Answer to Question #261926 in Chemical Engineering for Leke

Question

the distillation column of an Acetaldehyde plant has the following process

conditions temperature, 60 0C; gas density,3220 g/cm3., liquid density,

0.74g/cm3., L/D =3; Bottom flow rate = 139 kg/hr; distillate flow rate=25kg/hr;

Liquid flow rate at top of the column =75 kg/hr; vapour rate at the top =

100kg/hr: Plate spacing of60 cm; maximum vapour density = 1.603 m/s;

assuming safe operating velocity as 60% of this value, determine (a) the column

cross-sectional area (b) diameter of the column.
