Waste gas containing ammonia and sulfur dioxide is treated by water absorption in a single-stage treatment process. The waste gas enters the process at 1 atm pressure and 30°C. The air contains 5.0% v/v ammonia and 7% v/v sulfur dioxide and must leave the with 500,000 ppb ammonia and 400,000 ppb sulfur dioxide. Air, ammonia, and sulfur dioxide can be taken as ideals gases. There is no water and air carryovers in the treated gas and wastewater streams, respectively. If the flow rate of the waste gas to the process is 500 m3/s, calculate the flow- rate of water to the column if the wastewater must contain less than 1% w/w ammonia and less than 2% w/w sulfur dioxide.
