In a simple implementation of that emission-control strategy, a gas mixture containing 45 mole% SO2 and the balance air (an SO2 concentration much higher than values normally encountered in power-plant emissions) flowing at a rate of 100 lb-mole/h is contacted with liquid water in a continuous absorber. The liquid leaving the absorber is analyzed and found to contain 2.00 g of SO2 per 100 g of H2O. Assuming that the gas and liquid streams leaving the absorber are in equilibrium at 30°C and 1 atm, calculate the fraction of the entering SO2 absorbed in the water and the required water feed rate.
