Problem 2 A pollutant in a waste gas has a mol fraction of 0.03 The gas stream will be sent to a scrubber consisting of a simple absorber with 3 stages. The scrubbing liquid is free of pollutant and is fed to the scrubber at a rate such that G/L = 0.2 The equilibrium ratio for the pollutant is 0.7 a) (20 points) Write down the system of linear equations for the liquid mol fraction profile in the absorber. b) (20 points) Use your calculator to solve the system of equations from part a) c) (20 points) Calculate the mol fraction of pollutant in the gas stream leaving the absorber
