F25J3/04866 - 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; Start-up or control of the process; Details of the apparatus used Construction and layout of air fractionation equipments, e.g. valves, machines
