Applications:
It is used by oil and gas industries to dehydrate natural gas. It may also be used to dehydrate other gases like CO2, H2S and other oxygenated gases.
As a dehumidifying agent in air-conditioning units. It is also used to make chemical intermediates such as plasticisers and polyester resins.
As an additive in hydraulic fluids, and TEG is also used as a solvent in many applications, including as a selective solvent for aromatics, and a solvent in textile dying.
