    Abstract: According to the present invention, a method for cryogenic separation of air using an air separation unit (100) comprising a rectification column (5) is provided. Feed air is compressed, cooled and rectified in the rectification column (5) obtaining an overhead gas, wherein a part of the overhead gas of the rectification column (5) is condensed using fluid withdrawn from the rectification column (5), wherein the condensed overhead gas is used at least in part as a liquid reflux to the rectification column (5), wherein a first part of the fluid which is used for cooling the overhead gas of the rectification column (5) is, after its use for cooling, compressed and reintroduced into the rectification column (5), and wherein a second part of the fluid which is used for cooling the overhead gas of the rectification column (5) is, after its use for cooling, expanded and withdrawn from the air separation unit (100). According to the present invention, for compressing the first part of the fluid which is used for cooling the overhead gas of the rectification column (5) a compressor (6) which is coupled to an electric motor (M) via a first gearbox (61) is used, for expanding the second part of the fluid which is used for cooling the overhead gas of the rectification column (5) an expansion turbine (7) which is coupled to an electric generator (G) via a second gearbox (71) is used, and the first gearbox (61) and the second gearbox (71) are identically designed. A corresponding air separation unit (100) is also part of the present invention.
