Acetone is to be removed from air in an isothermal dilute absorber using pure water as solvent. The incoming air contains 5 mole% of acetone (yin = 0.05). The design equation to be used for obtaining the number of trays (N) of the absorber is: N + 2 = 6 log $$\left( {\frac{{{{\text{y}}_{{\text{in}}}}}}{{{{\text{y}}_{{\text{out}}}}}}} \right).$$
For 98% recovery of acetone, the number of trays required is/are
