Title (EN) METHOD FOR PROCESSING HYDROCARBON PYROLYSIS EFFLUENT
(FR) PROCÉDÉ DE TRAITEMENT D’UN EFFLUENT DE LA PYROLYSE D’HYDROCARBURES
Abstract:
(EN) A method is disclosed for treating the effluent from a hydrocarbon pyrolysis process unit to recover heat and remove tar therefrom. The method comprises passing the gaseous effluent to at least one primary heat exchanger, thereby cooling the gaseous effluent and generating high pressure steam. Thereafter, the gaseous effluent is passed through at least one secondary heat exchanger having a heat exchange surface maintained at a temperature such that part of the gaseous effluent condenses to form in situ a liquid coating on said surface, thereby further cooling the remainder of the gaseous effluent to a temperature at which tar, formed by the pyrolysis process, condenses. The condensed tar is then removed from the gaseous effluent in at least one knock-out drum.
(FR) La présente invention décrit un procédé de traitement de l’effluent d’une unité de traitement de pyrolyse d'hydrocarbures pour récupérer la chaleur et retirer le goudron de l’effluent. Le procédé comprend le passage de l’effluent gazeux dans au moins un échangeur de chaleur primaire, pour ainsi refroidir l'effluent gazeux et générer de la vapeur à haute pression. Par la suite, l’effluent gazeux est passé par au moins un échangeur de chaleur secondaire qui possède une surface d’échange de chaleur maintenue à une température telle qu'une partie de l'effluent gazeux se condense pour former in situ un revêtement liquide sur ladite surface, refroidissant ainsi davantage le reste de l'effluent gazeux à une température à laquelle le goudron, produit par le traitement de pyrolyse, se condense. Le goudron condensé est ensuite retiré de l’effluent gazeux dans au moins un séparateur.
