Degasser Towers for Reliable Gas Removal in Water Treatment
A degasser tower is a tower vessel used in the process industry to remove dissolved gases, like oxygen, carbon dioxide, and hydrogen sulfide, from liquid, normally water or process fluid. Towers are located mostly in the gas and oil industry, water treatment plants, and chemical plants.

How It Works
The most notable unit in demineralization systems is the degasser tower, which is usually situated between cation exchange and anion exchange units. The main role of the degasser tower is to remove carbon dioxide when carbonic acid dissociates after cation exchange.

Made of such materials as coated mild steel or fiber-reinforced plastic, the tower can resist harsh working conditions. The low-pressure air stream is found at the base of the tower. The air moves upward through the liquid and strips away excess gases from the system. The water that has been purified after draining excess carbon dioxide is held in a sump at the unit’s base.

These gases must be eliminated since they have the potential to cause corrosion, scaling, or reduce the efficiency of downstream equipment. Improved process performance and equipment safety are maintained in the long term by the degasser.

Standard models are offered for supply of flow rates of 4 to 200 cubic meters per hour and the capacity to eliminate concentrations of carbon dioxide up to 200 parts per million. Special high-flow-rate customized models can be provided with flow rates of up to 1000 cubic meters per hour, which are most suitably utilized in processes with higher loads of carbon dioxide.
