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 (yin
/yout
).For 98% recovery of
acetone, the number of trays required is/are:
(A) 4
(B) 8
(C) 9
(D) 10
