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.

Abstract: An integrated upgrading process for upgrading a heavy oil, the process comprising the steps of introducing a heavy oil to a visbreaker unit; processing the heavy oil in the visbreaker unit to produce a visbreaker product stream; feeding the visbreaker product stream to a fractionator; separating the visbreaker product stream in the fractionator to produce a bottoms stream, a gas oil stream, a naphtha stream, and a gas product stream; feeding the bottoms stream to a supercritical water unit; and processing the bottoms stream in the supercritical water unit to produce an upgraded bottoms stream.

Abstract: Embodiments of the disclosure provide a visbreaking system and method for upgrading heavy hydrocarbons. A heavy hydrocarbon feed is introduced to a furnace to produce a soaker feed stream. The soaker feed stream is introduced to a soaker to produce a soaker effluent stream. The soaker effluent stream is introduced to a fractionator to produce a visbreaker distillate stream and a visbreaker residue stream. The visbreaker residue stream and a water feed are introduced to a supercritical water reactor operated at supercritical conditions of water to produce an effluent stream. The effluent stream is introduced to a flash column to produce a gas phase stream including water and a liquid phase stream including water. A portion of the liquid phase stream and the heavy hydrocarbon feed is combined. Optionally, a portion of the gas phase stream and the heavy hydrocarbon feed is combined. Optionally, a portion of the gas phase stream is introduced to the fractionator.
