There are two main types of glycols, ethylene glycol and propylene glycol with propylene glycol available in industrial and food grades. Detergents Ingredients Database - EU Ecolabel. Ethylene glycol helps keep your car?s engine from freezing in the winter and acts as a coolant to reduce overheating in the summer. [5]. It is used in a wide variety of industrial applications, including as a compound in the manufacture of polyurethane plastic, in … The glycol solution will absorb water from the wet gas. OPTIMIZATION OF TRIETHYLENE GLYCOL (TEG) DEHYDRATION IN A NATURAL GAS PROCESSING PLANT ... dehydration process used to attain pipeline sales specifications and field requirements [2], [4]. Ethylene glycol is used in the natural gas industry to remove water vapor from natural gas before further processing, in much the same manner as triethylene glycol (TEG). Hydrate inhibition. When aerosolized it acts as a disinfectant. The ether being relatively unreactive. TRIETHYLENE GLYCOL is a ether-alcohol derivative. Print Share on: Evidence.
