BTEX Eliminator

The BTEX Eliminator is a heat exchanger condensing system used to capture and recycle BTEX and V.O.C. from the regenerator still column. Condensed liquids are collected and transferred to storage, while the residual V.O.C. vapors are sent to the burner or to compression.

BTEX Eliminators are used to capture benzene, toluene, ethylbenzene and xylene (BTEX) and other volatile organic compounds (VOCs) from the still column of triethylene glycol (TEG) regenerators. They also reduce operating costs by recovering sellable condensates and using VOC vapors for burner fuel. We offer two main unit styles: an air-cooled exchanger and a shell-and-tube exchanger, which cools the gas with glycol for cold-climate applications. The BTEX Eliminator is available in various sizes, compatible with a wide range of glycol regenerator sizes.

Key Benefits


  • Efficiently removes up to 95% of BTEX and other VOCs when operated in accordance with recommended practices
  • Stainless-steel construction for added durability
  • Reduces BTEX and VOC odors
  • ASME code stamped blowcase removes condensed liquids


  • Easy field installation for fast startup
  • No electric power required
  • Uses residual VOC vapors for burner fuel savings
  • Recovers fugitive condensate for additional revenue
  • In-stock inventory of pre-assembled units allows fast delivery, installation and startup


  • Added assurance of a warranty on our manufactured products that runs 12 months from startup or 18 months from delivery, whichever comes first
  • Prompt, professional service, support and spare parts from local technicians in or near every major oil & gas producing region in the U.S. and numerous areas around the world

How it Works

The mixture of hydrocarbons and water that leave the still column are routed through a heat exchanger where liquid is condensed and sent to a blowcase. As the blowcase level rises, a level switch is tripped, which opens a valve to send the liquids to storage or for sale. The residue gas that does not condense in the heat exchanger can be sent to a regenerator fuel gas line or to an optional vapor recovery unit (VRU), helping to minimize operating costs and reduce air emissions.
