The objective of this work was to study the feasibility of using coal
slurry for the removal of SO2 from simulated flue gas stream (air,
SO2). The effect of gas rate, temperature, and initial SO2
concentration on the overall removal efficiency was investigated at
wet and dry bed conditions. The results indicated that the optimum
gas rate was 60 l /min. The SO2 removal efficiency was highly
temperature sensitive, and increases with increasing the bed
temperature especially at wet bed conditions and decreases with
increasing SO2 initial concentration. A mathematical model for the
desulfurization process was proposed based on the material balance
for gaseous and solid phase streams. The model was found to give a
very good description of the experimental data with 95% confidence
level.
