HPRT Hydraulic Power Recovery Turbine

Efficiently utilize energy during liquid transport

Installing a Shin Nippon Machinery's hydraulic power recovery turbine when transporting liquid from high pressure to low pressure enables more efficient utilization of energy by extracting rotational power from liquid pressure.

In oil refineries and petrochemical plants, after raw materials are sent to react or decompose in high-pressure tanks, the products of these processes are commonly returned to lower-pressure tanks. When fluids are transferred to high-pressure tanks, pumps impart energy to the fluid; however, that same energy is wasted if pressure-reducing valves or other throttle mechanisms are used when transferring fluids back to low-pressure tanks. 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.

Although we call these hydraulic power recovery turbines, their basic architecture is no different from a pump. The difference is that the direction of fluid flow is completely opposite to that of a pump. An HPRT sends high-pressure fluid to the discharge nozzle and out of the suction nozzle, applying turning force to the impeller in the reverse direction, which can be collected as power. For this reason, most devices sold as pumps can also be utilized as hydraulic power recovery turbines.

SNM also manufactures a hydraulic power recovery turbine, thus helping companies around the world conserve energy to prevent combat global warming.
