  • Flare gas measurement flow meter applications - Air and Climate

    Flare gas measurement flow meter applications

    Oil wells almost always produce natural gas (“associated gas”) along with the petroleum. In many cases, it is uneconomical to process due to heavy contamination. As a consequence, this gas is combusted, “flared” or simply vented as-is during upset conditions in the process. Newly updated EPA regulations like 40 CFR Part 60 Subpart OOOO (also known as Quad O) as well as the new RSR MACT rule for refineries, requires oil & gas companies to report the flare gas emitted to our atmosphere....
