Triethylene Glycol is commonly used in the Oil and Gas Industry for gas dehydration. In most cases it is placed into contact with natural gas, and strips the water out of the gas.

Parameters:

CAS No.: 112-27-6

Purity: 99%

Standard Compliance: REACH, EPA

Glycol molecules bind to water molecules, preventing the formation of hydrate crystals. This lowers the temperature at which hydrates form, ensuring smooth production even in cold environments.

Parameters:

CAS No.: 111-76-2

Purity: ≥99.0

It has a low viscosity, a low pour point and relatively high flash point making it ideal for deepwater exploration. It is widely used as a non- aqueous base fluid in an invert emulsion drilling mud in the upstream oil and gas industry.
