In a wet scrubber water is introduced into dust laden off-gas in order to capture the fine dust particles. The scrubbing process comprises a whole set of phenomena like droplet break-up, coalescence, liquid wall film and dust capturing. We introduce a comprehensive simulation model is where representative droplets are traced in a Lagrangian manner while the dust is treated as passive Eulerian phases. The wall film is considered by a model solving the shallow water equations, including models for droplet deposition, film separation and film stripping. Numerical results for pressure drop and capturing efficiency are in good agreement with measurements.
