Questions and Answers > n an ammonia plant, we wish to absorb traces of argon and methane from a nitrogen stream using liquidammonia.Operation is at 253.2 K and 175 atm pressure.The feed flow rate of gas is 100 kmol/h.The gascontains 0.00024 mole frac argon and 0.00129 mole frac methane.We desire to remove 95 % of the methane.The entering liquid ammonia is pure.Operate with L/V = 1.4 (L/V)min.The equilibrium data at 253.2 K are:Methane: partial pressure of methane in atm = 3600 (methane mole frac in liquid) Argon: partial pressure of argon in atm = 7700 (argon mole frac in liquid) (a)Find outlet methane mole frac in the gas. (b)Find (L/V)minand actual L/V. (c)Find outlet methane mole frac in the liquid. d)Find the number of equilibrium stages required. (e)Find the outlet argon mole fracs in the liquid and the gas, and the % recovery of argon in the liquid.
