Carbon Dioxide Stripping, The 'Apparent' Mass Transfer

In principal, the basic equations for aeration oxygen mass transfer apply to carbon dioxide stripping CO2 mass transfer. However, in detail, they are very different. Firstly, the solubility of CO2 at 25 oC and 1 bar is 33 mmol/L, more than two orders of magnitude greater than that of oxygen in air 0.2 mmol/L, i.e. Henry's Law constant is
