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:
“Bankers, nepotists, contracts and talkies: on four fingers one may count the leeches which have sucked a young and vigorous industry into paresis.”
—Dalton Trumbo (1905–1976)
“The Founding Fathers in their wisdom decided that children were an unnatural strain on parents. So they provided jails called schools, equipped with tortures called an education. School is where you go between when your parents can’t take you and industry can’t take you.”
—John Updike (b. 1932)
