Cooling water treatment with CO2

Tuning the pH with gases & right equipment

GAS APPLICATION

Instead of sulphuric acid, CO2 is used to adjust the pH value in the cooling water. PH control with CO2 has many advantages. CO2 is non-corrosive and inert. Compared to mineral acids, the handling of CO2 is therefore easy and safe. In water, CO2 is a weak acid and therefore there is no risk of over-acidification of the cooling water. The use of CO2 prevents enrichment of sulphate in the water, which is helpful for the discharge permit of the blow down water. At the same time it preserves the buffering alkalinity from make-up water. Both aspects contribute to prevention of corrosion in the cooling system. The consumption of CO2 is calculated for each application from the operating parameters, such as the pH set-point, number of cycles of condensation and the quality of the added water.

 

Advantages of using carbon dioxide at a glance:

Easy and safe adjustment pH value without hyper-acidification  
Safe to use, no handling of dangerous, aggressive acids
Reduces corrosiveness of cooling water  
Lower salt content in blow down water
