The term De-Aeration refers to a specific process utilized to remove carbon dioxide as well as dissolved oxygen from a water stream. Typically associated with boiler feed water systems and utilized as a method to remove Carbon Dioxide (CO2) and Oxygen (O2) from the water prior to entering the boiler. The Decarbonation system also removes Carbon Dioxide (CO2) from the water and typically does not target the removal of Oxygen (O2). A De-Aeration system utilizes steam which enters at the bottom of the tower. The inlet feed water is heated, as close to saturation temperature as possible utilizing a minimum pressure drop and a limit on the vent. This ensures the best thermal operating efficiency of the tower.
The Decarbonation tower utilizes a counter current of air generated by a blower and enters into the tower also at the bottom and travels upward unless the system is an “Induced Draft” system and then the blower is located at the top of the tower and it pulls air up and through the unit. Both types of systems utilize an internal distribution system as well as a media packing to enhance the removal of the dissolved gases.
