A concise one-dimensional thermal-hydraulic two-fluid model is presented for the
numerical prediction of sulphur dioxide absorption from the flue gas onto drops of the waterlimestone
slurry in the vertical spray tower absorber. The model is based on mass, momentum and
energy balance equations for each phase separately, i.e. downward falling droplets of water-limestone
slurry and upward flowing flue gas. The sulphur dioxide content in the flue gas is predicted by a
balance equation of the sulphur dioxide mass fraction in the flue gas. Interface transfer processes
between the flue gas and the droplets are determined by closure laws. The obtained steady-state
balance equations are transformed in a form suitable for a direct application of the numerical
integration method for the system of ordinary differential equations. The developed thermal-hydraulic
model is validated by comparing numerical results with available measured data at the large utility
absorber. The prese...nted results clearly show the dynamics of flue gas and droplets thermal-hydraulic
processes and their influence on the absorption process. The influence of liquid-to-gas ratio and
droplet diameter on sulphur dioxide removal efficiency has been investigated.
