The rate of CO2 absorption rabs is defined according to eq. (1) as the increase in solvent loading 'D per unit time
of contact between the gas and falling droplet. Therefore, after each experiment the initial CO2 loading of the
solvent feed is analysed as well as the loading of the collected droplets sample. CO2 loadings are determined by
expelling all CO2 from the solvent sample by addition of a surplus of hydrochloric acid. The weight loss due to
degassing of CO2 is recorded with a precision balance.
