For counter-current absorption in a packed column, it was found that the liquid and the gas flowrates are equal. The equilibrium relation is given by Y*=X, where Y* is the mole fraction of solute in the gas phase and X is the mole fraction of solute in the liquid phase. Assuming dilute relations, if the gas phase driving force (Y-Y*) at the top of the column 0,0058 and gas mole ratio has to be reduced from 0.01 to 0.0098, then the number of gas phase transfer units required is (up to two decimal place).
