| description | The invention relates to a method for the cryogenic separation of air, in which an air separation plant (100-400) having a first rectification column (11) and a second rectification column (12) is used, in which cooled compressed air is supplied to the first rectification column (11) and a liquid from the first rectification column (11) or a liquid formed therefrom is supplied to the second rectification column (12). The overhead gas of the first rectification column (11) is condensed by means of a first condenser evaporator (111) and the liquid from the second rectification column (12) or the liquid formed therefrom is evaporated to obtain a first evaporation product. The overhead gas of the second rectification column (11) is condensed by means of a second condenser evaporator (121) and further liquid from the second rectification column (12) or liquid formed therefrom is evaporated to obtain a second evaporation product. A first portion of the second evaporation product is expanded, heated and discharged f |
