Summary

Since a refrigeration system can cool down a process stream far below the ambient temperature, it is indispensable to cryogenic cooling and separation operations in many chemical industries, such as the large-scale production of ethylene, oxygen, nitrogen and liquefied natural gas (LNG). From a thermodynamic viewpoint, a mixed-refrigerant system provides refrigeration over a range of temperatures, with smaller temperature differences at the lower temperatures. This leads to a smaller increase in entropy, or a smaller loss of energy.
