The system may be assumed to meet the standard of 90% removal of the SO₂ released upon combustion.

a. Determine the flow rate (kg/min and kmol/min) of each component in the cleaned flue gas leaving the scrubber.

b. Determine the flow rate (kg/min) of slurry entering the scrubber.

c. Estimate the solid-to-liquid mass ratio in the slurry leaving the scrubber.

d. Estimate the feed rate (kg/min) of fresh ground limestone to the blending tank.

e. What are the flow rates (kg/min) of inerts, CaSO₃, CaCO₃, fly ash, and water in the wet solids removed from the filter? What fractions of the CaSO₃ and CaCO₃ are dissolved in the liquid portion of the wet solids?

f. Estimate the rate (kg/min, L/min) at which the filtrate is recycled to the blending tank. At what rate (kg/min, L/min) is makeup water added to the blending tank?
