Glycol dehydration is a liquid desiccant system for the removal of water from natural gas and natural gas liquids (NGL). It is the most common and economical means of water removal from these streams. [1] Glycols typically seen in industry include triethylene glycol (TEG), diethylene glycol (DEG), ethylene glycol (MEG), and tetraethylene glycol ...
TEG is used by the oil and gas industry to "dehydrate" natural gas.It may also be used to dehydrate other gases, including CO 2, H 2 S, and other oxygenated gases. [2] It is necessary to dry natural gas to a certain point, as humidity in natural gas can cause pipelines to freeze, and create other problems for end users of the natural gas.
Ethylene glycol is widely used to inhibit the formation of natural gas clathrates (hydrates) in long multiphase pipelines that convey natural gas from remote gas fields to a gas processing facility. Ethylene glycol can be recovered from the natural gas and reused as an inhibitor after purification treatment that removes water and inorganic ...
Most types of ethylene glycol antifreeze contain a few percent of diethylene glycol, present as a by-product of ethylene glycol production. DEG is an important industrial desiccant . It absorb water from natural gas , minimizing the formation of methane hydrates , which can block pipes.
A natural-gas processing plant in Aderklaa, Austria. Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing contaminants such as solids, water, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), mercury and higher molecular mass hydrocarbons to produce pipeline quality dry natural gas [1] for pipeline distribution and final use.

After authorities reopened parts of Altadena for the first time since the Eaton fire, residents returned to a grim checkerboard of destroyed homes next to others that were largely spared.
An FDA-approved medication already used to treat people who have type 2 diabetes and chronic kidney disease may also help lower their stroke and heart attack risk, a new study has found.
Natural gas burning on a gas stove Burning of natural gas coming out of the ground. Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes.
