PROCESS FOR STABILIZATION OF REACTIVE LIQUID FEEDSTOCK

The present disclosure relates to a process and a process plant for conversion of a reactive liquid feedstock stream containing at least 40 wt% carbon, comprising the steps of a. directing a diluent stream, having a first combined hydrogen consumption potential and the reactive liquid feedstock stream as a combined stream having a first hydrogen consumption potential, to contact a material catalytically active in hydrotreatment which during operation has a lowest temperature of at least 80°C and a highest temperature of less than 250°C in the presence of dihydrogen, b. withdrawing a stabilized composition stream having a second combined hydrogen consumption potential which is less than 80% and more than 10% of the first hydrogen consumption potential, c. providing an amount of the liquid phase of said stabilized composition stream as said diluent stream wherein the hydrogen consumption potential for a composition shall be understood as the amount of hydrogen required for conversion of the composition into a saturated hydrocarbon. This has the associated benefit of the diluent being only partly converted and thus having a chemical nature favoring miscibility with the reactive feedstock, such that material catalytically active in hydrotreatment is contacted with a mixed liquid which is uniform, and which due to the dilution is less prone to polymerization and has a higher heat capacity, relative to the reactivity. La présente invention concerne un procédé et une installation de traitement pour la conversion d'un flux de charge de départ liquide réactive contenant au moins 40 % en poids de carbone, comprenant les étapes consistant à a. envoyer un flux de diluant, ayant un premier potentiel de consommation d'hydrogène combiné, et le flux de charge de départ liquide réactive sous forme d'un flux combiné ayant un premier potentiel de consommation d'hydrogène, pour qu'il vienne en contact avec un matériau catalytiquement actif en hydrotraitement qui, pendant le fonctionnement, a une température la plus basse d'au moins 80 °C et une température la plus élevée inférieure à 250 °C, en présence de dihydrogène, b. soutirer un flux de composition stabilisée ayant un second potentiel de consommation d'hydrogène combiné qui est inférieur à 80 % et supérieur à 10 % du premier potentiel de consommation d'hydrogène, c. utiliser une certaine quantité de la phase liquide dudit flux de composition stabilisée en tant que flux de diluant, le potentiel de consommation d'hydrogène
