Non stationary model of wet limestone desulphurization plant was developed to study chemical and physical phenomena during operation. The absorption of SO2from flue gas to counter current falling dispersed drops of liquid phase, chemical equilibria of sulphate (IV), sulphate (VI), carbonate and calcium ions in solution, oxidation of sulphate (IV) to sulphate (VI), precipitation and dissolution of CaSO3and CaSO4, and dissolution of limestone as neutralizing agent were built into model. Based on various boundary conditions and model input parameters (e.g. plant dimensions) dynamical responses to chosen parameters can be calculated by model. It can satisfactorily predict SO2removal rate, chemical composition of the absorbing slurry, etc. It was verified on 3 MWe pilot plant at Šoštanj coal fired power plant. The model can be used as a tool for design, optimization in technology and for extrapolation of measured pilot plant data.
