Process for treating a temperature-sensitive hydrocarbonaceous stream containing a non-distillable component

Patent ·
OSTI ID:6915823
This patent describes a process for treating a temperature- sensitive hydrocarbonaceous stream. It comprises: contacting the temperature-sensitive hydrocarbonaceous stream with a hot first hydrogen-rich gaseous stream having a temperature greater than the hydrocarbonaceous stream in a flash zone at flash conditions thereby increasing the temperature of the hydrocarbonaceous stream and vaporizing at least a portion thereof to provide a first hydrocarbonaceous vapor stream comprising hydrogen and a first heavy product stream comprising the non-distillable component; condensing at least a portion of the first hydrocarbonaceous vapor stream to provide a distillable heavy hydrocarbonaceous liquid stream and a second hydrocarbonaceous fraction; contacting the second hydrocarbonaceous vapor stream with a hydrogenation catalyst to increase the hydrogen content of the hydrogenatable hydrocarbonceous fraction introduced into the hydrogenation reaction zone; condensing at least a portion of the resulting effluent to provide a second hydrogen-rich gaseous stream and a liquid stream comprising hydrogenated distillable hydrocarbonaceous compounds; and recovering the selected hydrogenated distillable light hydrocarbonaceous product from the liquid stream.
