Title
(EN) DEVICE AND METHOD FOR CRACKING HYDROCARBONS AND METHOD FOR CLEANING SUCH A DEVICE
(FR) DISPOSITIF ET PROCEDE POUR LE CRAQUAGE D'HYDROCARBURES ET PROCEDE DE NETTOYAGE D'UN TEL DISPOSITIF
Abstract
(EN)
The invention relates to a device for cracking hydrocarbons, which device contains at least a convection section and a cracking section, and the convection section of which consists of one or more feed heaters which are connected in series and comprise one or more pipes connected in parallel, in which at least part of the pipes of the final feed heater is situated outside the casing of the device and the pipes contain means there via which at least part of the interior of the pipes is accessible. The invention also relates to a method for cleaning such a device, and to a method for cracking hydrocarbons, in which high-boiling fractions may or may not be present, in a device of this kind.
(FR)
Cette invention se rapporte à un dispositif pour le craquage d'hydrocarbures, qui comprend au moins une section de convection et une section de craquage. La section de convection de ce dispositif est constituée par un ou plusieurs éléments chauffants d'alimentation, lesquels sont reliés en série et comportent un ou plusieurs tuyaux reliés en parallèle. Au moins une partie des tuyaux de l'élément chauffant d'alimentation final est située à l'extérieur du logement du dispositif et les tuyaux contiennent des moyens grâce auxquels au moins une partie de l'intérieur des tuyaux est accessible. Cette invention se rapporte également à un procédé pour nettoyer un tel dispositif, ainsi qu'à un procédé pour effectuer dans un dispositif de ce type le craquage d'hydrocarbures, dans lesquels des fractions à point d'ébullition élevé peuvent être présentes ou peuvent ne pas être présentes.
