An antifreeze is defined as an additive that, when added to a water-based fluid, will reduce the freezing point of the mixture (Stefl and George, 1996). Antifreezes are used in mechanical equipment that is environments below the freezing point of water to prevent the freezing of heat transfer fluids. They are also used in cementing jobs.
Hydrate control is not included in this chapter, but is discussed in Chapter 13, because of the relative importance and difference in chemical mechanism of these compounds. Many chemicals will result in a depression of the freezing point when added to water. Their practical application is restricted, however, because of some other unwanted effects, such as corrosion, destruction of ...
