A method of cryogenic fractionation of air in an air fractionation plant (100, 200, 300), wherein the air fractionation plant (100, 200, 300) has a pressure column (11), a low-pressure column (12) and a first and second condenser-evaporator (11a,12b), wherein tops gas from the pressure column (11) is condensed in the first condenser-evaporator (11a), and tops gas from the low-pressure column (12) in the second condenser-evaporator (12a), wherein a first liquid is partly evaporated in the first condenser-evaporator (11a) to obtain a first residual liquid and a first evaporation gas, and second liquid which is collected in the pressure column (11), discharged from the pressure column (11) and expanded is partly evaporated to obtain a second residual liquid and a second evaporation gas, wherein the first residual liquid is evaporated in the second condenser-evaporator (12a), subjected to expansion in an expansion turbine (4b) coupled to a cold booster (4a) and discharged from the air fractionation plant (100, 200, 300), and wherein the second evaporation gas is subjected to compression in the cold booster (4a) and fed back into the pressure column (11). In the first condenser-evaporator (11a), the first and second evaporation passages both take the form of forced-flow evaporators. The cold booster is disposed on a common shaft with the expansion turbine (4b) and a dissipative brake.
