Abstract (en)
[origin: EP0306164A1] A temperature-sensitive hydrocarbonaceous waste stream (1) containing a non-distillable component is converted into a hydrogenated distillable hydrocarbonaceous product (16) and a heavy non-distillable product (4) while minimizing thermal degradation of the hydrocarbonaceous stream by (a) contacting the hydrocarbonaceous waste stream (1) with a hot first hydrogen-rich gaseous stream (10) in a flash zone (2) at flash conditions thereby increasing the temperature of the waste stream and vaporizing at least a portion thereof to provide a vapour stream (3) and a heavy product (4) comprising the non-distillable component; (b) catalytically hydrogenating the vapour stream in a hydrogenation reaction zone (5); and (c) condensing (8) at least a portion of the effluent (6) from the hydrogenation reaction zone (5) to provide a second hydrogen-rich gaseous stream (10) and a liquid stream comprising hydrogenated distillable hydrocarbonaceous products (16).
