Abstract: Methods of refining a whole crude oil stream. The methods involve first processing the crude either through a hydrotreating reactor comprising a dewaxing reactor bed or a flash evaporation separator. The treated streams are then further processed through a demetalization reactor bed, a hydroprocessing reactor bed, or both. The stream can then be still further processed via additional hydrotreating, distillation, or both.

Abstract: Hydroprocessed residual fuel and/or fuel blending components are provided that have a sulfur and nitrogen level comparable to liquefied natural gas (LNG). Because of the low starting level of sulfur and/or nitrogen, the severity of the hydroprocessing that is needed for the crude oil or bottoms fraction in order to remove sulfur to a level that is comparable to LNG is reduced or minimized. This can allow the resulting marine residual fuels to have low carbon intensity, low SOx and NOx emission and high energy density. Since the hydroprocessed fractions correspond to a fuel oil product, the resulting marine fuel can be used in existing fleets, and can be distributed in existing bunkering systems.

Abstract: Method of refining whole crude oil or a wide cut crude oil, the methods comprising a combination of a hydrotreating reactor, a distillation tower, and an optional flash evaporation separator. The methods can also include light ends processing, fluid catalytic cracking, reforming, hydrocracking, and demetalization. In some methods a whole crude oil is first processed through a flash evaporation separator to create a wide cut crude oil and in other methods, the flash evaporation separator is not used as the whole crude oil is first treated in a hydrotreater.

Abstract: Kerosene boiling range or jet fuel boiling range compositions are provided that are formed from crude oils with unexpected combinations of high naphthenes to aromatics weight and/or volume ratio and a low sulfur content. The resulting kerosene boiling range fractions can have an unexpected combination of a high naphthenes to aromatics weight ratio, a low but substantial aromatics content, and a low sulfur content. Such fractions can potentially be used as fuel after a reduced or minimized amount of additional refinery processing. By reducing, minimizing, or avoiding the amount of refinery processing needed to meet fuel and/or fuel blending product specifications, the fractions derived from the high naphthenes to aromatics ratio and low sulfur crudes can provide fuels and/or fuel blending products having a reduced or minimized carbon intensity.
