Title (EN) RAPID INJECTION PROCESS AND APPARATUS FOR PRODUCING SYNTHESIS GAS
(FR) PROCEDE ET APPAREIL D'INJECTION RAPIDE POUR LA PRODUCTION DE GAZ SYNTHETIQUE
Abstract:
(EN) A novel injector/reactor apparatus and an efficient process for the partial oxidation of light hydrocarbon gases, such as methane, to convert such gases to useful synthesis gas for recovery and/or subsequent hydrocarbon synthesis. Sources of a light hydrocarbon gas, such as methane (23), and oxygen or an oxygen-containing gas (22) are preheated and pressurized and injected through an injector means at high velocity into admixture with each other in the desired relating proportions, at a plurality of mixing nozzles which are open to the partial oxidation zone of a reactor and are uniformly-spaced over the face of the injector means, to form a gaseous premix having a pressure drop through the injector. The gasous premix is injected in a time period which is less than 5 milliseconds, preferably at a velocity between about 25 to 1000 feet/second, into a partial oxidation reaction zone so that the gaseous premix reacts therein, to reduce the amounts of CO2, H2O and heat produced by the partial oxidation reaction and form, cool and recover a useful syngas.
(FR) L'invention concerne un nouvel appareil à réacteur/injecteur et un procédé efficace pour l'oxydation partielle de gaz d'hydrocarbures légers, tel que le méthane, pour la conversion desdits gaz en gaz synthétique utile, pour la récupération et/ou la synthèse ultérieure d'hydrocarbures. Les sources de gaz d'hydrocarbures légers, tel que le méthane (23), et de l'oxygène ou un gaz contenant de l'oxygène (22) sont préchauffés, pressurisés et injectés par un moyen formant injecteur, à grande vitesse, sous forme de mélange, dans les proportions correspondantes voulues, au niveau de plusieurs buses de mélange qui donnent dans la zone d'oxydation partielle d'un réacteur et qui sont espacées régulièrement sur la face dudit moyen formant injecteur, de sorte qu'un prémélange gazeux à perte de pression soit formé dans l'injecteur. Le prémélange gazeux est injecté pendant moins de 5 millisecondes, de préférence à une vitesse comprise entre environ 25 à 1 000 pieds/seconde, dans une zone d'oxydation partielle de sorte que ledit prémélange réagisse à l'intérieur de celui-ci, et que la quantité de CO2, H2O et de chaleur produite par l'oxydation partielle soit réduite et qu'un gaz synthétique soit formé, refroidi et récupéré.
