Argon and methane are absorbed from nitrogen into liquid ammonia at 252.3 k and 175.0 atm. feed rate of gas is 100 kmol/h. feed gas contains 0.020 mol% ar and 0.130 mol% methane. outlet gas contains 0.0008 mol% methane. the entering liquid ammonia is pure. the system operates with l/v = 26.0. assume l and v flow rates are constant. equilibrium data for methane is, partial pressure methane = 3600 atm and the partial pressure for argon = 7700 atm. a. find the outlet mole fraction of methane in the liquid b. find the number of equilibrium stages required. c. find the outlet mole fraction of argon in the gas.
