A cryogenic unit for the separation of gases includes at least one distillation column (1) is preassembled in the factory. The column (1) with added tubing elements (2) constitutes a pre-equipped subassembly which is transported and installed at the worksite. The tubing elements are disposed so as to be inscribed in at least one elongated volume (3; 3.sub.1, 3.sub.2) lateral to the column and of reduced section. The subassembly (1,2) is disposed on at least one transport cradle (4, 4') and transported to the worksite on the cradle and mounted at the worksite in a cold box (10) Preferably, all the tubing elements are disposed in the cradle. The subassembly, with or without the cradle, is mounted adjacent one side wall of the cold box (10) and is spaced by insulation (13) from at least one liquid gas reservoir (11; 12) also in the cold box (10).
In a process for the construction of a cryogenic unit for the separation of gases including at least one distillation column (1), comprising the steps of preassembling in a factory a said column (1) with added tubing elements (2) to constitute a pre-equipped subassembly, and transporting and installing the subassembly at a worksite;
