Ultra low sulfur marine fuel compositions

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.

Catalyst for heavy oil upgradation

A catalyst is provided having: (a) at least one multimetallic salt; and (b) at least one organic acid, wherein the at least one multimetallic salt to the at least one organic acid weight ratio is in the range of 1:0.01-1:0.5. A process is also provided for the preparation of the catalyst and for the preparation of the multimetallic salt.

APPARATUS AND PROCESS FOR UPGRADING HEAVY HYDROCARBONS

Systems and methods are provided for partial upgrading of heavy hydrocarbon feeds to meet transport specifications, such as pipeline transport specifications. The systems and methods can allow for one or more types of improvement in heavy hydrocarbon processing prior to transport. In some aspects, the systems and methods can produce a partially upgraded heavy hydrocarbon product that satisfies one or more transport specifications while incorporating an increased amount of vacuum gas oil and a reduced amount of pitch into the partially upgraded heavy hydrocarbon product. In other aspects, the systems and methods can allow for increased incorporation of hydrocarbons into the fraction upgraded for transport, thereby reducing or minimizing the amount of hydrocarbons requiring an alternative method of disposal or transport. In still other aspects, the systems and methods can allow for reduced incorporation of external streams into the final product for transport while still satisfying one or more target properties.

SYNTHETIC CRUDE COMPOSITION

An upgraded crude composition is provided, along with systems and methods for making such a composition. The upgraded crude composition can include an unexpectedly high percentage of vacuum gas oil boiling range components while having a reduce or minimized amount of components boiling above 593° C. (1100° F.). In some aspects, based in part on the hydroprocessing used to form the upgraded crude composition, the composition can include unexpectedly high contents of nitrogen. Still other unexpected features of the composition can include, but are not limited to, an unexpectedly high nitrogen content in the naphtha fraction; and an unexpected vacuum gas oil fraction including an unexpectedly high content of polynuclear aromatics, an unexpectedly high content of waxy, paraffinic compounds, and/or an unexpectedly high content of n-pentane asphaltenes.

For the shipping industry, these fuels provide solutions to long outstanding technical problems that heretofore hindered supply of low sulfur marine fuels in quantities needed to meet worldwide sulfur reduction goals. Marine shipping use of high sulfur bunker oils is reported as largest source of world-wide transportation SOx emissions. When ships on the open seas burn cheap low grade heavy bunker oils high in sulfur, nitrogen and metals, the SOx, NOx, and metal oxides go to the environment. This invention converts essentially all of each barrel of crude feed to a single ultraclean fuel versus conventional refining where crude feed is cut into many pieces, and each piece is sent down a separate market path meeting various different product specifications. When in port, ships can use these fuels to generate and sell electricity to land based electrical grids to offset fuel cost in an environment-friendly manner.

Tower bottoms coke catching device

A coke catching apparatus for use in hydrocarbon cracking to assist in the removal of coke and the prevention of coke build up in high coking hydrocarbon processing units. The apparatus includes a grid device for preventing large pieces of coke from entering the outlet of the process refining equipment while allowing small pieces of coke to pass through and be disposed of. The coke catching apparatus can be easily disassembled to be removed from the refining process equipment and cleaned.

Co-processing of biomass oil in coker

Systems and methods are provided for co-processing of biomass oil with mineral coker feeds in a coking environment. The coking can correspond to any convenient type of coking, such as delayed coking or fluidized coking. The biomass oil can correspond to biomass oil with a molar ratio of oxygen to carbon of 0.24 or less on a dry basis. Such types of biomass oil can be formed from pyrolysis methods such as hydrothermal pyrolysis, and are in contrast to biomass oils formed from pyrolysis methods such as fast pyrolysis. By using a biomass oil with a molar ratio of oxygen to carbon of 0.24 or less, improved yields of light coker gas oil can be achieved in conjunction with a reduction in the yield of heavy coker gas oil.

Integrated Desolidification for Solid-Containing Residues

A desolidification process enables the isolation and extraction of solid additives from an unreacted petroleum residue stream. In a hydrocracking process that mixes a solid additive with a petroleum residue feedstock to convert the petroleum residue to higher-value distillates, the desolidification process enables the recovery of the unreacted petroleum residue for conversion to a saleable product. The desolidification process involves the mixture of one or more solvents with a slurry in which solids are integrated in the petroleum residue to generate a mixture having a decreased density and viscosity as compared to the slurry, which facilitates removal of the solids.

HYDROPROCESSING OF HEAVY CRUDES BY CATALYSTS IN HOMOGENEOUS PHASE

This disclosure relates to a procedure, which through the application of a catalyst in homogeneous phase, allows the transformation of heavy hydrocarbons (vacuum residue, atmospheric residue, heavy and extra-heavy crudes) into hydrocarbons of lower molecular weight, characterized because after its application, the hydrocarbons obtain greater API gravity, lower kinematic viscosity and different composition by hydrocarbon families (SARA) that increases the proportion of saturated and aromatic resins and asphalts. The sulphur and nitrogen content is also reduced, resulting in higher yields to high commercial value distillates and a lighter product as compared to the original crude.
