Abstract: A gas-water separation system may be used for removing water from a wet gas compressed in a water-injected contact-cooled gas compressor. The gas-water separation system may include a tank constructed to hold a quantity of water; a heat exchanger coupled to the tank and constructed to extract heat from the water to chill the water when the water is present within the tank; an inlet port constructed to inject a flow of the wet gas into the chilled water when the water is present within the tank, the chilled water being operative to condense water vapor from the wet gas and reduce the dew point of the wet gas to yield a chilled compressed gas; a biological control system constructed to suppress biological activity in the tank; and a discharge port operative to discharge the chilled compressed gas.

Abstract: The present disclosure provides a compressor system operable for compressing a working fluid such as air. A conditioner is positioned upstream of the compressor to reduce the humidity and may in certain forms control a temperature of the working fluid entering the compressor. An aftercooler and an oil cooler is positioned downstream of the compressor. A first heat exchange system may direct water from a source through the conditioner to the aftercooler and oil cooler. An oil heat exchange circuit directs oil from the compressor to the oil cooler and then to a regenerator prior to reentry into the compressor. A control system is operable for controlling portions of compressor system to provide inlet air to the compressor at a desired temperature and humidity.

Abstract: A compressor includes a rotor having an outer compression surface and a plurality of inner heat exchange surfaces. A coolant supply manifold fluidly connects with a coolant inlet in a first axial end of the rotor, and delivers coolant fluid by way of conduits having an axial distribution in the rotor so as to deliver coolant fluid to the heat exchange surfaces. The coolant may be a refrigerant that undergoes a phase change within the rotor.

Abstract: The present disclosure provides a compressor system operable for compressing a working fluid such as air. A conditioner is positioned upstream of the compressor to reduce the humidity and in some embodiments may control a temperature of the working fluid entering the compressor. A working fluid aftercooler and a lubricant cooler is positioned downstream of the compressor. A first heat exchange system directs water from a source through the conditioner and then to the aftercooler and oil cooler in parallel. A second heat exchange system directs oil from the compressor to the oil cooler and then to a regenerator prior to reentry into the compressor. A control system with one or more control valves is configured to provide oil to the compressor at a target temperature defined to ensure that the temperature of the discharged compressor is above a pressure dew point temperature.

Abstract: A fluid expander is disclosed as used in conjunction with an air compressor that is driven by a prime mover. The fluid expander is structured to extract useful work from a fluid stream and add that work to the work provided by the prime mover to the compressor. In some embodiments a clutch can be used to decouple the expander from the compressor if insufficient work is developed by the expander. A gear train can also be used to change the rotational speed prior to work being delivered to the compressor.

Abstract: An integrated power generation system is provided. The system includes an heat source that produces a first gas flow to power a turbine operatively coupled to a compressor. The first gas flow can also heat a feedwater flow passing through a boiler. The compressor can produce a second gas flow that may be divided in two portions, the first portion flowing back to the heat source and the second portion flowing to an end user. Also, the second portion may be routed through an air cooler to dissipate heat to the feedwater flow to cool the second portion as well as preheat the feedwater flow prior to entering the boiler. The first portion can also exchange heat with the first gas flow exiting the boiler prior to the first portion entering the heat source. The boiler operation and the compressor operation are operable independently or concurrently.
