- There formed gas is warmed up as residual gas 30 in the UKG 18.
- the residual gas 31 downstream of the UKGs 18 is supplied to the main heat exchanger 8 at the cold end and heated there to an intermediate temperature.
- the residual gas 32 under the intermediate temperature is supplied to a first residual gas turbine 33 and there relaxes work.

- the residual gas turbine 33 does not deliver its entire mechanical energy to the cold compressor 36, but also drives a generator 40, which sits on the same shaft or is connected to the same gear.
- a dissipative brake may also be used, for example an oil brake.
- two parallel-connected residual gas turbines 33, 233 are used, one of which is coupled to the cold compressor 36 and the other to a generator 240 (or a dissipative brake).

- Nitrogen flow 37 from the head of the low-pressure column is compressed in the cold compressor 36 here accordingly only to 11, 1 bar, so not quite on the

- FIG. 7 differs from FIG. 6 in that, as the main condenser 12 and the low-pressure column top condenser 13, no bath evaporators but forced-flow evaporators are used. In this case, a purge stream 701 (purge) is withdrawn from the sump of the high-pressure column 10. As the main capacitor 12 may alternatively be used a falling film evaporator.
- high-pressure column 10 and low-pressure column 11 are not arranged one above the other as in FIGS. 1 to 7, but arranged next to one another. Otherwise, Figure 8 does not differ from Figure 4 or Figure 5 - depending on whether that
- Nitrogen product is discharged under high-pressure column pressure or under slightly lower pressure (throttle valve 619).
