Deionization of boiler feed water using an ion exchanger

Product applications

Deionization of boiler feed water using an ion exchanger

In steam boiler systems, salts that have dissolved in the water lead to corrosion and deposits. To avoid corrosion and deposits, depending on the operational mode and design of the steam generator, there are important requirements regarding the quality of the boiler feed water. In a deionization system, the salts that have dissolved in the water are removed using ion-exchange resins. These salts are dissociated, i.e. in positive (cations) and negative particles (anions), and as a result, a so-called desalination line is set up as follows: cations exchanger – CO2 degasifier – anions exchanger – mixed-bed fi lter. Moreover, for the installation to operate properly, a regeneration station and neutralization are required.
