MEG, or monoethylene glycol, has a wide range of uses, including as an antifreeze and coolant, a heat transfer fluid, a chemical intermediate, and in the production of polyester fibers and resins.

Here’s a more detailed breakdown of MEG’s applications

Industrial Applications:

  • Antifreeze and Coolant: MEG is a primary ingredient in automotive antifreeze and engine coolant formulations, preventing freezing in cold temperatures and overheating in hot conditions. 
  • Heat Transfer Fluids: MEG’s excellent thermal conductivity and heat transfer properties make it suitable for transferring heat energy in industrial processes, including heating, cooling, and refrigeration systems. 
  • Chemical Intermediate: MEG serves as a building block in the synthesis of various chemicals and compounds, including diethylene glycol (DEG), triethylene glycol (TEG), and ethylene glycol ethers. 
  • Polyester Production: MEG is a crucial raw material in the production of polyester fibers and resins, which are used in textiles, packaging, and other industries. 
  • Textile Industry: MEG is used as a humectant in fiber processing, facilitating the production of high-quality polyester and ensuring efficient fiber spinning. 
  • Solvent: MEG can serve as a solvent in the manufacture of inks, dyes, and other chemical products. Natural Gas Dehydration: In the oil and gas industry, MEG is used for natural gas dehydration to remove water vapor from natural gas streams. 
  • Hydraulic Fluids: MEG is employed as a hydraulic fluid additive in hydraulic systems and equipment to improve lubrication, reduce friction, and prevent corrosion. 
  • De-icing agent: MEG is used in the formulation of deicing fluids for aircraft and runways at airports to prevent the accumulation of ice. 
  • Humectant: MEG is used as a humectant in some agrochemical formulations to help retain moisture and prevent drying out of granular or powdered products.
