  • Di-ethyleenglycol Wikipedia

    Net als glycol verlaagt di-ethyleenglycol het vriespunt van de oplossing en verhoogt het het kookpunt, en wel in hogere mate dan met glycol. Het is een van de grondstoffen voor de productie van polyesterharsen en een intermediair product bij de synthese van andere organische verbindingen, zoals morfoline en 1,4-dioxaan.

  • The Impact of Stripping Gas Flow Rate on Triethylene

    Glycols are used primarily to dehydrate gas streams [12]. Glycols are the favourite solvents because they have low solubility in natural gas, high hygroscopic characteristics, low vapor pressure and low volatility [13]. The glycols mostly used include ethylene glycol (EG), diethylene glycol (DEG) and triethylene glycol (TEG).

  • Glycol Solution an overview ScienceDirect Topics

    Proper maintenance of the glycol solution is critical for trouble-free operation of the dehydration process. Chemical analysis of the solution can often prevent or identify the cause of operating problems. Analyses are typically made for water, pH, lower glycols, hydrocarbons, foaming tendency, and inorganic salts (particularly chlorides).

It does NOT include glycol ethers derived from propylene glycol, dipropylene glycol, or tripropylene glycol.

  • Glycol Gas Contactor an overview

    Glycols used for dehydrating natural gas are ethylene glycol (EG), diethylene glycol (DEG), triethylene glycol (TEG), and tetraethylene glycol (T 4 EG). Normally a single type of pure glycol is used in a dehydrator, but sometimes a glycol blend is economically attractive.
