Flue gas resulting from incineration of garbage, refuse or residual materials contain among other components considerable amount of hydrochloric acid. GEA Messo AG offers complete processes and plants for treating this contaminated waste water. These systems are built for recovery or discharge of the following components:

  • Sodium chloride
  • Calcium chloride
  • Inorganic mixed salts
  • Hydrochloric acid

GEA Messo AG has supplied a large number of plants for waste water from flue gas cleaning with application of the following evaporation and crystallization technologies:

  • Multiple effect
  • Thermal and mechanical vapour recompression
  • Evaporative crystallization
  • Vacuum cooling crystallization
The most common evaporator and crystallizer types used are: flash, rising film, falling film and forced circulation evaporator as well as the forced circulation type crystallizer. GEA Messo AG has extensive know how and experience in designing the components in special material of construction like carbon steel, rubber lined, special alloys, graphite, plastic materials such as FRP, FEP and silicon cast iron etc.
