Abstract

L'invention concerne un procédé de décokage de tubes réchauffeurs. Ce procédé utilise un courant turbulent de gaz, par exemple d'azote, entraînant des particules résistant aux chocs, par exemple de la grenaille d'acier. Il permet d'éliminer par voie mécanique le coke déposé à l'intérieur du tube sans détériorer la paroi de ces tubes. Domaine d'application : nettoyage de tubes réchauffeurs pour fours à hydrocarbures.
