Answer the following question:

In hydrocarbon recovery process, a train of distillation columns is used. Each column is designed to make a split between two adjacent key components in the feed, whose components are ordered in decreasing volatility. If the components molar flow rate of the top product from the first and second distillation columns are given in the table below.

Calculate the split fraction and split ratio of the components and determine the key splits in each column.

$2-$ Calculate the split power for the key split components in each column.

$3-$ Calculate product purities

$4-$ Based on the following entry, write in $/$ draw possible separation sequences

Hydrocarbon feed : propane $(C_3),$ isobutane $(i{C}_4),n-$butane $(n{C}_4).$ isopentane $(i{C}_5),n-$pentane $(n{C}_5)$

$=>$ Products : $C_3,i{C}_4,n{C}_4,i{C}_5+n{C}_5$
