  • Patent number: 9917320
    Abstract: A sweep membrane separator includes a membrane that is selectively permeable to a selected gas, the membrane including a retentate side and a permeate side. A mixed gas stream including the selected gas enters the sweep membrane separator and contacts the retentate side of the membrane. At least part of the selected gas separates from the mixed gas stream and passes through the membrane to the permeate side of the membrane. The mixed gas stream, minus the separated gas, exits the sweep membrane separator. A sweep gas at high pressure enters the sweep membrane separator and sweeps the selected gas from the permeate side of the membrane. A mixture of the sweep gas and the selected gas exits the sweep membrane separator at high pressure. The sweep membrane separator thereby separates the selected gas from the gas mixture and pressurizes the selected gas.

  • Patent number: 8926825
    Abstract: Methods for removing sulfur from hydrocarbon streams using the sequential application of hydrodesulfurization, fractionation and oxidation. The hydrodesulfurization step is operative to remove easily-hydrogenated sulfur species, such as sulfides, disulfides and mercaptans. The resultant stream is then fractionated at a select temperature range to generate a sub-stream that is sulfur-rich with the sulfur species resistant to removal by hydrodesulfurization. The sub-stream is then isolated and subjected to an oxidative process operative to oxidize the sulfur species to sulfones or sulfoxides, which may then be removed by a variety of conventional methods, such as absorption. Alternatively, the methods may comprise using the sequential application of fractionation to generate a sulfur-rich sub-stream followed by oxidation and subsequent removal of the sulfur species present in the sub-fraction. The latter methods are ideally suited for transmix applications.

  • Publication number: 20140251873
    Abstract: Reduction of sulfur-containing and nitrogen-containing compounds from hydrocarbon feeds is achieved by first contacting the entire feed with a hydrotreating catalyst in a hydrotreating reaction zone operating under mild conditions to convert the labile organosulfur and organonitrogen compounds. An extraction zone downstream of the hydrotreating reaction zone separates an aromatic-rich fraction that contains a substantial amount of the remaining refractory organosulfur and organonitrogen compounds. The aromatic-lean fraction is substantially free of organosulfur and organonitrogen compounds, since the non-aromatic organosulfur and organonitrogen compounds were the labile organosulfur and organonitrogen compounds which were initially removed by mild hydrotreating. The aromatic-rich fraction is oxidized to convert the refractory organosulfur and organonitrogen compounds to oxidized sulfur-containing and nitrogen-containing hydrocarbon compounds.

  • Publication number: 20130199968
    Abstract: Desulfurization of hydrocarbon feeds is achieved by first contacting the entire feed with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions; a flashing column downstream of the hydrodesulfurization reaction zone fractionates the effluent to obtain a first fraction which contains refractory organosulfur compounds and a second fraction that is substantially free of organosulfur compounds, since the organosulfur compounds boiling in the range of this fraction were the labile organosulfur compounds which were initially removed by mild hydrodesulfurization. The first fraction is contacted with a gaseous oxidizing agent over an oxidation catalyst having a formula CuxZn1-xAl2O4 in a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SOx and low sulfur hydrocarbons. The by-product SOx is subsequently removed, producing a stream containing a reduced level of organosulfur compounds.

  • Patent number: 8486258
    Abstract: A process for the hydrodesulfurization of gasoline is disclosed, the process including: feeding (1) a cracked naphtha containing mercaptans and other organic sulfur compounds and (2) hydrogen to a first hydrodesulfurization reactor containing one or more beds of a hydrodesulfurization catalyst; contacting sulfur compounds comprising the other organic sulfur compounds in the cracked naphtha with hydrogen in the presence of a hydrodesulfurization catalyst to convert a portion of the other organic sulfur compounds to hydrogen sulfide; withdrawing from the hydrodesulfurization reactor an effluent comprising hydrocarbons and hydrogen sulfide. The effluent from the hydrodesulfurization reactor is fed to a membrane separation system containing a membrane for partitioning the hydrocarbons from the hydrogen sulfide. For example, the membrane may be selective to hydrogen sulfide, to separate a permeate fraction comprising hydrogen sulfide from a residue fraction comprising the hydrocarbons.

    Abstract: Heavy oil feeds are hydroprocessed in the presence of a solvent under conditions that provide a variety of benefits. The solvent can be an added solvent or a portion of the liquid effluent from hydroprocessing. The processes allow for lower pressure processing of heavy oil feeds for extended processing times or extended catalyst lifetimes be reducing or mitigating the amount of coke formation on the hydroprocessing catalyst.

  • Patent number: 8409427
    Abstract: The present invention provides a method and apparatus for producing a treated hydrocarbon containing stream for use as a feed to a steam methane reformer of a hydrogen plant. In accordance with such method, amounts of olefins and organic sulfur species within an untreated feed are decreased in a reactor that is operated in either a hydrogenation mode to hydrogenate the olefins into saturated hydrocarbons or a pre-reforming mode in which hydrocarbon containing two or more carbon atoms including the olefins are reacted with oxygen and steam to form saturated hydrocarbons, methane, additional hydrogen and carbon monoxide. The reactor is configured and operates at a sufficiently high space velocity that olefin and organic species slip occurs that is further treated in a hydrotreater. The reactor contains a catalyst capable of promoting both hydrogenation and oxidation reactions and the hydrotreater contains a catalyst that is capable of only promoting hydrogenation reactions.

  • Patent number: 8318004
    Abstract: A method and apparatus for producing a treated hydrocarbon containing stream for use as a feed to a hydrogen plant having a steam methane reformer in which an untreated hydrocarbon containing stream is introduced into two reaction stages connected in series to hydrogenate olefins and to convert organic sulfur species to hydrogen sulfide. The second of the two stages can also be operated in a pre-reforming mode to generate additional hydrogen through introduction of the oxygen and steam into such stage. A sulfur tolerant catalyst is used in both stages to promote hydrogenation and oxidation reactions. Sulfur is removed between stages by adsorption of the hydrogen sulfide to prevent deactivation of the catalyst in the second of the stages that would otherwise occur during operation of the second reaction stage in a pre-reforming mode of operation.
