Statistical modeling and optimization of a multistage gas-solid fluidized bed for removing pollutants from flue gases

- Statistical modeling correlated ΔP and Umf with operating parameters in a three-stage fluidizer.
- Model-predicted values of ΔP and Umf fitted well the experimental data.
- Umf in the top bed of a three-stage system was less than that in an identical single-stage bed.
- Total ΔP over the three-stage fluidized bed was less than that of an identical single-stage bed.
