Gas phase amine depletion created by aerosol formation and growth

For MEA, as a relatively volatile solvent it is seen that gas phase depletion already takes place at number concentrations above 105 droplets/cm3 with an initial droplet radius of 1.5 μ and 5 M MEA initial concentration. For initial droplet radius 0.15 μ and 0.0001 M MEA initial concentration, which may be a more realistic case, hardly any depletion effect is seen up to 107 droplets/cm3. With change in amine volatility it is seen that the gas phase depletion effect is significantly stronger in the case of low volatility than for MEA at high droplet number concentrations. It is found that gas phase amine depletion has a strong effect on droplet growth.
