Sulfur dioxide removal in coal Slurry reactor

Abstract EN

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 / vmin.

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.
