You are asked to remove 90% of the sulfur dioxide in a stream of air, and sulfur dioxide that flows at the rate of 85 m³ per minute and contains 3% sulfur dioxide. The sulfur dioxide is to be removed by a stream of water. The entering water contains no sulfur dioxide. The temperature is 290 Kand the pressure on the process is 1 atm. Calculate (a). the kilograms of water per minute needed to remove the sulfur dioxide assuming that the exit water is in equilibrium with the entering gas and (b) the ratio of the water stream to the gas stream. The Henry's law constant for sulfur dioxide at 290 K is 43 atm/mole fraction.
