Vent / Flare Scrubbers

WellFlex Vent Scrubber helps you run a environmentally responsible gas flare system by helping keep liquids out of your flare stack. It is a two-phase separator that scrubs free liquids from your vent gas system prior to entering the relief and blow-down lines in your flare system. The unit is typically used downstream of gas treating equipment and can handle a wide range of flow rates.

How It Works

WellFlex scrubber inlet gas first encounters the inlet diverter, which causes initial separation of vent gas from liquid. The heavier liquid descends while the vent gas rises. Liquids exit the bottom of the vessel and the natural gas exits the top to flare system.
