In a method for producing a first pressurized gas and a second gas on a one-off basis by cryogenic distillation of air, according to a first step, no fluid heats up or cools down in a second heat exchanger, and according to a second step, a flow of pressurized liquid from the double column heats up and vaporizes in the second exchanger to form a gas required on a one-off basis, a flow of air at the second pressure cools in the second exchanger. |
