Patent ·
OSTI ID:5801309
This patent describes an energy recovery pump turbine for use in industrial processes where a fluid is pumped at a high pressure into the process and at least a portion of the fluid is discharged from the process at a high pressure. It comprises a central body portion that defines a turbine impeller cavity and a pump impeller cavity; a turbine inlet nozzle extending from the turbine impeller cavity through the central body portion; the turbine inlet nozzle being located adjacent the outer periphery of the turbine impeller cavity, a turbine exhaust passageway passing into the turbine impeller cavity, the turbine exhaust passageway being located adjacent the center of the turbine impeller; a turbine positioned in the turbine impeller cavity to receive the high pressure fluid discharged from the process, the turbine having an impeller positioned on a shaft, the fluid engaging the impeller and causing the impeller and shaft to rotate.
