TEG (Tri-Ethylene-Glycol)

TEG is used by the oil and gas industry to “dehydrate” natural gas. It may also be used to dehydrate other gases, including CO2, H2S, and other oxygenated gases. It is necessary to dry natural gas to a certain point, as humidity in natural gas can cause pipelines to freeze, and create other problems for end users of the natural gas. Triethylene glycol is placed into contact with natural gas, and strips the water out of the gas. Triethylene glycol is heated to a high temperature and put through a condensing system, which removes the water as waste and reclaims the TEG for continuous reuse within the system.

Triethylene glycol is well established as a relatively mild disinfectant toward a variety of bacteria, influenza A viruses and spores of Penicillium notatum fungi.[4] However, its exceptionally low toxicity, broad materials compatibility, and low odor combined with its antimicrobial properties indicates that it approaches the ideal for air disinfection purposes in occupied spaces.
