Glycol Dehydrators

Glycol Dehydration is the industry standard equipment for removing water from natural gas to meet pipeline pr design specifications

CROFT's TEG Model

Removing most of the water vapor from the gas is required by most gas sales contracts because it prevents hydrates from forming when the gas is cooled in the transmission and distribution systems. Additionally, it prevents water vapor from condensing and creating a corrosion problem.

Croft Production Systems, Inc. has developed a glycol dehydration design that combines the best practices through the industry. CROFT will properly size and sell a system to meet your needs. For efficiency gains and environmental consideration, CROFT promotes this baseline product with upgraded features like BTEX, Burner Management Systems (BMS), and sensors with control kills.

How it Works

Most sales contracts in the United States call for 7 lbs/MMcf. In colder climates, sales requirements of 3 to 5 lbs/MMscf are common.

They utilize a structured packed tower or bubble cap contact tower. Wet gas enters the base of the tower and flows upward through the bubble caps. Dry glycol enters the top of the tower and works its way through a series of trays. There are typically 6 to 8 trays for a contact tower unless it is structured-packed or random-packed. Most glycol dehydrators use trimethylene glycol, which can be heated to 340-400° F in the reconcentrator and work with gas temperatures to 120° F.

TEG Applications

  • All standard design components are included in the system.
  • Extra filtration for better glycol regeneration.
  • Proper high temp paint for the high heat components
  • Higher-temp insulation designed for ambient conditions.
  • Designed for lower heat flux on firetube.
  • Custom client options can be added to standard design .
