Abstract: A support device for a bearing assembly includes a housing with a bore and a centerline and a bearing having a bore for receiving a rotatable shaft. The support device has an annular body disposeable within the housing bore and having a central axis and inner and outer surfaces extending circumferentially about the axis, the inner surface defining a central bore for receiving the bearing. One or more first integral spring portions extend generally between the inner and outer surfaces and have a first stiffness and one or more second integral spring portions are each spaced circumferentially from the first spring(s). The second spring extends generally between the inner and outer surfaces and has a second, greater stiffness. The body is adjustably angularly positionable about the body axis to adjust a position of the shaft axis with respect to the housing centerline when disposed within the support bore.

Abstract: Rotor structure for a turbomachine, such as a centrifugal compressor is provided. Disclosed embodiments make use of venting/sealing arrangements effective for venting a tie bolt rotor so that, for example, an incipient leakage of a process fluid can be monitored. Additionally, in operation disclosed embodiments are effective to, for example, convey to the tie bolt a pressurized sealing fluid effective for reducing the likelihood of process fluid escaping to the atmosphere.

Abstract: A turbomachine type chemical reactor for processing a process fluid is presented. The turbomachine type chemical reactor includes at least one impeller section and a stationary diffuser section arranged downstream. The impeller section accelerates the process fluid to a supersonic flow. A shock wave is generated in the stationary diffuser section that instantaneously increases static temperature of the process fluid downstream the shock wave for processing the process fluid. Static pressure of the process fluid is simultaneously increased across the shock wave. The turbomachine type chemical reactor significantly reduces residence time of the process fluid in the chemical reactor and improves efficiency of the chemical reactor.
