The invention relates to an apparatus for the distillation separation of a mixture containing, as the main components thereof, carbon dioxide and at least one other fluid selected from the group containing nitrogen, oxygen, argon, hydrogen, methane, carbon monoxide, said apparatus comprising a distillation column (), a condenser (), a reboiler (), means for conveying the mixture to be separated to the column or the condenser, means for conveying a head gas from the column to the condenser, and means for conveying a liquid condensed in the condenser into the head of the column. The condenser is formed by an exchanger with plates and blades made from brazed aluminum and having an exchange surface area per mof exchanger greater than 400 m/m, with ammonia being used as refrigerant.
