Zusammenfassung:An integrated apparatus for separating a mixture of carbon dioxide and at least one other gas and for separating air by air distillation is provided. The apparatus includes a CO2 separation unit configured to separate the mixture, an air separation unit configured to separate air by cryogenic distillation, a water cooling tower that operates by direct contact, a line for sending water to the top of the tower, a line for sending at least one portion of the nitrogen-enriched gas stream to a lower level of the tower, a cooled water line for withdrawing cooled water from the tower and means for cooling the air upstream of the air separation unit, the cooled water line being connected to means for cooling the air upstream of the air separation unit and to the inlet and/or to the outlet of the unit for separating the gaseous mixture.
