Abstract

A process for the production of low sulfur hydrocarbonaceous products. The hydrocarbon feedstocks are processed in integrated desulfurization zone (3), hydrocracking (21) and hydrogenation zones (22) to produce ultra low sulfur diesel (38), low sulfur naphtha products (37) and low sulfur heavy distillate (17).

Claims (7)

1. A process for desulfurizing two hydrocarbonaceous feedstocks which process comprises the following steps:
(a) reacting a first hydrocarbonaceous feedstock (1) comprising hydrocarbon components boiling above 343°F and hydrogen (28) with a desulfurization catalyst in a desulfurization zone (3) operated at desulfurization conditions to produce a desulfurization zone effluent (6);
(b) introducing the desulfurization zone effluent into a vapor-liquid separator (5) operated at a temperature greater than 288°C to provide a vaporous stream (17) comprising hydrogen, hydrogen sulfide and lower boiling hydrocarbonaceous compounds boiling up to 371°C and a first liquid hydrocarbonaceous stream (6) comprising hydrocarbon components boiling above 371°C and having a reduced concentration of sulfur;
(c) passing the vaporous stream (17) comprising hydrogen, hydrogen sulfide and lower boiling hydrocarbonaceous compounds boiling up to 371°C and a second hydrocarbonaceous feedstock (18) comprising hydrocarbon components boiling below 371°C to a hydrocracking zone (21) to produce a hydrocracking zone effluent;
(d) passing the hydrocracking zone effluent and a hydrocarbonaceous recycle stream (16) boiling in the range from 149°C to 371°C to a hydrogenation zone (22) to produce a hydrogenation zone effluent (23);
(e) fractionating the hydrogenation zone effluent (23) to produce an ultra low sulfur hydrocarbonaceous steam (38) boiling in the range from 149 C
to 371°C; and fractionating the first liquid hydrocarbonaceous steam (6) recovered in step (b) to produce a hydrocarbonaceous recycle stream (16) boiling in the range from 149°C to 371°C and a second liquid hydrocarbonaceous stream (17) comprising hydrocarbon components boiling above 371°C and having a reduced concentration of sulfur.
2. The process of claim 1 wherein the first hydrocarbonaceous (1) feedstock is selected from the group consisting essentially of atmospheric gas oil, vacuum gas oil, coker distillates, cracked gas oils and admixtures thereof.
3. The process of claims 1 or 2 wherein the operating conditions for the desulfurization zone (5) include a temperature from 204°C to 482°C, a pressure from 2.1 MPa to 17.3 MPa and a liquid hourly space velocity from 0.1 hr-1 to 10 hr-1.
4. The process of claims 1 or 2 or 3 wlierein the operating conditions for the hydrogenation zone (22) include a temperature from 204°C to 482°C, a pressure from about 2.1 MPa to 17.3 MPa and a liquid hourly space velocity from 0.1 hr-1 to 10 hr-1.
5. The process of airy of claims 1 to 4 wherein the ultra low sulfur hydrocarbonaceous stream (38) produced in step (e) contains less than 50 wppm sulfur.
6. The process of any of claims 1 to 5 wherein the ultra low sulfur hydrocarbonaceous stream (38) produced in step (e) contains less than 10 wppm sulfur.
7. The process of any of claims 1 to 6 wherein the second feedstock (18) is selected from the group consisting of light cycle oil, straight run middle distillate, kerosene and diesel boiling range hydrocarbons and coker distillate.
