= A chemical plant produces 115.0 m/h of waste gas (p 0.0407 mol/L) initially having a mole fraction of 0.160 NH, and wishes to remove 90.0% of the initial amount of NH3. The maximum concentration of ammonia in water at this temperature is 0.5000 mol NHz/mol water. Neglect the absorption of other waste gas components into the water and the evaporation of water into the waste gas stream, and assume that the minimum flow rate of water is used. The flow diagram for this process is given. The component of waste gas that is not NH, is abbreviated as A. n3 mol/h waste gas (unknown) Y3 mol NH,/mol waste gas (unknown) y4 mol A/mol waste gas (unknown) V2 L/h water (unknown) n2 mol/h water (unknown) Scrubber N4 mol/h effluent liquid (unknown) X mol NHz/mol effluent liquid (unknown) x2 mol water/mol effluent liquid (unknown) 115.0 m3/h waste gas nj mol/h waste gas (unknown) y = 0.160 mol NHZ/mol waste gas y2 mol A/mol waste gas (unknown) What is the molar flow rate, ni, of the unscrubbed waste gas stream? ni = mol unscrubbed waste gas h What is the mole fraction of non-ammonia components of the unscrubbed waste gas (referred to as A), y2? Y2 = mol A mol unscrubbed waste gas What is the mole fraction of NH3, X1, in the effluent stream? x1 = mol NHZ mol effluent What is the mole fraction of water, X2, in the effluent stream?
