Condensate Polishing Products

Condensate polishing normally applies to the treatment of condensed steam from turbines operating in the power industry.  It can also be applied to condensed steam from any steam system being returned to the boiler.  
The ultimate goal is to remove all soluble impurites and protect the high pressure boilers. These contaminents can come from many sources:

  • Cooling water from condenser in-leakage and this can be a particularly severe problem where sea water cooling is employed.

  • Make-up water, this can arise from maloperation such that regeneration chemicals enter the system, plant over-run during the service cycle or complete removal of certain substances such as organic matter may not occur.
  • The conditioning chemicals used to protect the circuit e.g. ammonia, morpholine and hydrazine can be regarded as sources of contamination if they are to be removed by the condensate purification plant.
  • Insoluble impurities will usually be the corrosion products from the materials in the system with copper and iron are the predominant species.
