Title (EN) A PROCESS FOR OXIDATIVE COUPLING OF METHANE (OCM) AND A PROCESS SYSTEM FOR SUCH A PROCESS
(FR) PROCÉDÉ DE COUPLAGE OXYDANT DU MÉTHANE (OCM) ET SYSTÈME DE TRAITEMENT POUR UN TEL PROCÉDÉ
Abstract:
(EN) The present invention relates to a process for oxidative coupling of methane (OCM, 100) comprising the steps of feeding methane (104) and at least one oxidizing agent (103), preferably oxygen, into at least one OCM reactor (101) comprising at least one OCM catalyst, wherein C2+ alkene is generated from methane by the OCM catalyst; wherein at least part of the methane (104) is provided by at least one methanation unit (111), in which hydrogen and carbon dioxide are reacted to methane, wherein at least part of the hydrogen fed to the methanation unit (111) is provided from a hydrogen stream (211) generated in a propane dehydrogenation process (200), and/or wherein ethane (105) is fed into the at least one OCM reactor (101) comprising further at least one cracking unit, wherein C2+ alkene is generated from ethane in the cracking unit, wherein at least part of the ethane (105) is provided from ethane (213) generated in a propane dehydrogenation process (200). The invention also relates to a process system for such a process.
(FR) La présente invention concerne un procédé de couplage oxydant du méthane (OCM, 100) comprenant les étapes consistant à introduire du méthane (104) et au moins un agent oxydant (103), de préférence l'oxygène, dans au moins un réacteur OCM (101) comprenant au moins un catalyseur OCM, l'alcène en C2+ étant généré à partir de méthane par le catalyseur OCM ; au moins une partie du méthane (104) étant fournie par au moins une unité de méthanation (111), dans laquelle de l'hydrogène et du dioxyde de carbone réagissent au méthane, au moins une partie de l'hydrogène introduit dans l'unité de méthanation (111) étant fournie à partir d'un flux d'hydrogène (211) généré dans un processus (200) de déshydrogénation de propane, et/ou l'éthane (105) étant introduit dans le ou les réacteurs OCM (101) comprenant en outre au moins une unité de craquage, l'alcène en C2+ étant généré à partir de l'éthane dans l'unité de craquage, au moins une partie de l'éthane (105) étant fournie à partir de l'éthane (213) généré dans un processus (200) de déshydrogénation de propane. L'invention concerne également un système de traitement pour un tel procédé.
