Title (EN) COMPOSITION MADE FROM UREA FOR TREATING EXHAUST GASES
(FR) COMPOSITION A BASE D'UREE POUR LE TRAITEMENT DES GAZ D'ECHAPPEMENT
Abstract:
(EN) An aqueous composition comprising an NOx reducing agent or a precursor of such an agent, in particular urea, and at least one paraffin dispersed in the aqueous phase. Such a composition can be used for reducing the formation of deposits in an SCR exhaust system while preventing foaming during the handling of same.
(FR) Composition aqueuse comprenant un agent réducteur des NOx ou un précurseur d'un tel agent, notamment de l'urée, et au moins une paraffine dispersée dans la phase aqueuse. Une telle composition permet de réduire la formation de dépôts dans une ligne d'échappement SCR tout en évitant de mousser lors de sa manipulation.
