  • Numerical modelling of sulfur dioxide absorption in water droplets as an advanced design tool for emission mitigation [Elektronski vir]
    Besenić, Tibor ...
    Forthcoming tightening of the legislation concerning the sulfur dioxide emissions in marine and stationary applications will necessitate improvement of technical solutions for pollutant removal. Flue ... gas desulfurization in spray towers is an efficient removal method where the liquid is sprayed in a stream of rising gases, removing pollutants due to the concentration difference between gas phase and droplets. A lumped-parameter model for water droplets has been developed in order to describe the complex physical and chemical interactions during the exposure to flue gases. The main factors affecting the absorption are the mass transfer of pollutants through the gas-droplet interface and the aqueous phase chemistry in droplet. Mass transfer coefficient , which has been modelled with several approaches, is the most significant parameter regulating the absorption dynamic into the droplet, while the in-droplet chemistry regulates the maximum quantity of dissolved pollutants. Dissociation of sulfur dioxide and the chemical reactions in seawater have been described by the equilibrium reactions. Afterwards, the influence of mass transfer coefficient has been investigated and the model has been validated against the literature data on a single droplet scale. Obtained results are comparable with the experimental measurements and indicate applicability of the model for the design of industrial scrubbers.
