Abstract[English]
A method for recovering tobacco alkaloids from an air stream from a tobacco processing facility includes generating a stream of air from the tobacco processing facility. The stream of air comprises the one or more tobacco alkaloids. The process includes humidifying the stream of air to generate a humidified air stream. The process further includes passing the humidified air stream across a first strong cation resin to sorb the one or more tobacco alkaloids and to generate a post-sorption air stream. The process further includes eluting the one or more tobacco alkaloids from the resin and collecting the eluted one or more tobacco alkaloids.[French]
Un procédé de récupération d'alcaloïdes de tabac à partir d'un flux d'air provenant d'une installation de traitement de tabac comprend la génération d'un flux d'air provenant de l'installation de traitement de tabac. Le flux d'air comprend le ou les alcaloïdes de tabac. Le procédé comprend l'humidification du flux d'air pour générer un flux d'air humidifié. Le procédé comprend en outre le passage du flux d'air humidifié à travers une première résine cationique forte en vue d'effectuer une sorption du ou des alcaloïdes de tabac et pour générer un flux d'air post-sorption. Le procédé comprend en outre l'élution du ou des alcaloïdes de tabac à partir de la résine et la collecte du ou des alcaloïdes de tabac élués.
