Stripping works on the basis of mass transfer. The idea is to make the conditions favorable for the component, A, in the liquid phase to transfer to the vapor phase. This involves a gas–liquid interface that A must cross. The total amount of A that has moved across this boundary can be defined as the flux of A, NA. jane wicker death videoWebb11 apr. 2024 · This ratio is determined by the solubility of the gas pollutants, the abundance of pollutants and particulate matter in the gas stream, and the mass transfer characteristics of the tower.
