    Abstract: An automatic control of clamping forces in primary nozzle systems of radial turbines. Pressure to an closed annular volume positioned between a turbine housing and an axially adjustable mounting ring is varied to regulate the clamping forces against inlet vanes which form primary nozzles. A controller compares process control data with a signal indicative of operational deviation from nominal operation as indicated by the process control signal to detect onset of excessive blow-by, in which case pressure is increased in the closed annular volume to move the mounting rings closer together. The controller also compares expected and actual system data to detect onset of excessive clamping, in which case pressure is increased in the closed annular volume to increase clamping forces.

    Abstract: A refrigeration system employing a motor driven compressor with an associated turboexpander coupled to the motor of the compressor. The compressor draws incoming air through a heat exchanger and a dehydrator. The compressor discharges compressed air through a high temperature heat exchanger and the other side of the heat exchanger on the inlet side of the compressor. The compressed air is then expanded through the turboexpander and used for cooling. The high temperature heat exchanger is employed for hot water generation.

    Abstract: A turboexpander-generator system employing a housing with a rotatably mounted shaft oriented vertically with a turboexpander associated with the upper end of the housing and shaft, a generator associated with the housing and shaft below the turboexpander and a lubricant pump located at the lower end of the housing and shaft. The lubricant pump controls an actuator valve which controls the variable inlet nozzles to the turboexpander. Thus, a speed control system is achieved through use of the lubricant pump pressure. A seal gas separator is provided with two ports located in the turboexpander exducer at positions of different pressure. High pressure is used to provide a seal between the bearings and the turboexpander. Low pressure is directed to the area of the sump of the pump to enhance continuous lubricant return. A self-priming mechanism causes a reservoir to be charged during pump operation with return of the lubricant to the sump when the pump is off.

    Abstract: A seal-off mechanism for preventing migration of working fluid along a turbine shaft which includes a floating seal ring and a shaft shoulder. The seal ring is spring biased against the shaft shoulder. During turbine operation, a pressurized fluid moves the ring away from the shoulder. The pressurized fluid then flows toward the turbine to contain the working fluid. A chamber collects the pressurized fluid and the working fluid for subsequent separation and reuse.

    Abstract: A surge control system for a compressor comprising a bypass passage controlled by a bypass valve to return flow to the compressor inlet for avoiding surge in the compressor. The bypass valve is controlled through a sensing of a compressor speed and flow. The compressor speed and the square root of the flow signal, which is proportional to the actual flow, are presented as a ratio for comparison with an empirically established constant. When the conditions of the compressor system are such that the ratio approaches the constant, the bypass valve is opened and the compressor experiences increased flow therethrough.

    Abstract: A system for supplying lubricant under pressure to a rotary mounting system having bearings when the main pressurized lubricant supply system fails. The system includes a bladder or other expansible chamber in association with a lubricant reservoir. The bladder has a source of pressurized gas which is either inherently or through regulation maintained at a pressure below that of the main system and above that of the lubricant discharge from the bearings. The source of pressure for the reserve system may be pressure from a gas seal or from the rotor chamber of a pump or turbine. If regulated, the regulation may be by the main lubricant pressure or the pressure of the lubricant discharge. The system also contemplates accommodation for leaks and over pressures.

    Abstract: A system and method are disclosed for processing an oxygen-containing gas for use in a chemical process producing a generally inert gas. A fluid handling rotor is carried by a rotary shaft for effecting a pressure change in the oxygen-containing gas. A housing surrounds the rotor and the adjacent portion of the shaft. A bearing, axially spaced from the rotor, supports the shaft in the housing for rotation. Lubricant is injected into the bearing and is caused to flow through the bearing and axially toward the rotor. A seal surrounds the shaft intermediate the rotor and the bearing and seals between the shaft and housing. A generally inert seal gas is extracted from the products of the chemical process and injected into the seal under a pressure greater than the pressures within the housing on either side of and immediately adjacent the seal.

    Abstract: The invention comprises a rotary fluid handling apparatus having first and second coaxial bodies mounted for relative axial movement therebetween and having respective opposed radially facing annular surfaces. The bodies may be, for example, the stator of a turboexpander or compressor and a relatively rotatable clamping ring for a plurality of adjustable blades. A first seal including a sealing ring is disposed between and seals between the annular surfaces, and the apparatus defines a first pressure zone which communicates with one axial side of the seal. The first body has a first stop engageable with the sealing ring to permit the force exerted on the sealing ring by the pressure of the first zone to be transmitted to the first body. The second body carries a second stop engageable with the sealing ring to permit the force exerted on the sealing ring by the pressure of the first zone to be transmitted to the second body, and also to retain the sealing ring from force-transmitting engagement with the first stop. The second stop is further releasable to permit force-transmitting engagement between the sealing ring and the first stop.

    Abstract: A closed-loop system that dissipates energy from an expander and does not contaminate the expander. The noncontaminating energy dissipator has a closed-loop conduit that is connected to a compressor, a pressure reduction valve and a heat exchanger. A brake gas circulates in the closed-loop conduit from the compressor to the pressure reduction device, then to the heat exchanger and finally back to the compressor, where the process repeats. The use of an inert brake gas prevents interactions between the brake gas and a hazardous process fluid from forming an explosive mixture. The closed-loop conduit has an outlet so that the brake gas can be used for purposes other than circulating through the closed-loop. A make-up conduit and another control valve can be added to the noncontaminating energy dissipator so that brake gas that is lost through seals or other parts of the system can be readily replaced. The noncontaminating energy dissipator can be used to expend excess expander energy in such a way as to optimize the operation of the turboexpander.
