F25J3/04145 - 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; Providing pressurised feed air or process streams within or from the air fractionation unit; Arrangements of compressors and /or their drivers Mechanically coupling of different compressors of the air fractionation process to the same driver(s)
