Abstract
An integrated process for the production of a hydrogenated distillable hydrocarbonaceous product from a temperature-sensitive hydrocarbonaceous stream containing a non-distillable component by the utilization of a hot hydrogen flash zone and a secondary separation zone to achieve a high yield of hydrogenated distillable hydrocarbonaceous product.

A process for treating a temperature-sensitive hydrocarbonaceous stream containing a non-distillable component to produce a hydrogenated distillable hydrocarbonaceous product and a heavy product comprising said non-distillable component while minimizing thermal degradation of said hydrocarbonaceous stream which process comprises the steps of:
- (a) contacting said hydrocarbonaceous stream with a first hydrogen-rich gaseous stream having a temperature greater than said hydrocarbonaceous stream in a flash zone at flash conditions thereby increasing the temperature of said hydrocarbonaceous stream with minimal thermal degradation and vaporizing at least a portion thereof to produce a hydrocarbonaceous vapor stream comprising hydrogen and a heavy stream comprising said non-distillable component and entrained distillable hydrocarbonaceous compounds;
- (b) contacting said hydrocarbonaceous vapor stream comprising hydrogen recovered from step (a) without intermediate separation with a hydrogenation catalyst in a hydrogenation reaction zone at hydrogenation conditions to increase the hydrogen content of the hydrocarbonaceous compounds contained in said hydrocarbonaceous vapor stream;
- (c) condensing at least a portion of the resulting effluent from said hydrogenation reaction zone to produce a second hydrogen-rich gaseous stream and a liquid stream comprising hydrogenated distillable hydrocarbonaceous compounds;
- (d) separating said heavy stream comprising said non-distillable component and entrained distillable hydrocarbonaceous compounds in a separation zone to produce a heavy product stream comprising said non-distillable component and a stream comprising at least a portion of said entrained distillable hydrocarbonaceous compounds;
- (e) recycling at least a portion of said entrained distillable hydrocarbonaceous compounds to said hydrogenation reaction zone;
- and
- (f) recovering said liquid stream comprising hydrogenated distillable hydrocarbonaceous compounds produced in step (c).
