Title (EN) PROCESS AND APPARATUS FOR PRODUCING A FEED STREAM FOR A STEAM REFORMING PLANT
(FR) PROCÉDÉ ET APPAREIL DE PRODUCTION D'UN FLUX D'ALIMENTATION POUR UNE INSTALLATION DE REFORMAGE À LA VAPEUR
Abstract:
(EN) The invention relates to a process and an apparatus for producing an olefin-containing feed stream for a steam reforming plant. According to the invention, the olefin-containing hydrocarbon starting material is for this purpose vaporized and catalytically hydrogenated. The hydrogenation product stream obtained is separated into a gaseous reforming feed stream, which is fed to a steam reforming plant, and a gaseous recycle stream. As a result of the cooling according to the invention of the gaseous recycle stream down to at least partial condensation thereof and the separate recirculation of the gaseous partial recycle stream and of the liquid partial recycle stream, the procurement of a large and complicated circulation compressor is avoided and electric energy for operating this compressor is saved.
(FR) L'invention concerne un procédé et un appareil de production d'un flux d'alimentation contenant des oléfines pour une installation de reformage à la vapeur. Selon l'invention, le matériau de départ hydrocarboné contenant des oléfines est, à cet effet, vaporisé et hydrogéné catalytiquement. Le flux de produit d'hydrogénation obtenu est séparé en un flux d'alimentation de reformage gazeux, qui est alimenté dans une installation de reformage à la vapeur, et un flux de recyclage gazeux. Du fait du refroidissement selon l'invention du flux de recyclage gazeux jusqu'à au moins une condensation partielle de ce dernier et la recirculation séparée du flux de recyclage partiel gazeux et du flux de recyclage partiel liquide, l'acquisition d'un compresseur à circulation volumineux et compliqué est évitée et l'énergie électrique pour faire fonctionner ce compresseur est économisée.
