Abstract (en)
[origin: DE19617377A1] An installation has at least one distillation column (7) in which a more volatile fraction (10), in particular nitrogen, is generated, as well as at least one source of refrigerated liquid. When starting the installation after an interruption, at least temporarily refrigerated liquid (22) is led from a given moment in time t0 from this source into a top area of the distillation column (7). No air (6) is introduced into the distillation column (7) between the starting moment t0 and a later moment in time t1 > t0.
