What is triethylene glycol TEG used for in oil and gas? (CAS 112-27-6)

CAS 112-27-6 Triethylene glycol (TEG) is a liquid chemical compound with the molecular formula C₆H₁₄O₄ or HOCH₂CH₂CH₂O₂CH₂OH. Its CAS number is 112-27-6. TEG is recognised for its hygroscopic properties and its ability to dehumidify fluids. It is miscible with water and soluble in ethanol, acetone, acetic acid, glycerine, pyridine and aldehydes. It is only slightly soluble in diethyl ether and is completely insoluble in oil, fat and most hydrocarbons.

What is triethylene glycol TEG used for in oil and gas?

Triethylene glycol TEG is produced commercially as a by-product of the oxidation of ethylene at high temperatures in the presence of a silver oxide catalyst. This is followed by the hydration of ethylene oxide to produce monoethylene glycol, diethylene glycol, triethylene glycol, and tetraethylene glycol.

The oil and gas industries use TEG to dehydrate natural gas, as well as other gases, including CO₂, H₂S and other oxygenated gases. Other industrial uses include as an adsorbent and absorbent, a functional fluid in both closed and open systems, an intermediate, a processing aid in petroleum production, and a solvent. TEG is also used in the production of many consumer goods, including antifreeze, automotive care products, building and construction materials, cleaning products, furniture care products, fabrics, textiles and leather goods, fuels and related products, lubricants and greases, paints and coatings, personal care products, and plastics and rubber products.
