Abstract: Chemical reactors (10) and methods crack hydrocarbons in process fluids by accelerating the process fluid to a velocity greater than Mach 1 with an axial impulse impeller (40) and generating a shock wave (90) in the process fluid by decelerating it in a static diffuser (70) having diverging diffuser passages (72). Temperature increase of the process fluid downstream of the shockwave cracks the entrained hydrocarbons in a single pass, through a unidirectional flow path (F), within a single stage, without recirculating the process fluid for another pass through the same stage. In some embodiments, the turbomachine chemical reactor (110) has multiple successive stages of one or more axial impulse impellers (40A, 40B), paired with a diverging passage, static diffuser (70). Successive stages crack additional hydrocarbons by successively raising temperature of the flowing process fluid.

Abstract: A centrifugal compressor (20), with a shaftless impeller (50), is rotatively mounted on a journal. The journal is incorporated within a stationary journal shaft (40) that spans the impeller hub (52), or in a journal stub (80) that projects into at least one of the axial ends of the impeller hub, or in a pair of opposed, first and second journal stubs (142, 146). A magnetic bearing (60) is interposed between the journal and a hollow hub of the impeller. The journal and magnetic bearing support and position the impeller hub within an impeller cavity of the compressor casing (22). An independent impeller drive (151) rotates the impeller. A drive shaft (150), which is independent of the journal, is coupled to the impeller. Respective drive motor (300), rotor and stator permanent magnets, and/or electromagnetic coils are embedded within the respective, opposing journal and hub.

Abstract: Single-and multi-stage compressors independently drive impellers in each compressor stage with one or more electric motors that are incorporated in the compressor casing. In multi-stage embodiments, impellers in respective compressor stages are capable of being driven at different rotational speeds. In some embodiments, the electric motor is a ring-type electric motor, where the rotor is coupled to a circumscribing impeller. The rotor in turn circumscribes the stator. In other embodiments, the electric motor is a flat or pancake-type electric motor, where its rotor is coupled to an axial sidewall of the impeller, and its stator is disposed axially outboard of and in opposed relationship with the rotor body. In some embodiments, the compressor stage incorporates a pair of flat or pancake-type electric motors. In some embodiments, rotors of the electric motors have permanent magnet-type rotor magnets, while in other embodiments the rotor magnets are electromagnetic rotor magnets.

Abstract: Compressors achieve in a single stage a high-pressure ratio ( r ) of greater than or equal to 2.5:1 on a process fluid having a molecular weight of 12-20, such as natural gas. Two or more of the compressor stages are combined serially to increase overall pressure ratio. Each single-stage includes respective inlet and outlet passages and an unshrouded, centrifugal impeller that includes a plurality of impeller blades. Process fluid is discharged from trailing edges of the impeller blades at a rotational velocity greater than or equal to 1400 feet/second into a diffuser passage of the outlet. Dimension ranges of the annular diffuser passage, the centrifugal impeller, and the diffuser vanes vary as a function of pressure ratio ( r ) and/or the flow coefficient (φ) of the process fluid flowing between the inlet and the outlet.
