Agas stream contains 10% co2 by volume and 90 % n2. 95% of co2 is to be removed by absorption into pure water. the tray absorption column is operated at 10 atm and 5 °c. estimate the number of the equilibrium stages required if the liquid rate of 1.5 times the minimum liquid henry's law constant for co2 in water at 5 °c is 876 atm/mole fraction rate is used
