Abstract

L'invention concerne un procédé permettant de séparer du pétrole d'une substance contenant ce dernier. Ce procédé est mis en oeuvre dans des conditions comprenant la génération d'une onde de choc de Mach 1-2 dans un flux de vapeur surchauffée, et comprend les étapes consistant à introduire une substance contenant du pétrole dans ce flux de vapeur afin provoquer le craquage de cette substance contenant du pétrole sous l'effet de la chaleur produite par la vapeur surchauffée et de l'onde de choc, puis à séparer les composants vaporisés contenant du pétrole des composants résiduels. L'invention concerne également un séparateur d'hydrocarbures comprenant une buse qui permet de générer un flux de vapeur surchauffée, et une ouverture placée à l'intérieur du flux et servant à introduire les substances contenant du pétrole directement dans le flux. Du fait de la transmission efficace de la vapeur surchauffée et de l'onde de choc à la substance contenant du pétrole lorsque cette dernière est exposée à un flux de Mach 1-2, la substance contenant le pétrole est atomisée, ce qui augmente sa surface spécifique et accélère ainsi la vaporisation des composants de pétrole.
