Degasser Tower

Degasser breaks weak carbonic acid into carbondioxide and water. The unit operation used is stripping. The weak acid, either from weak acid cation or strong acid anion is introduced from the top of the degasser column. The Degasser column has ballrings to increase the contact area.Air is blown from the bottom of the degasser tower. The air will split the Carbonic acid into carbondioxide and water , Co2 will be vented of from the degasser tower and the water will be collected in a tank. Degassed tower considered in a DM water system or in D Alclysing system when the alcalynity in the water is very high and the pay back of degasser tower is favorable.
