Cooling Towers
Cooling towers remove heat from a warm liquid by contacting it with a cool, dry gas. Some of the liquid vaporizes and enters the gas stream. The vaporization removes heat from the liquid stream. The outgoing streams are a humid gas containing the vaporized liquid feed component and a cooled liquid. This cooled liquid can be used for other cooling needs in a chemical process. Cooling towers are most commonly used for air-water systems.
