Question
The following results were obtained for Tray n from a rate-basedcalculation of a ternary distillation at 14.7 psia, involving acetone (1), methanol (2), and water (3) in a 5.5-ft-diameter column using sieve trays with a 2-inch-high weir. Vapor and liquid phases are assumed to be completely mixed.The computed products of the gas-phase, binary mass-transfer coefficients
and interfacial area, using the Chan–Fair correlation of §6.6,are as follows in lbmol/:
k12 =k21=1, 955; k13 =k31 =2,407; k23=k32 = 2,797
(a) Compute the molar diffusion rates. (b) Compute the masstransfer
rates. (c) Calculate the Murphree vapor-tray efficiencies.
