In Industry
Heat exchangers are widely used in industry both for cooling and heating large scale industrial processes. The type and size of heat exchanger used can be tailored to suit a process depending on the type of fluid, its phase, temperature, density, viscosity, pressures, chemical composition and various other thermodynamic properties.
In many industrial processes there is waste of energy or a heat stream that is being exhausted, heat exchangers can be used to recover this heat and put it to use by heating a different stream in the process. This practice saves a lot of money in industry, as the heat supplied to other streams from the heat exchangers would otherwise come from an external source that is more expensive and more harmful to the environment.
Heat exchangers are used in many industries, indluding:
- Waste water treatment
- Refrigeration
- Wine and beer making
- Petroleum refining
In waste water treatment, heat exchangers play a vital role in maintaining optimal temperatures within anaerobic digesters to promote the growth of microbes that remove pollutants. Common types of heat exchangers used in this application are the double pipe heat exchanger as well as the plate and frame heat exchanger.

Famous quotes containing the word industry:
“As our boys and men are all expecting to be Presidents, so our girls and women must all hold themselves in readiness to preside in the White House; and in no city in the world can honest industry be more at a discount than in this capital of the government of the people.”
—Jane Grey Swisshelm (1815–1884)
“Do not put off your work until tomorrow and the day after. For the sluggish worker does not fill his barn, nor the one who puts off his work; industry aids work, but the man who puts off work always wrestles with disaster.”
—Hesiod (c. 8th century B.C.)
