Pratima Bajpai, in Biermann's Handbook of Pulp and Paper (Third Edition), 2018.Deaeration.Deaerationof water is accomplished by decreasing the concentration of the offending gas species (O 2, CO 2, NH 3, H 2 S) over the water sometimes with heating of the water, which decreases the solubility of most gases (e.g., Fig. 15.1 [Volume 2] for oxygen). This can be accomplished by applying a ...
