Glycol (TEG) 

tegren-5-.jpegNatural gas dehydration can be accomplished by a glycol system which removes most of the water vapor from the gas. This is a requirement for most gas sales contracts because it prevents hydrates from forming when the gas is cooled in the transmission and distribution systems. 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.

Another reason to meet this specification is it prevents water vapor from condensing and creating a corrosion problem within pipelines and equipment. These systems can go by many names like TEG dehydration, glycol dehydration plant, glycol system. However,  the parts on these systems are all relatively the same.
