Abstract (en)
[origin: WO2022214214A1] The invention relates to a SPECTRA method for low-temperature fractionation of air, in which sump liquid from an additional second rectification column (12) used to obtain oxygen is evaporated in a second condenser-evaporator (121). In this second condenser-evaporator (121), gas that has been evaporated beforehand in a first condenser-evaporator (111), which is used for condensation of head gas from a first rectification column (11), is partially condensed after recompression. The invention also relates to a corresponding plant (100, 200, 300).
