  • Patent number: 7678263
    Abstract: High rate gas stripping for removal of sulfur-containing components such as mercaptans from crude oil may be conducted by feeding sweet gas to the bottom of a tower containing pre-heated mercaptan-containing crude oil feed. The gas bubbles up through the crude becoming enriched with H2S, mercaptans, CO2 and/or hydrocarbons. The rich gas exits the tower, and is treated to produce a sweetened gas, a portion of which is recycled to the tower, and an acid gas. The remainder of the sweetened and/or the acid gas may be used as a fuel or processed to recover a portion of any hydrocarbons that may have been stripped out of the crude oil with the mercaptans, sulfur-containing components, CO2, used for enhanced oil recovery or disposed.

  • Publication number: 20090151390
    Abstract: An LNG facility employing an enhanced fuel gas control system. The enhanced fuel gas control system is operable to produce fuel gas having a substantially constant Modified Wobbe Index (MWI) during start-up and steady-state operation of the LNG facility by processing one or more intermediate process streams in a fuel gas separator. In one embodiment, the fuel gas separator employs a hydrocarbon-separating membrane, which can remove heavy hydrocarbons and/or concentrate nitrogen from the incoming process streams.

  • Publication number: 20090126401
    Abstract: A liquefied natural gas facility employing a heavies removal column having multiple reflux streams. The reflux streams can have different compositions and can be operable to reduce the critical pressure of the fluids within the heavies removal column in order to permit the column to operate at higher pressures without adversely affecting the horsepower requirements of plant compressor/driver systems.

  • Publication number: 20080264099
    Abstract: An LNG facility capable of producing a domestic gas product from an intermediate stream in the LNG facility. Withdrawing the domestic gas product from a location within the LNG facility can minimize operational disturbances typically caused by extracting a domestic gas product stream upstream of the liquefaction portion of the LNG facility. In addition, withdrawing the domestic gas product from this location can provide increased control of light contaminants (e.g., nitrogen) in open-loop refrigeration cycles and can ultimately result in incremental LNG and/or NGL production.

  • Publication number: 20080115530
    Abstract: A system for removing a contaminant from a refrigerant stream employed in a closed-loop refrigeration cycle of an LNG facility. The system employs a distillation column to separate the refrigerant stream into a contaminant-rich and a contaminant-depleted stream, wherein the contaminant-depleted stream is subsequently returned to the closed-loop refrigeration cycle. The distillation column can include a reboiler and/or condenser. The reboiler and condenser can utilize one or more process streams from within the LNG facility to provide heating and/or cooling to the distillation column.

  • Publication number: 20070001668
    Abstract: Position sensing of movable elements including but not limited to machine components is disclosed. Motion of a movable element can produce motion of a magnetic field, which can be detected by magnetic sensors. The motion and/or variations of a magnetic field and/or a magnetic flux may be produced by any combination of a motion of the sensors, associated magnets, or associated magnetic material. Magnetic sensors maybe capable of measuring either rotary, or linear motion, or both. Such sensors can provide indication of an incremental position change, an absolute position, or both. Absolute position and high-resolution position sensing may be produced for measurement of either linear and/or angular motion. Suitable magnetic sensors include, but are not limited to, Hall effect devices and/or magneto-resistive elements, and may include multi-element magnetic sensors. Suitable signal conditioning and/or control means such as control electronics can be used to receive output signals from the sensors.

  • Publication number: 20060101930
    Abstract: Methods and apparatus are disclosed for providing reduced friction in drive screw assemblies, including electromechanical actuator (EMA) assemblies. A drive screw assembly is disclosed that includes a drive shaft, a drive screw, and a screw head. A stationary guide collar having a guide bore and a support surface receives the screw head or a portion of the drive screw. The guide collar may be fixed in angular relation to the screw head. As the screw head moves on a linear path during rotation of an associated drive shaft, a supported surface slides in only linear motion with respect to the support surface of the guide collar and as a result friction forces due only to linear motion are generated. Rotational friction forces and associated efficiency and power losses are consequently reduced or eliminated in the drive screw assembly.

  • Publication number: 20050258786
    Abstract: A brushless DC motor apparatus includes a housing and a stator assembly coupled to the housing. The apparatus further includes a magnetic rotor assembly rotatably coupled to the housing. The magnetic rotor assembly is configured to rotate within the housing in response to electric currents through windings of the stator assembly. The apparatus further includes position sensors which are configured to provide position signals identifying angular position of the magnetic rotor assembly relative to the stator assembly. Each position sensor includes (i) a Hall-effect sensor disposed distally from the windings, and (ii) magnetic circuit members having first end portions adjacent the windings and proximate rotor magnets and second end portions adjacent the Hall-effect sensor. Use of such magnetic circuit members enables the Hall-effect sensors to reside a greater distance from the windings vis-à-vis conventional brushless DC motors which position sensors adjacent to stator coils within motor casings.

  • Publication number: 20050200328
    Abstract: Oscillation and other disturbance damping is provided for a system having a load driven by an electric motor, e.g., an electromagnetic actuator. Damping is achieved using feedback in an active mode, where power is supplied in a normal operation mode of the electromagnetic actuator. Feedback may be provided by measured force (or torque) transmitted between the actuator and load mass. A gear train or other mechanical advantage device may be connected between the electromagnetic actuator output and load, this combination forming an electromechanical actuator (EMA). Instead of force or torque, acceleration of the load may be used as a feedback signal. In one embodiment, active mode damping uses the motor's actual current as a feedback signal. In certain or all active damping versions of the invention, a high pass filter is preferably used to receive feedback signals and filter out low frequency feedback. Alternatively, damping is achieved in an inactive (passive) mode of motor operation, e.g.

  • Patent number: 5536643
    Abstract: A method for the non-radioactive determination of circulating red cell volume, total blood volume and red cell survival. Red blood cells are biotinylated and injected into the subject for dilution in the subjects total blood volume. A diluted sample is extracted and incubated with a label, either a radionuclide or a fluorescent moiety complexed with avidin or streptavidin. Detection of the label, as for example by gamma counting in the case of a radionuclide or fluorescence activated cell sorting in the case of a fluorescent moiety, allows calculation of the red cell volume and therefrom, total blood volume. Sequential measurements are possible with this method. Aspects of the method include enhanced biotin labeling and separation of cells by density gradient means.
