Modern desalination processes for integrated water and power plants IWPP

Energy-efficient water purification for plant operation and third party supply

  • CT flowmeasurement for water intake and supply to 3rd party
  • Reliable instrumentation for highly corrosive thermal processes
  • Full solution supplier

Power plants which have no access to sweet river water or ground water need to gain water for plant operations from sea water. Sea water is available in large amounts but has a very high salinity of typically 35g/kg. The desalination processes, and the further treatment needed, is very costly, and the best suitable process varies according to the raw water quality and the availability of process heat. Three main processes for sea water desalination for power generation have been established: Sea Water Reverse Osmosis (SWRO), Multi-Effect-Distillation (MED) and Multi-Stage-Flash evaporation (MSF) - the last two make use of available process heat.

KROHNE can address all major process control instrumentation across the entire sea water desalination process. From the custody transfer measurement of raw-water to the analysis of demineralised boiler feedwater, to meet strict industry specs for conductivity, silica and dissolved oxygen. Industry specific solutions and products meet the particular requirements of the sea water desalination process like standards, materials, testing and documentation.
