  • Patent number: 9102534
    Abstract: A process for reducing CO2 emissions from combined cycle power generation processes utilizing a gaseous hydrocarbon feed, which includes splitting the hydrocarbon feed into two portions; a first portion ?45% by volume of the feed and a second portion ?55% by volume of the feed, feeding the first portion to an autothermal reforming process to generate a hydrogen-containing gas and a carbon dioxide stream, combining the hydrogen-containing stream with the second portion, combusting the resulting hydrogen-containing fuel stream with oxygen containing gas in a gas turbine to generate electrical power and passing the exhaust gas mixture from the gas turbine to a heat recovery steam generation system that feeds one or more steam turbines to generate additional electrical power. The captured carbon dioxide stream may be fed to storage or enhanced oil recovery processes. The process may be retrofitted into existing combined cycle processes.

  • Patent number: 8973441
    Abstract: Embodiments of techniques and technologies to verify the interference fit of fasteners are disclosed. In one embodiment, a transducer is positioned to transmit a shear ultrasonic signal through a region of a fastener which is subject to stress when the fastener experiences an interference fit. The shear ultrasonic signal is transmitted through a region of the fastener subject to the stress. As the transmitted ultrasonic signal encounters the region, it is mode converted corresponding to a degree of interference which the fastener is experiencing. A return ultrasonic signal from the fastener is received with the transducer. From the return ultrasonic signal, a processor determines the degree of interference fit which the fastener is experience and outputs an indication of the same.

  • Patent number: 8859631
    Abstract: A process is described for the conversion of synthesis gas into hydrocarbons including the steps of; (i) passing a synthesis gas comprising hydrogen and carbon monoxide over a cobalt catalyst at elevated temperature and pressure to produce a first reaction product mixture comprising hydrocarbons, steam, carbon monoxide and hydrogen, (ii) condensing and separating water from the first reaction product mixture to produce a de-watered first reaction product mixture, (iii) passing the de-watered first reaction product mixture over a supported ruthenium catalyst at elevated temperature and pressure to produce a second reaction product mixture containing hydrocarbons, and (iv) recovering the hydrocarbons from the second reaction product mixture.

  • Patent number: 8840188
    Abstract: Horizontally movable arm pads are useful for, among other things, their ability to be ergonomically positioned. An arm pad comprises a pad cover and a pad pan and is attached to an arm support. In one embodiment, a pad is laterally movable with respect to the arm support. In another embodiment, a pad is capable of moving forwards and backwards. In yet another embodiment, a pad is capable of moving laterally and forwards and backwards.

  • Patent number: 8703076
    Abstract: A catalyst unit suitable for loading into a tube in a reactor includes a plurality of catalyst particles incorporated within a removable solid matrix, said unit in the form of an elongate body in which the particles are packed together such that the volume shrinkage upon removal of the removable matrix is ?20%. The catalyst particles preferably comprise one or more metals selected from the group consisting of Fe and Co in oxidic or reduced form. The units are particularly suitable for loading catalyst into tubes in a Fischer-Tropsch reactor.
