The feed stream to a distillation column contains 30 % propane, 50 % butane and 20 % pentane. The overhead tops product concentrate contains 80 % propane and 15 % butane, and the bottoms product contains 2 % propane. Determine the following: a) The yield (%) of overhead product per unit of feed. b) The concentration of butane and pentane in the bottoms product stream. c) The recovery (%) of propane from the feed into the overhead product (i.e. what fraction of propane in the feed stream exits in the overhead product). d) The recovery (%) of pentane from the feed into the bottoms product

Question
The feed stream to a distillation column contains 30 % propane, 50 % butane and 20 % pentane. The
overhead tops product concentrate contains 80 % propane and 15 % butane, and the bottoms
product contains 2 % propane. Determine the following:
a) The yield (%) of overhead product per unit of feed.
b) The concentration of butane and pentane in the bottoms product stream.
c) The recovery (%) of propane from the feed into the overhead product (i.e. what fraction of
propane in the feed stream exits in the overhead product).
d) The recovery (%) of pentane from the feed into the bottoms product.
