Abstract:
A method for producing a diesel having improved cold flow properties, the method comprising the steps of introducing a crude oil to a distillation column, separating the crude oil in the distillation unit to produce a light gas oil, and a light vacuum gas oil, where the light gas oil has a T95% cut point in the range between 300 deg C. and 340 deg C., where the light vacuum gas oil has a T95% cut point in the range between 400 deg C. and 430 deg C., processing the light vacuum gas oil in the supercritical water unit to produce an upgraded vacuum gas oil, separating the upgraded vacuum gas oil in the fractionator to produce an upgraded light fraction, an upgraded light gas oil, and upgraded heavy fraction, introducing the upgraded light gas oil into a diesel pool, and blending the light gas oil into the diesel pool.

Claim (Index 8):
The method of  claim 1 , where the step of processing the light vacuum gas oil in the supercritical water unit comprises the steps of:\n increasing the pressure of the light vacuum gas oil in a hydrocarbon pump to produce a pressurized hydrocarbon feed, where the pressure of the pressurized hydrocarbon feed is greater than the critical pressure of water; increasing the temperature of pressurized hydrocarbon feed in a hydrocarbon heater to produce a hot hydrocarbon stream, where the temperature of the hot hydrocarbon stream is between 10 deg C. and 300 deg C.; mixing the hot hydrocarbon stream with a supercritical water in a mixer to produce a mixed feed stream; introducing the mixed feed stream to a supercritical reactor, where the temperature in the supercritical reactor is in the range between 380 deg C. and 600 deg C. and the pressure in the supercritical reactor is in the range between 3203 psig and 5150 psig, where the residence time in the supercritical reactor is in the range between 10 seconds and 60 minutes; allowing conversion reactions in the supercritical reactor to produce an effluent stream such that the mixed feed stream undergoes conversion reactions; reducing the temperature of the effluent stream to a cooling device to produce a cooled stream, where the cooled stream is at a temperature in the range between 10 deg C. and 200 deg C; reducing the pressure of the cooled stream in a depressurizing device to produce a modified stream, where the pressure of modified stream is in the range between 0 psig and 300 psig; introducing the depressurizing device to a separator; separating the modified stream in the separator to produce a gases stream and a liquid stream; introducing the liquid stream to an oil-water separator; and separating the liquid stream in the oil-water separator to produce the upgraded vacuum gas oil and a water product.
