A process for the epoxidation of an olefin, which process comprises reacting a feed comprising the olefin, oxygen and a reaction modifier in the presence of a silver-based catalyst with the reaction modifier being present in a relative quantity Q which is the ratio of an effective molar quantity of active species of the reaction modifier present in the feed to an effective molar quantity of hydrocarbons present in the feed, and which process comprises the steps of:- operating at a first operating phase wherein the value of Q is Q1, and- subsequently operating at a second operating phase wherein the feed composition is different from the feed composition employed in the first operating phase, such that the value of Q is Q2, whereby the value of the quotient Q2/Q1 is in the range of from 0.5 to 1.5; a system suitable for performing the process; and a computer program product and a computer system suitable for use in connection with the process.

La présente invention concerne un procédé permettant l'époxydation d'une oléfine. Ce procédé implique de disposer d'un flux fournissant oléfine, oxygène et un modificateur de réaction, et de faire réagir ce flux en présence d'un catalyseur argentique. Le modificateur de réaction est présent en une proportion Q exprimant un rapport entre, d'une part la quantité molaire effective d'espèce actives du modificateur présent dans le flux, et d'autre part la quantité molaire effective d'hydrocarbures présents dans le flux. Ce procédé se décompose en deux temps. On lance d'abord une première phase où Q vaut Q¿1?. On passe ensuite à une seconde phase dans laquelle la composition du flux d'alimentation est différente de celle du flux de la première phase, Q valant maintenant Q¿2? tel que le rapport Q¿2?/Q¿1? reste dans une plage comprise entre 0,5 et 1,5. L'invention concerne également un système permettant la réalisation du procédé. L'invention concerne enfin un progiciel et un système informatique convenant à l'utilisation en relation avec le procédé.
