In this paper, absorption of SO2 emitted from coal combustion into water is taken as a reference. The relation between concentration of alkali slurries and removal of SO2 is presented with graphs. The SO2 removal efficiency for the slurry of sodium carbonate is greater than lime /limestone. It is observed from the experiments that sodium alkali sorbents have high reactivity relative to the lime and limestone. From the experimental data of n+1 data points, an n degree polynomial using Lagrange interpolation method is formulated and verified the experimental results and also found the maximum value of the removal of Sox with an optimal flow rate.
