  FAP DEAERATORS CHARACTERISTICS
  The contact surface in FAP deaerators is maximized by the use of spray nozzle(s) and duration of contact is optimized in the heating trays. Heating of water is accomplished by direct contact of the water and the steam.
The solubility of a gas depends on the Temperature of the water and the partial pressure of the gas in contact with the water. When the temperature of the water is at the boiling point for the operating pressure, the solubility of the gases will be zero.
Repeated agitation and breaking up of the water by passing it through sprays and over trays and also through a steam atmosphere, which is maintained by venting, causes rapid diffusion and elimination of the gases.
 
Vacuum Deaerators
Vacuum type deaerators are used to obtain a very efficient carbon dioxide removal as well as a good oxygen removal from demineralized water. Single or multiple stages vacuum deaerators are available.
