A stream of mixture containing 50 wt% liquid A, 30 wt% liquid B and 20 wt% liquid C is fed through a series of distillation columns. The first column is designed to evaporate (distillate) liquid A and B from liquid C. This column is able to separate all of liquid C from the main feed as a bottom product of the column. In addition, the bottom product stream contains 5 wt% liquid A and 5 wt% liquid B. Meanwhile, the vapor mixture of A and B leaves the top of the first column and is completely condensed before entering the second column. The bottom product of the second column contains 90 wt% liquid B while only pure vapor of A appears at the top of the column which is later condensed (liquid) as the final product. a) Draw and label a flowchart of the process b) If the manufacturer want to produce 1000 kg of liquid A per day, how many kg per day of the feed mixture stream are required to feed to the first distillation column? c) What is the weight percentage of liquid A in the feed to the second distillation column?

A stream of mixture containing 50 wt% liquid A, 30 wt% liquid B and 20 wt% liquid
C is fed through a series of distillation columns. The first column is designed to
evaporate (distillate) liquid A and B from liquid C. This column is able to separate
all of liquid C from the main feed as a bottom product of the column. In addition,
the bottom product stream contains 5 wt% liquid A and 5 wt% liquid B. Meanwhile,
the vapor mixture of A and B leaves the top of the first column and is completely
condensed before entering the second column. The bottom product of the second
column contains 90 wt% liquid B while only pure vapor of A appears at the top of
the column which is later condensed (liquid) as the final product.
a) Draw and label a flowchart of the process
b) If the manufacturer want to produce 1000 kg of liquid A per day, how many
kg per day of the feed mixture stream are required to feed to the first
distillation column?
c) What is the weight percentage of liquid A in the feed to the second
distillation column?
