Extending the life of your ion exchange resin in boiler feed water applications

Did you know that when producing steam, that it is most effectively accomplished by utilizing a decarbonation process? Decarbonation and Degasification is the most economical way to process in fluent water pre-Ion exchange treatment through a vertical packed tower called a decarbonator or often times referred to as a degasifier.  This is the most economical method to remove carbon dioxide (CO2) and Hydrogen Sulfide (H2S) to prevent the formation of carbonic acid and other corrosive conditions is Degasification and Decarbonation which will extend the life of the ion exchange resin.  If CO2 levels remain high in the inlet feed water to the ion exchange system the resin beds whether cation or anion will require more frequent regeneration and your chemical usage and cost will rise.

In industrial applications it’s easy to overlook,

and often there is not enough focus on the need to select the right type of decarbonation or degasification system to assure that the process water treatment system will perform at the highest optimal level.  For water filtration when the primary process is membrane filtration of as often referred to “reverse osmosis”, too little attention is given to the need to properly remove CO2 from the process to lower the pH and adjust the alkalinity.
