Pumping Energy: Pump as Turbine (PaT) system provides energy recovery with limited investment

摘要

Depressurizing a fluid by throttling it through a pressure reduction valve wastes energy. Conventionally, it is possible to use an expansion turbine to recover the energy stored in the fuel. A more cost-effective approach, however, is to use a pump with inverted flow that can function as a turbine. GE Oil & Gas/PVS, leaning on its experience with hydraulic pump recovery turbines (API pumps), has certified its Pump as Turbine product as a stand-alone energy generator, which is suitable for refineries and petrochemical operations, as well as heavy-duty operation.
