  • Patent number: 11661556
    Abstract: The present invention relates to a sequential thermo-chemical treatment along with adsorption-based pre-treatment process for residual oils having a very high naphthenic acid content. First stage of the process is a thermal pre-treatment step which results into generation of hydrocarbon stream with a reduced naphthenic acid content due to high temperature. In second stage of pre-treatment, generated hydrocarbon stream from stage-1 is subjected to esterification reaction with alcohol, such as methanol, to further reduce the TAN of hydrocarbon stream. After recovery of alcohol from the reaction mixture, depending on TAN reduction required reaction mixture may be subjected to an adsorption stage, third stage pre-treatment, where an adsorbent mixture comprising of FCC spent catalyst is used to adsorb the TAN of feed hydrocarbon stream. The treated hydrocarbon stream is then co-processed with DCU feed stock for producing lighter hydrocarbons.

  • Patent number: 10954447
    Abstract: The invention relates to processes for producing anode grade coke from whole crude oil. The invention is accomplished by first deasphalting a feedstock, followed by processing resulting DAO and asphalt fractions. The DAO fraction is hydrotreated or hydrocracked, resulting in removal of sulfur and hydrocarbons, which boil at temperatures over 370° C., and gasifying the asphalt portion in one embodiment. This embodiment includes subjecting hydrotreated and/or unconverted DAO fractions to delayed coking. In an alternate embodiment, rather than gasifying the asphalt portion, it is subjected to delayed coking in a separate reaction chamber. Any coke produced via delayed coking can be gasified.

  • Patent number: 10808176
    Abstract: The delayed coking method includes directing a heated secondary feedstock, which contains heated primary feedstock and recirculate, from a reaction furnace to a coking chamber. Vapor-liquid coking products formed in the coking chamber are then directed to a fractionation column, which fractionates hydrocarbon gas, gasoline, light and heavy gas oils, and bottom residues. Heavy gas oil from the fractionation column is directed to a thermal cracking furnace, the products of which are cooled by cooled light gas oil and directed to an evaporator for separation. In the evaporator, gases and light boiling products are removed by evaporation and returned to the fractionation column, and the remaining distillate cracking residue is separated and used as a component of the recirculate, along with bottom residues from the fractionation column. The resulting process produces high quality and high yield needle and anode cokes.

  • Patent number: 10494577
    Abstract: Systems and methods are provided for upgrading aromatic refinery fractions by performing trim alkali metal desulfurization. The alkali metal desulfurization can be performed by mixing the aromatic refinery fraction with alkali metal in finely dispersed solid and/or molten form, such as molten sodium. The aromatic nature of the refinery fraction can potentially be beneficial for the desulfurization reaction mechanism. The aromatic refinery fractions can correspond to fractions that have been previously processed to remove metals. Because only trim desulfurization is being performed, the desulfurization can be performed under relatively mild alkali metal desulfurization conditions that result in a reduced or minimized amount of feed conversion.

  • Patent number: 8968553
    Abstract: Undesirable components of traditional coking processes are selectively cracked or coked in the coking vessel by injecting an additive into the vapors in the coking vessel. The additive contains catalyst(s), seeding agent(s), excess reactant(s), quenching agent(s), carrier(s), or any combination thereof to modify reaction kinetics to preferentially crack (or coke) these undesirable components that typically have a high propensity to coke, and are often precursors to coke in the coking process. These undesirable components can also be very problematic in downstream catalytic cracking processes, significantly contributing to coke on catalyst and catalyst deactivation. Exemplary embodiments of the present invention also provide methods to (1) decrease coke production, (2) increase liquid transportation fuels, (3) control the coke crystalline structure, and (4) control the quantity and quality of volatile combustible materials (VCMs) in the resulting coke.

  • Patent number: 8673131
    Abstract: The present invention relates to a method of preparing synthetic crude oil from a heavy crude reservoir, comprising: (a) extracting the heavy crude oil using a steam technology; (b) separating the crude extracted and the water; (c) separating the crude into at least one light cut and one heavy cut; (d) converting said heavy cut to a lighter product and a residue; (e) optionally, partially or totally hydroprocessing the converted product and/or the light cut(s) obtained upon separation (c); (f) burning and/or gasifying the conversion residue in the presence of metal oxides in at least one chemical looping cycle producing CO2-concentrated fumes in order to allow CO2 capture, the optionally hydroprocessed converted product and light separation cut(s) making up the synthetic crude oil, said combustion allowing to generate steam and/or electricity, and said gasification allowing to generate hydrogen, the steam and/or the electricity thus generated being used for extraction (a), and/or the electricity and/or the hy

  • Publication number: 20140061097
    Abstract: Undesirable components of traditional coking processes are selectively cracked or coked in the coking vessel by injecting an additive into the vapors in the coking vessel. The additive contains catalyst(s), seeding agent(s), excess reactant(s), quenching agent(s), carrier(s), or any combination thereof to modify reaction kinetics to preferentially crack (or coke) these undesirable components that typically have a high propensity to coke, and are often precursors to coke in the coking process. These undesirable components can also be very problematic in downstream catalytic cracking processes, significantly contributing to coke on catalyst and catalyst deactivation. Exemplary embodiments of the present invention also provide methods to (1) decrease coke production, (2) increase liquid transportation fuels, (3) control the coke crystalline structure, and (4) control the quantity and quality of volatile combustible materials (VCMs) in the resulting coke.

  • Patent number: 8658025
    Abstract: Biomass is used as a co-feed for a heavy petroleum oil coking process to improve the operation of the coking process and to utilize biomaterial for the production of transportation fuels. The coking process may be a delayed coking process or a fluidized bed coking process and in each case, the presence of the biomass will decrease the coke drying time so reducing coke handling problems in the unit besides forming a superior coke product. In the case of a fluidized bed coking process using a gasifier for the coke, the addition of an alkali metal salt improves the operation of the gasifier.

  • Patent number: 8568584
    Abstract: A method is described for controlling instability of operation in a de-ethanizer tower (13) in the gas recovery unit in fluid catalytic cracking units and delayed coking units. The method comprises the step of intervening in the de-ethanizer tower (13) when instability occurs in it, and adjusting the material balance of water in such a way that the excess of water in the feed load stream (9) is removed only as an azeotrope. The intervention is performed by introducing into the feed load stream (9) of the de-ethanizer tower (13) a volume fraction (18) of a flow of hydrocarbon, which may be either dry hydrocarbons or hydrocarbons with a low level of water content.
