The HPRT may be used to drive a pump, generator, compressor or other rotating machinery. Speed is governed by the inlet control valve, motor or generator and the electrical grid frequency. If required, a one-way clutch between a motor and the HPRT prevents the HPRT from robbing power from the train under low flow startup conditions.

All centrifugal pumps from low to high specific speed, whether single or multistage, horizontal or vertical, can be operated in reverse and used as a HPRT. High specific speed pumps (axial flow) are used for lower head und higher flow, single stage or multi stage radial flow pumps are used for higher heads and lower flow.

For high flows and lower pressure differential, mixed flow, or axial flow (propeller) type verti-cal pumps may be used as HPRTs. You set out the challenge, we present the solutions. The HPRT may be used to drive a pump, generator, compressor or other rotating machinery.

Installing a hydraulic power recovery turbine (HPRT) when transporting fluids from high pressure to low pressure enables more efficient utilization of energy by extracting rotational power from liquid pressure.

HT series hydraulic power recovery turbine through high pressure liquid driven turbine rotation to convert the pressure energy into the rotor kinetic energy driving equipment, so that the liquid in the device rich pressure can be recycled. All kinds of centrifugal pumps can be reformed into HPRT after the technical improvement of key parts.

2017年6月1日 · The main HPRT equipment assembly includes the HPRT coupled to a generator or a pump. When used to drive a pump, the HPRT is typically not used as standalone driver, but rather in a train arrangement where the HPRT and a motor act as dual drivers, with the pump drive rotating at the motor speed, or at a greater than motor speed, as shown in ...

2022年8月1日 · Energy efficiency in urea plants through Hydraulic Power Recovery Turbines (HPRTs). Three HPRTs’ layouts, as well as four urea capacities, have been investigated. A numerical model is built in ASPEN PLUS® to resemble the urea synthesis process. The studied energy efficiency system allows recovering a maximum of 4,000 MWh/year.

A HPRT is defined as a device designed for the energy‐efficient on‐site transfer of liquid and such that it can operate in two modes of operation depending upon the physical flows of fluid required

1981年11月1日 · This paper will discuss the application of reverse running centrifugal pumps as power recovery turbines to recover up to 80% of that energy. The economics of Hydraulic Power Recovery Turbine (HPRT) systems are explored with respect to the equipment cost, operating costs and payouts for the different sizes of R.O. Systems.

2011年12月1日 · Hydraulic power recovery turbines can convert the excess pressure into mechanical shaft energy and increase the overall process efficiency. Here we see how reverse running pumps can be used as turbines as an economical solution to recover energy.
