Question
Transcribed Image Text:D2. We are separating a mixture of propylene, propane, and
isobutane in a distillation column with a partial condenser
and a partial reboiler at a pressure of 15.0 bar. We desire a
0.999 fractional recovery of propylene in the distillate, at least
a 0.950 fractional recovery of propane in the bottoms, and at
least a 0.9999 fractional recovery of isobutane in the bottoms.
How many stages are required at total reflux?
Data: At 34°C, K Propylene 1.00, K propane
isobutane = 0.42.
At 40°C, K propylene
isobutane = 0.46.
=
=
= 0.89, K
