To separate propylene from trans-2-butene in a distillation column, the feed stream is available as saturated liquid at 15 bar, and has the following compositions. propylene 45 mol/s, trans-2-butene 10 mol/s, cis-2-butene 15 mol/s, 1-butene 6 mol/s, ethylene 5 mol/s, propane 4 mol/s. It is desired to recover 99.5% of the propylene in the distillate and 99% of the trans-2-butene in the bottom stream. 1- Determine the temperature of the feed stream and the minimum number of stages. 2- Determine the mole fraction composition of the distillate and the bottoms.

Homework
To separate propylene from trans-2-butene in a distillation column, the
feed stream is available as saturated liquid at 15 bar, and has the following
compositions.
propylene 45 mol/s, trans-2-butene 10 mol/s, cis-2-butene 15 mol/s,
1-butene 6 mol/s, ethylene 5 mol/s, propane 4 mol/s.
It is desired to recover 99.5% of the propylene in the distillate and 99% of the
trans-2-butene in the bottom stream.
1- Determine the temperature of the feed stream and the minimum number of
stages.
2- Determine the mole fraction composition of the distillate and the bottoms.
