Process for the simultaneous hydrogenation of a first feedstock comprising hydrocarbonaceous compounds and having a non-distillable component and a second feedstock comprising halogenated organic compounds

A process for the simultaneous hydrogenation of a first feedstock comprising hydrocarbonaceous compounds and having a non-distillable component, and a second feedstock comprising halogenated organic compounds which process comprises:

• (a) contacting said first feedstock with a first hydrogen-rich gaseous stream having a temperature greater than said first feedstock in a flash zone at flash conditions thereby increasing the temperature of said first feedstock and vaporizing at least a portion thereof to provide a hydrocarbonaceous vapor stream comprising hydrogen, and a heavy product comprising said non-distillable component;
• (b) contacting said hydrocarbonaceous vapor stream comprising hydrogen with a hydrogenation catalyst in a first hydrogenation reaction zone at hydrogenation conditions to increase the hydrogen content of said hydrocarbonaceous compounds contained in said hydrocarbonaceous vapor stream;
• (c) condensing at least a portion of the resulting effluent from said first hydrogenation reaction zone to produce a second hydrogen-rich gaseous stream and a first liquid hydrogenated stream comprising hydrogenated distillable hydrocarbonaceous compounds;
• (d) reacting said second feedstock comprising halogenated organic compounds and at least a portion of said second hydrogen-rich gaseous stream with a hydrogenation catalyst in a second hydrogenation reaction zone at hydrogenation conditions selected to produce hydrocarbonaceous compounds and at least one water-soluble inorganic halide compound;
• (e) contacting the resulting effluent from said second hydrogenation zone containing hydrocarbonaceous compounds and at least one water-soluble inorganic halide compound with a halide-lean aqueous scrubbing solution;
• (f) introducing a resulting admixture of said effluent from said second hydrogenation zone and said halide-lean aqueous scrubbing solution into a separation zone to provide a third hydrogen-rich gaseous stream, a second liquid hydrogenated stream comprising hydrocarbonaceous compounds and a halide-rich aqueous scrubbing solution containing at least a portion of said water-soluble inorganic halide compound;
• (g) recycling and heating at least a portion of said third hydrogen-rich gaseous stream recovered in step (f) into step (a) as at least a portion of said first hydrogen-rich gaseous stream;
• and
• (h) recovering said first liquid hydrogenated stream comprising hydrogenated distillable hydrocarbonaceous compounds from step (c) and said second liquid hydrogenated stream comprising hydrocarbonaceous compounds from step (f).
