PRS Pressure Reducing and Desuperheating Stations

ECONOMIC BENEFITS OF PRESSURE REDUCTION:

  1. LP steam has higher latent heat and can tend to reduce the amount of steam produced by the boiler, ie higher efficiencies.
  2. All steam equipment have a MAWP - maximum allowable working pressure. A PRS is used so that safe working pressures are not exceeded downstream of the PRV.
  3. Less flash steam is lost if the plant is operated on LP steam. Reduced pressure lowers the temperature of the downstream pipework and reduces radiation losses.
  4. The temperature of saturated steam varies with the pressure, so this also provides a simple method of controlling temperature of steam going to a process.
  5. For the same output, LP steam equipment may be larger, but is still cheaper as it follows a lower design specification.
  6. Plants are normally built in stages. Starting with the HP stage, we flash HP condensate and use the LP flash steam in the LP stage. This saves energy. At times the flash steam being generated is not enough and a PRV is used to maintain continuity of supply in the LP system.

PREDU – Self Operated Pressure Reducing Valve

Simply the easiest way to reduce pressure

A fully mechanical Pressure Reducing Station (PRS) is simpler to engineer, purchase, install and operate. But 'simple' should not mean unreliable, inaccurate or difficult to maintain. Our PREDU offers excellent accuracy, bullet proof reliability, and easier operation than any comparable product out there.

Application: Industrial installations, processing technology, plant manufacturing, etc.
