Title (EN) PRODUCTION OF SYNTHESIS GAS BLENDS FOR CONVERSION TO METHANOL OR FISCHER-TROPSCH LIQUIDS
(FR) FABRICATION DE MELANGES DE GAZ DE SYNTHESE DESTINES A LA CONVERSION EN METHANOL OU EN LIQUIDES FISCHER-TROPSCH
Abstract:
(EN) The present invention provides a process for producing synthesis gas blends which are especially suitable for conversion either into oxygenates such as methanol or into Fischer-Tropsch liquids. Such a process involves reforming of two separate gaseous hydrocarbon feedstreams (102, 111) (formed, for example, by dividing a natural gas feedstock) in a steam-reforming unit (10) and an oxygen-blown reforming unit (15) , respectively. The syngas effluent from each reforming unit is then combined, after appropriate pressure adjustments, to realize a synthesis gas blend (116) containing selected amounts and ratios of H2, CO and CO2. In further invention embodiments, processes are provided for converting the resulting syngas blends into oxygenates or Fischer-Tropsch hydrocarbons. Further conversion of the oxygenates so produced into light olefins also constitutes part of this invention.
(FR) La présente invention concerne un procédé de fabrication de mélanges de gaz de synthèse particulièrement adaptés à la conversion soit en oxygénates tels que le méthanol, soit en liquides Fischer-Tropsch. Un tel procédé comprend le reformage de deux courants d'alimentation d'hydrocarbures gazeux séparés (102, 111) (formés, par exemple, en divisant un produit de départ à base de gaz naturel) respectivement dans une unité de reformage à la vapeur (10) et dans une unité de reformage à oxygène pulsé (15). Les effluents de gaz de synthèse de chaque unité de reformage sont ensuite mélangés, après les réglages de pression appropriés, de manière à obtenir un mélange de gaz de synthèse (116) contenant les quantités et les rapports voulus en H2, CO, et CO2. D'autres modes de réalisation de la présente invention concernent des procédés de conversion des mélanges de gaz de synthèse résultants en oxygénates ou en hydrocarbures Fischer-Tropsch. Cette invention concerne également la conversion supplémentaire des oxygénates ainsi obtenus en oléfines légères.
