In an ammonia plant we wish to absorb traces of argon and methane from a nitrogen stream using liquid ammonia. operation is at 240 k and 180 atm pressure. the feed flow rate of gas is 100 kmoles/h. the gas contains 0.00022 mole fraction argon and 0.0015 mole fraction methane. we desire to remove 97% of the methane. the entering liquid ammonia is pure. operate with l/v 1.3(ln)min. assume the total gas and liquid rates are constant. the equilibrium data at 240 k are: methane: pmethane (atm) 3400 xmethne argon ppon (atm)7500 xaron (a) find the outlet methane mole fraction in the gas 3 marks] 6 marks) 4 marks] (b) find (l/v)min and the actual lv (c) find the outlet methane mole fraction in the liquid. (d) find the number of equilibrium stages required [5 marks] (e) find the outlet argon mole fractions in the liquid and the gas, and the % recovery of argon in the liquid.

4. a gas containing equal parts methane, ethane and ammonia flows at a constant rate through a laboratory water- based absorption unit, which absorbs 96% of the ammonia and retains all the water. no methane or ethane is absorbed and no water evaporates. initially there was 5 l of water in the absorber, at the end of 4 hours the liquid mass is 5.25 kg. calculate the molar flowrate of the gas stream into the absorber, and the mole fraction of ammonia in the exit gas stream
