City gas supplying humidity control refrigerating system

Manufactured gas may corrode the pipe or cause an accident if the gas is cooled in the pipe and the water is condensed into the pipe wall. Therefore, it is necessary to cool the gas down to the seasonal dew point temperature to dehydrate it before supplying it. Gas manufacturing devices other than the low-pressure cooling method can be used to reduce cooling loads and operating costs.

Characteristics

  • Selection of moisture separator is important
  • High-accuracy controls should be used to prevent the gas temperature from dropping below 0°C to prevent the cooling system from freezing water in the gas
  • Refrigeration system has better solution type than dry type
