F25J3/04521 - 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 Coupling of the air fractionation unit to an air gas-consuming unit, so-called integrated processes

Sub-classes:

F25J3/04527 » {Integration with an oxygen consuming unit, e.g. glass facility, waste incineration or oxygen based processes in general} 25
F25J3/04563 » {Integration with an nitrogen consuming unit, e.g. for purging, inerting, cooling or heating} 55
F25J3/04593 » {The air gas consuming unit is also fed by an air stream} 17
