Triethylene glycol (TEG), with the chemical formula C6H14O4, is a colorless, odorless, and water-soluble liquid. It belongs to the glycol family and is derived from ethylene oxide.
The compound is renowned for its hygroscopic nature, which makes it excellent for absorbing and retaining moisture. TEG exhibits unique chemical properties that make it valuable for various applications.
It has a high boiling point, low vapor pressure, and low volatility, which are essential for its use in heat transfer and dehydration processes. Additionally, TEG is miscible with water and many organic solvents, further enhancing its versatility.
In the oil and gas industry, TEG plays a crucial role in natural gas dehydration. It is used in glycol dehydration units to remove water vapor from natural gas streams, preventing pipeline corrosion and hydrate formation. TEG’s hygroscopic nature makes it effective in this process.
