F25J3/04224 - CPC Classification

Classification description:

Processes or apparatus for separating the constituents of gaseous or liquefied gaseous mixtures involving the use of liquefaction or solidification by rectification, i.e. by continuous interchange of heat and material between a vapour stream and a liquid stream for air; Purification and (pre-)cooling of the feed air; recuperative heat-exchange with product streams; Cooling of the purified feed air by recuperative heat-exchange; Heat-exchange with product streams; Parallel arrangement of the main heat exchange line in cores having different functions, e.g. in low pressure and high pressure cores Cores associated with a liquefaction or refrigeration cycle
