  • Patent number: 10670568
    Abstract: Described are a method and a system for injecting a sample into a flow of a liquid chromatography system. The method includes combining a flow of a sample and a flow of a mobile phase to create a diluted sample in the system flow. The volumetric flow rate of the sample is controlled to be at a value that yields a desired dilution ratio for the diluted sample. The particular value at which the volumetric flow rate is maintained can be determined from the desired value of the dilution ratio and the volumetric flow rate of the mobile phase. System embodiments include a syringe that can be used to provide a sample solution at a controllable volumetric flow rate for combination with a high pressure mobile phase.

  • Patent number: 10533404
    Abstract: The invention relates to injecting steam into crude oil for several benefits, primarily of which is to remove salt by transferring the salt into the condensed water from the steam. Steam transfers salt via a different transfer mechanism and therefore doesn't require the high shear mixing of conventional water injection systems. As such, steam injection through a variety of procedures, is more efficient at gathering salt into water that itself is easier to remove from the crude oil.

    Abstract: A system and method for cleaning sulfur and other pollutants from bunker oil to be used for fuel in large cargo ships is described. Preferably, the system includes two or more stages having a mixer to create an emulsion of oil and water. One or more treatment chemicals are added to the water before it is mixed with the oil in order to assist in separating the sulfur from the oil and freeing it up so that it can combine with various other molecules present in the water or be dissolved in the water. The emulsion may pass through a microcavitation chamber as well as an electrolysis reactor chamber in order to further clean the fuel oil by removing additional sulfur content. The clean fuel is sent to a fuel service tank for use in a diesel engine combustion cycle.

    Abstract: One exemplary embodiment can be a process for removing one or more disulfide compounds from a caustic stream. The process can include passing the caustic stream, previously contacted with a hydrocarbon stream for removing one or more mercaptans, through a column to remove the one or more disulfide compounds downstream of a mercaptan oxidation zone.

  • Publication number: 20130313161
    Abstract: A process of hydroprocessing a hydrocarbon in a down flow reactor comprising one or more hydroprocessing-catalyst beds. The hydrocarbon feed is mixed with hydrogen and optionally diluent to form a liquid feed mixture wherein hydrogen is dissolved in the mixture, and the liquid feed mixture is introduced into the down flow reactor under hydroprocessing conditions. The hydroprocessing-catalyst bed(s) are liquid-full and the feed reacts by contact with the catalyst. Hydrogen gas is injected into at least one of the hydroprocessing-catalyst beds such that at least part of the hydrogen consumed in that bed is replenished and the liquid-full condition is maintained. In a multi-bed reactor, hydrogen gas may be injected into more than one or all of the hydroprocessing-catalyst beds.

  • Patent number: 8574429
    Abstract: A one-step process for desulfurizing an oxidized sulfone-containing fuel stream, such as a diesel stream, is disclosed where mass transfer and conversion of sulfone occurs simultaneously such that the sulfur atom in sulfone molecule is removed as sulfite to provide a low-sulfur diesel stream. The diesel stream for treatment is obtained as a result of the oxidation of a thiophene-rich diesel stream with an oxidant to provide a sulfone-containing diesel stream. The one-step process uses a single vessel having a shroud of vertical hanging fibers to affect the mass transfer of sulfones in diesel into contacting with an aqueous solution of alkali metal hydroxide where it is converted to sulfite and biphenyls. The sulfite-rich aqueous solution and low sulfur diesel are then separately removed from the vessel.

  • Patent number: 8535518
    Abstract: A petroleum feedstock upgrading method is provided. The method includes supplying a mixed stream that includes hydrocarbon feedstock and water to a hydrothermal reactor where the mixed stream is maintained at a temperature and pressure greater than the critical temperatures and pressure of water in the absence of catalyst for a residence time sufficient to convert the mixed stream into a modified stream having an increased concentration of lighter hydrocarbons and/or concentration of sulfur containing compounds. The modified stream is then supplied to an adsorptive reaction stage charged with a solid adsorbent operable to remove at least a portion of the sulfur present to produce a trimmed stream. The trimmed stream is then separated into a gas and a liquid streams, and the liquid stream is separated into a water stream and an upgraded hydrocarbon product stream.

  • Patent number: 8524074
    Abstract: The invention is directed towards a method of removing mercury bearing species from a hydrocarbon containing fluid. The method comprises the steps of: i) adding dithiocarbamate polymer to the fluid in an amount such that the number of mercury bonding sites on the polymer exceeds the amount of mercury atoms by at least 10% and ii) removing the mercury bearing dithiocarbamate polymer with a water/oil separation device. The invention relies upon an unexpected reversal in the solubility of dithiocarbamate polymer at very high concentrations. Because of the high solubility the polymer remains within the water phase of the hydrocarbon fluid and can be removed without the need for cumbersome precipitation methods and complicated solid liquid separation devices. As a result, the invention allows mercury contaminated crude oil to be easily rid of its mercury with easy to use equipment already present in a typical oil refinery.

  • 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.

  • Patent number: 8475652
    Abstract: A method for purification of uncatalyzed natural fuels in liquid state from metal ions by removing at least one compound selected from the group consisting of natural occurring contaminating porphyrins, metalloporphyrins, chlorins and naturally occurring degradations products of these compounds, such as petroporphyrins, containing said metal ions from the fuels. At least one hemeprotein in apo-form selected from the group consisting of globins, peroxidases, pyrrolases and cytochromes having high affinity for porphyrins is added to the fuels. The hemeprotein is mixed with the fuels in such a way that the porphyrins is bounded to the hemeprotein. The hemeprotein with bound contaminating porphyrins is removed so as to obtain purified fuels. The invention relates also to the use of at least one hemeprotein selected from the group consisting of globins, peroxidases, pyrrolases and cytochromes having high affinity for porphyrins for the purification of uncatalyzed natural fuels in liquid state from metal ions.
