Brazed aluminum heat exchangers are used in a number of applications, including cryogenic separation and liquefaction of air, natural gas processing and liquefaction, the production of petrochemicals and treatment of off-gases, and large refrigeration systems. The compact exchangers can handle tighter temperature approaches than other exchanger types, with benefits in energy recovery. In addition, their multi-stream capability provides increased flexibility in process flow-sheet design and in process integration.
