8. A pulp and paper mill is emitted ammonia gas (NH3) as a by-product to environment. To control the emission, the mill is using an absorption system for scrubbing NH3 from air with water. The water rate is 140kgmin1 and the gas rate is 115kgmin1 at 22 degree C and 1atm. The air to be scrubbed has 1.5% (mass basis) NH3 and is to be vented with 95% of the ammonia removed. (Table Q8: Equilibrium data for the ammonia air system). Table Q8 Equilibrium data for the ammonia air system a) Plot the equilibrium data in mole fraction units. KKKS6243 3 b) Perform the material balance and plot the operating line on the equilibrium plot. (12 marks) c) If the temperature increases, what would happen to the amount of NH3 absorption?
