Abstract
The invention is directed to an energy recovery pump turbine for use in industrial processes where a fluid is pumped at a high pressure to the process and at least a portion of the fluid is discharged from the process at a high pressure. A turbine is positioned to receive the high pressure discharge from the process. The turbine has an impeller positioned on a shaft and the discharged fluid engages the impeller and causes the impeller and shaft to rotate. A pump is position adjacent to the turbine to receive the fluid being pumped to the process. The pump has an impeller mounted on a shaft and the shaft of the pump is operatively connected to the shaft of the turbine. Rotation of the turbine shaft causes the impeller and the shaft of the pump to rotate whereby the pump assists in supplying the fluid under pressure to the process and to recover energy from the high pressure fluid discharged from the process. Also disclosed is a method for recovering energy from an industrial process 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. The high pressure discharged fluid is directed into the inlet of a turbine. The inlet of the turbine is caused to rotate by the high pressure discharged fluid. The turbine impeller is mounted on a rotatable shaft. An impeller of a pump that is mounted on the shaft is caused to rotate by the rotation of the shaft that is caused by the rotation of the turbine impeller. The fluid that is to be pumped to the process is directed to the inlet of the pump. The rotating impeller of the pump raises the pressure of the fluid supplied under high pressure to the process and recovers energy from the high pressure fluid discharged from the process.
