Described is a method of improving the process and operation of an existing system for manufacturing ethylene oxide. The ethylene oxide manufacturing system includes an epoxidation reactor system containing a volume of high activity epoxidation catalyst. The method includes replacing a portion of the volume of high activity epoxidation catalyst with a volume of high selectivity catalyst, and modifying the operation of the process system so as to provide for a feed to the epoxidation reactor system having a reduced carbon dioxide concentration.
L'invention concerne un procédé d'amélioration de processus et de conduite de système existant pour la fabrication d'oxyde d'éthylène. Le système comprend un système de réaction d'époxydation qui contient un volume de catalyseur d'époxydation haute activité. Le procédé comprend les étapes suivantes : remplacement d'une partie du volume de ce catalyseur par un volume de catalyseur très sélectif, et modification de la conduite du système pour fournir au système de réaction une charge à concentration réduite en dioxyde de carbone.
