  • Patent number: 9868914
    Abstract: Deep desulfurization of hydrocarbon feeds containing undesired organosulfur compounds to produce a hydrocarbon product having low levels of sulfur, i.e., 15 ppmw or less of sulfur, is achieved by hydrotreating the feed under mild conditions, and separating the hydrotreated effluent into an aromatic-rich fraction which contains a substantial amount of the aromatic refractory and sterically hindered sulfur-containing compounds, and an aromatic-lean fraction. The aromatic-rich fraction is contacted with isomerization catalyst, and the isomerized aromatic-rich fraction is recycled to the mild hydrotreating process.

  • Publication number: 20150068611
    Abstract: A method and chemical delivery system are provided. The method includes providing a vapor phase of a multi-component liquid source. The method further includes contacting a pre-loaded carrier gas with the vapor phase, wherein the pre-loaded carrier gas includes a carrier gas and at least one component of the multi-component liquid source and delivering a gas stream comprising at least one component of the liquid source to a critical process or application, wherein the amount of the component in the carrier gas is sufficient to keep the ratio of components in the multi-component liquid source relatively constant. The chemical delivery system includes a multi-component liquid source having a vapor phase.

  • Patent number: 8973613
    Abstract: An ER fluid valve includes a housing and a plurality of parallel flow passages through the housing each defined by spaced electrodes at least one of which is controllable independently of other flow passages electrodes. A controller is configured to selectively establish electrical fields for all of the independently controllable electrodes to close all of the flow passages to ER fluid flowing through the housing. By removing the fields from all of the independently controllable electrodes, all the flow passages are open to the ER fluid flowing through the housing. By establishing fields for select independently controllable electrodes to close their associated flow passages and by leaving other flow passages open, restricted flow of the ER fluid through the housing is accomplished to vary the flow rate through the housing.

  • Patent number: 8944084
    Abstract: In a method of moving droplets, local heat is applied to a surface portion of a droplet for an amount of time sufficient to create a Marangoni flow in the droplet. Droplets are suspended in an emulsion in a carrier liquid on a substrate. A laser beam is used to move one of the droplets. the droplet consists of a first substance and a carrier liquid consists of a second substance that is not mixable with the first substance. The droplet is placed in the carrier liquid, and the mixture is emulsified. The emulsified mixture is placed on a substrate. Then the local heat is applied to the surface of the droplet. The first substance may include oil and the second substance may include water.

  • Publication number: 20150027554
    Abstract: The disclosure relates to a droplet manipulating device and a method for manipulating a droplet. The droplets manipulating device includes a first magnetic field generator, a second magnetic field generator, and a flow channel. The first magnetic field generator produces a first magnetic field on the droplet, so that the droplet has the direction of magnetic field corresponding to the first magnetic field. Further, the second magnetic field generator produces a second magnetic field on the droplet so as to drive the droplet to be in motion in the flow channel.

    Abstract: Apparatuses and methods for urea dosing of an exhaust after treatment system are disclosed. Exemplary apparatuses include a chamber configured to receive pressurized gas at a first inlet, receive urea solution at a second inlet, and provide a combined flow of pressurized gas and urea to an outlet, a flow passage extending from the first inlet to a seating surface, and a valve member configured to move between an open position in which the valve member is spaced apart from the seating surface and a closed position in which the valve member contacts the seating surface. As the valve member moves from the open position to the closed position the valve member contacts the seating surface at a first location and wipes an area of the seating surface extending from the first location in a direction toward the flow passage.

  • Publication number: 20150020890
    Abstract: A method and apparatus, for supplying high-pressure mixed gas of a low-vapor-pressure first gas as an active gas and a high-vapor-pressure second gas, are arranged to reduce an amount of the first gas discarded. The mixed gas in a high-pressure state is supplied from a mixing container to a use point. Upon reduction of pressure in the mixing container to a setpoint as a result of supply to the use point, a predetermined amount of the first gas is charged into a replenishment container connected to the mixing container by a replenishment line having a replenishment valve, and which is evacuated. As the second gas is charged into the replenishment container charged with the first gas, the replenishment valve is opened such that the first gas in the replenishment container is forced out by the second gas, thereby charging the mixing container with the mixed gas in the high-pressure condition.
