Chemiewerk Bad Köstritz GmbH

Installation of an absorption refrigeration system for SO2 liquefaction. In this plant, the ago congelo® is used to liquefy sulphur dioxide (SO2) from a process gas flow by cooling it directly in the evaporator to -55 °C. To do this, the ago congelo® utilises the waste heat generated during sulphur combustion and is thus part of the process plant, which produces other sulphur compounds in addition to SO2.

Technical data:

  • Coolant temperature: -55 °C
  • Cooling capacity: 353 kW
  • Heating capacity: 1,070 kW
  • Heat ratio: 0.33
