It is completely miscible with water and many organic liquids. As a consequence the head loss (pressure loss) in the a piping system with ethylene glycol is increased compared to clean water.

TCCs Ethylene Glycol (MEG) is a toxic, colorless, practically odorless, low-volatility, low-viscosity, hygroscopic liquid.

In a 50% solution with operational temperatures above 36 oF the specific heat capacity is decreased with approximately 20%.

Ethylene glycol is highly poisonous; animals or humans that drink the solution become very ill and may die.

Ethylene glycol is also commonly used in heating applications that temporarily may not be operated (cold) in surroundings with freezing conditions - such as cars and machines with water cooled engines.

Its most common use is as an automotive antifreeze. Its most common use is as an automotive antifreeze. The specific gravity of ethylene glycol based water solutions are increased compared with specific gravity of clean water. For a heat transfer system with ethylene glycol the circulated volume must be increased compared to a system only with water. Corrections?

0000003362 00000 n Distilled or deionized water should be used for ethylene glycol solutions. Ethylene Glycol based water solutions are common in heat-transfer applications where the temperature in the heat transfer fluid can be below 32oF (0oC). The end uses for ethylene glycol are numerous (See Table 1). trailer <]/Prev 1199023/XRefStm 2466>> startxref 0 %%EOF 1833 0 obj <>stream Please read Google Privacy & Terms for more information about how you can control adserving and the information collected. 0000022157 00000 n AddThis use cookies for handling links to social media.

Finally, ethylene glycol, which is widely used as an antifreeze agent in automobiles, causes renal damage when it is biotransformed to oxalic acid, which crystallizes in the renal tubule (Table 2).…, …freezing temperature decreases appreciably when ethylene glycol is mixed with water.…. From the table above we see that the density of the solution at installation temperature can be as high as 1090 kg/m3 - and the medium density at operation temperature can be as low as 1042 kg/m3. The specific heat of ethylene glycol based water solutions are less than the specific heat of clean water. Updates?
