Question $3$

The feed stock to a distillation column consist of the following mole fractions:

$18$

$25\%$ Propane $(C_3)$

$40\%$ Isobutane $(i-C_4)$

$10\%$ Isopentane $(i-C_5)$

$25\%$ Normal pentane $(C_5)$

This feed $($Stream $1),100$kmo$\frac{l}{h}$ is separated into two fractions $-$ a distillate $($Stream $2)$ and a bottom $($Stream $3).$ The distillate is to contain all the propane fed to the unit and $70\%$ of the iso$-$pentane fed to the unit and is to consist of $30\%$ isobutene. The bottom stream is to contain all the normal pentane fed to the unit.
