chemical plant produces an ammonia-rich waste gas that cannot be released as is into the environment. One method to reduce he ammonia concentration in the waste gas is to bubble the waste gas though a liquid solvent. Components of the gas that are aighly soluble, like ammonia, will dissolve into the liquid phase. Water is an appropriate liquid solvent for this process. The chemical plant produces 120.0m3/h of waste gas (=0.0407mol/L) initially having a mole fraction of 0.100NH3 and wishes to remove 90.0% of the initial amount of NH3. The maximum concentration of ammonia in water at this temperature is into the waste gas stream. At what rate is NH3 being removed from the feed gas? rate of NH3 removal: What is the minimum flow rate of water (=0.990g/mL) required to scrub out 90.0% of the incoming NH3 ? minimum flow rate of water L/h What is the mole fraction of NH3 in the scrubbed waste gas stream? mole fraction
