Assignment:
It is desired to remove 90% of the sulfur dioxide in a flue gas stream at 298 K and 1 atm by countercurrent absorption with pure water at the same temperature, using a packed tower that is 0.7 m in diameter. The tower is packed with 35-mm plastic NORPAC rings. The average gas-pressure drop is 200 Pdm. Equilibrium is described by Henry’s law with yi = 8.4~~. If the liquid flow is adjusted so that the driving force (y - y*) is constant, calculate the height of the packed section. Flue gases usually contain less than 1 mol% of SO,, an air pollutant regulated by law. Assume that the properties of the liquid are similar to those of pure water and that the properties of the flue gases are similar to those of air.
Provide complete and step by step solution for the question and show calculations and use formulas.
