1. A cryogenic distillation unit, comprising:a distillation equipment including at least one cryogenic distillation column and at least one heat exchanger; and means for thermally insulating this equipment; said insulating means comprising a double-walled enclosure, said enclosure comprising an inner wall and an outer wall and, between said walls, a wall cavity which contains a solid insulator, the distillation equipment being arranged in a space defined by said inner wall, and a solid insulator supporting the inner wall of the enclosure and interposed between the floors of the two walls, said space being substantially free of any solid insulator; and legs which pass with a leaktight seal through the floor of the inner wall and bear on the floor of the outer wall and support the distillation column and the heat exchanger.
