (40%). A combustible hydrocarbon of high fuel value, methane can serve as a fuel for in-plant heat exchangers, blower engines or other systems, marketed to the local industrial community, or burned off.

Challenge

Safe and reliable flow measurement is essential in the collection, disposal or re-use of methane gas. Because methane is highly combustible, flow instrumentation must be certified for operation in these hazardous locations.
