AIR PREPARATION METHOD AND DEVICE WITH A CARBON DIOXIDE ADSORPTION AND OXYGEN ENRICHMENT PROCESS

摘要

The invention relates to a method for generating prepared air. The method has the following steps: providing compressed air, reducing the carbon dioxide content of the compressed air in a carbon dioxide adsorption device (22), introducing the compressed air with an optionally reduced carbon dioxide content into a separating device (20), which contains a membrane (13) for separating nitrogen, conducting prepared air away from the separating device (20), conducting separated nitrogen away from the separating device (20), and at least partly regenerating the carbon dioxide adsorption device (22) using at least one part of the separated nitrogen.
