Triethylene glycol (TEG) is a clear, odorless, and non-volatile liquid with a high boiling point and excellent hygroscopic properties. It is widely used as a natural gas dehydrating agent, efficiently removing water vapor to prevent pipeline corrosion and hydrate formation. Beyond gas processing, TEG functions as an antimicrobial fogging agent in HVAC systems, a solvent and plasticizer in coatings, resins, and cosmetics, and as a heat-transfer fluid. Its stability, low toxicity, and versatility make it essential across multiple industries.#TriethyleneGlycol #TEG #GasDehydration #IndustrialSolvent #HeatTransferFluid #AirSanitization #Plasticizer #MaterialScience
