4-22. A distillation column is used to separate a mixture of methanol, ethanol, and isopropyl alcohol. The feed stream, with a mass flow rate of 300 kg/hr, has the following composition: Component methanol Species mass density 3 395.5 kg/m 3 197.3 kg/m ethanol 13 196.5 kg/m isopropyl alcohol Separation of this mixture of alcohol takes place according to the following specifications: (a) 90% of the methanol in the feed leaves with the distillate stream (b) 5% of the ethanol in the feed leaves with the distillate stream (c) 3% of the isopropyl alcohol in the feed leaves with the distillate stream. Assuming that the volumes of the components are additive, compute the concentration and volumetric flow rates of the distillate and bottom streams

Transcribed Image Text:4-22. A distillation column is used to separate a mixture of methanol, ethanol, and isopropyl alcohol. The
feed stream, with a mass flow rate of 300 kg/hr, has the following composition:
Component
methanol
Species mass density
3
395.5 kg/m
3
197.3 kg/m
ethanol
13
196.5 kg/m
isopropyl alcohol
Separation of this mixture of alcohol takes place according to the following specifications:
(a) 90% of the methanol in the feed leaves with the distillate stream
(b) 5% of the ethanol in the feed leaves with the distillate stream
(c) 3% of the isopropyl alcohol in the feed leaves with the distillate stream.
Assuming that the volumes of the components are additive, compute the concentration and volumetric flow
rates of the distillate and bottom streams
