Vent Scrubber

The Vent Scrubber helps you run a safer and more 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 stream 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. Versions for both onshore and offshore applications are available.

Key Benefits

  • Expedited production drawings available as early as 4-5 business days for faster planning
  • Single well or multi well designs available along with full pad well designs
  • Robust skid design and commitment to service help bring operations online quickly
  • Cost-effective maintenance
  • Installation and commissioning of the units to facilitate and speed startup
  • Industry-leading delivery to speed startup

How it Works

The production stream 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. With the optional skid-mounted system, the accumulated liquid is removed via a pneumatic level control and pump.
