The easiest way to deaerate is to force steam into the feedwater, this action is called scrubbing. Scrubbing raises the water temperature causing the release ... O gases that are then vented from the system. In boiler systems, steam is used to "scrub" the feedwater as (1) steam is essentially devoid [of O2 ... and Co2] (2) steam is readily available and (3) steam adds the heat required to complete the reaction. For efficient operation, deaerating equipment must satisfy the following requirements: (1) Heating of the feedwater: The operating temperature in the unit should be the boiling point of water at the measured pressure.  1, fiche 1, Anglais, - deaerating%20equipment
