F25J3/04157 - 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 Afterstage cooling and so-called "pre-cooling" of the feed air upstream the air purification unit and main heat exchange line
