It is estimated that 7.25 ideal stages are required for the absorption of a solute A from a gas stream (15 kmol/s) to a liquid stream (185 kmol/s) at room temperature and pressure (298 K and 1 atm). Under these conditions, the equilibrium line is y = 10 x. i) Calculate the liquid and gas solute-free flow rates (i.e. Ls and Gs) at a stage in which the composition of A in the liquid is 0.09. Assume equilibrium condition. ii) Calculate the absorption factor ( = Ls/aGs) a that stage. Note that you need to calculate the equilibrium term alpha at solute free base Y = ax. Calculate the real number of stages. Consider a tower with a diameter of 2 m and a Murphy efficiency (Eng) of 0.5. The overall efficiency can be calculated with: mG' In (1 + EMC 1 + Ema (MG" 1)] E. mG (MG) In which G' and L' are liquid and gas flow rate on basis of unit cross section area. iii)
