What should the moisture content be below in mg/m3 before waste gas adsorption treatment? ? ?
These different systems vary greatly; the key is to consider the adsorption capacity of the adsorbent and the relevant requirements.
In principle, the lower the water vapor content, the better, as the adsorbent will also absorb moisture. However, if there is a scrubber tower upstream of the adsorption tower, the exhaust gas exiting it will be at saturated humidity. To remove moisture, condensation is required, which involves a large amount of ice water and may not be cost-effective.
Is using a demister not very effective? ? ? What methods can be used to remove moisture? ? ?
A demister utilizes collision to remove only particulate water droplets; since saturated water vapor is in gaseous form, a demister cannot remove water in the gas phase. To remove water vapor from the gas phase, condensation can be used to condense the water vapor. However, for water to change from the gas phase to the liquid phase, heat exchange of latent heat is required; the value of this latent heat is quite high, which necessitates a large amount of ice water.
