Abstract (en)
Process for hydrotreating a hydrocarbon oil employing several reactor vessels, which process comprises: (i) further hydrotreating partly hydrotreated hydrocarbon oil (8) of step (iv) in a first reactor vessel (1) in the presence of clean hydrogen containing gas (1), (ii) separating (3) the mixture obtained in step (i) within the first reactor vessel into a hydrotreated hydrocarbon oil (4) and used hydrogen containing gas (3), which hydrotreated hydrocarbon oil can be recovered as product, (iii) hydrotreating fresh hydrocarbon oil (5) in the second reactor (2) vessel in the presence of used hydrogen containing gas (3) obtained in step (ii), (iv) separating the effluent of step (iii) into partly hydrotreated hydrocarbon oil (8) and contaminated hydrogen containing gas (7), and (v) transporting partly hydrotreated hydrocarbon oil obtained in step (iv) to step (i).
