摘要：
The invention relates to a process for the low-temperature fractionation of air in a rectification unit, which comprises a pressure column (1) a low-pressure column (2) and a condenser-evaporator system having at least two falling-film evaporators (203, 204). Oxygen-rich liquid from the low-pressure column (2) is introduced into the evaporation passages of the first and second falling-film evaporators (203, 204) and is partially evaporated. Unevaporated oxygen-rich liquid from the first falling-film evaporator (203) is transferred into the evaporation passages of the second falling-film evaporator (204).
