Ethylene Glycol is a clear, sweet, slightly viscous liquid that boils at 198°C. Its most common use is as an automotive antifreeze and it serve as an excellent coolant in automotive radiators. It has a freezing point of 9 °F (−12.9 °C) and a boiling point of 387 °F (197.3 °C), which makes it an excellent antifreeze. Ethylene glycol is also used as an ingredient in hydraulic fluids, printing inks, and paint solvents.

Hydrazine Hydrate is commonly used has Oxygen Scavenger in Hp and LP Boiler. The measurement of dissolved oxygen in boiler plants plays a vital role if the plant is to run efficiently and to be cost effective, with minimum down time. Even small quantities of dissolved oxygen in boiler water are capable of causing severe pitting in boilers of all pressures, and will reduce the boiler life dramatically. In boilers where high chloride levels exist, the effect of oxygen corrosion is increased. Therefore, the need to reduce dissolved oxygen content to a very low level is even more important.
