DefinitionA <HYDRAULIC POWER RECOVERY TURBINE>, also referred to as HPRT, is a <HYDRAULIC TURBINE> that is used in a process when a fluid is pressurized and must be reduced in pressure. Rather than throttle the fluid pressure though a pressure reducing valve (PRV) and waste the stored energy, a PRT can be used to drop the fluid pressure and turn the turbine impeller and drive a generator or drive shaft to another process.
