The present document relates to a process and system for continuous oxidation of a substance comprising one or more of a primary hydroxy group, an aldehyde group and/or a carbonyl group in which process carbon dioxide formed in the oxidation reaction is separated from nitrogen-containing off-gases of the reaction The nitrogen-containing off-gases are then recycled. Le présent document concerne un procédé et un système d'oxydation en continu d'une substance comprenant un ou plusieurs éléments parmi un groupe hydroxy primaire, un groupe aldéhyde et/ou un groupe carbonyle dans lequel le dioxyde de carbone de traitement formé dans la réaction d'oxydation est séparé des effluents gazeux contenant de l'azote de la réaction, les effluents gazeux contenant de l'azote étant ensuite recyclés.
