Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.

A bearing housing for use in a wind turbine is provided. Further, the bearing housing is axially coupled to a base support structure using plurality of fastening points on the bearing housing. The bearing housing may be coupled to the base support structure at multiple points so that the load is distributed evenly to the support structures such as base plate and the tower. The bearing housing is coupled to the base support structure using a fastener. The horizontal central axis of the bearing housing coincides with the horizontal central axis of the base support structure.

A compressor device includes a housing and a shaft supported for rotation within the housing. The compressor device includes a compressor section with a compressor wheel. Also, the compressor device includes a thrust suppression section with a chamber and a thrust balance body disposed within the chamber. Moreover, the compressor device includes a motor configured to drivingly rotate the shaft, the compressor wheel, and the thrust balance body. The thrust balance body divides the chamber into a first sub-chamber and a second sub-chamber. Additionally, the compressor device includes a bleed air system that fluidly connects the compressor section and the thrust suppression section. The bleed air system is configured to bleed air from the compressor section, through the first sub-chamber, to the second sub-chamber, pressurizing the first sub-chamber and generating a counterbalancing thrust load that counterbalances a compressor thrust load on the shaft.

An impeller for pumping fluid that comprises discharge flow paths that allow high pressure liquid to be used to flush out low pressure gas that can accumulate within the internal structure of the impeller. The impeller comprises transition regions, vanes, and at least one discharge flow path. The vanes are rotational about a central axis. The transition regions and the plurality of vanes have a high pressure flow path and a low pressure flow path. The at least one discharge flow path is in fluid communication with a section of the low pressure flow path of at least one of the transition region(s) and the vane(s).

A thrust box with improved cooling comprises a case having an interior, a first passageway and an opposing second passageway. A shaft passes through the case and the first and second passageway. A thrust runner is secured to the shaft and a pump ring is attached to the thrust runner. Advantageously, the pump ring facilitates oil rate circulation and cooling among other benefits.

A wind turbine mountable to a motor vehicle preferably includes a wind blade, a turbine housing, an electrical generator and an electrical power converter. The wind blade preferably includes a plurality of blade elements, a top plate, a bottom plate and a support shaft. The turbine housing includes a turbine base plate, a turbine top plate and a peripheral side wall. A top shaft rotary bearing is retained in the turbine top plate. The electrical generator includes a generator rotor and a generator stator. The generator rotor is retained in the base plate. The bottom shaft thrust bearing is retained in the turbine base plate. The generator stator is mounted to the turbine base plate. The electrical leads of the generator stator are connected to an input of the electrical power converter. The electrical power converter converts the 120 volt AC signal to a suitable DC voltage.
