TEG (Triethylene Glycol)

TEG is an important non-volatile industrial solvent. It is also useful in the dehydration of gases, manufacture of insecticides and in the synthesis of some organic derivatives. Pure TEG is useful in the production of plasticizers for cellophane, glue, cork, powdered ceramics and some plastics. TEG is a component in the formulation of some pigments, printing dyes, inks and pastes. It is also used for air fumigation.

The most common process in use in the Gas Processing Industry today is the TEG Gas Dehydrator. The dehydration process contacts dry tri-ethylene glycol (TEG) with wet gas to absorb the water from the natural gas in a glycol contactor tower. The contactor tower contains trays or structured packing to maximize the contact between the wet gas and dry glycol. The rich glycol containing the absorbed water is sent to a glycol reconcentration system which regenerates the wet glycol by filtering, and heating to 204°C (400°F). This purifies the wet glycol by eliminating the water in the form of steam, and the regenerated glycol is then pumped and recycled to the inlet of the Glycol Contactor to contact the wet gas again.

We have been supplying TEG for Natural Gas industries for more than 15 years around South East Asian region.
