Solve the following absorption process. $(20$ marks$)$

A tray tower is to be designed to absorb $S{O}_2$ from an air stream by using fresh water at $293K.$ The entering gas contains $10$mol$\%S{O}_2$ and that leaving the column should have $1\mathrm{.}2$mol$\%S{O}_2$ at a total pressure of $101\mathrm{.}3$ kPa.

The gas flowrate entering the column is $10$kgmo$\frac{l}{h}$ consisting of air with $S{O}_2$ at $10$mol$\%.$

It is desired to use the water flowrate at $2L_{\text{m}\text{i}\text{n}}$ where $L_{\text{m}\text{i}\text{n}}$ is the minimum solvent $($water$)$ flowrate. The equilibrium data can be approximated by the following equation.

$y=29\mathrm{.}3x$

The graph below shows the equilibrium plot.

Assuming that this process can be considered dilute$*,$ determine the following:

a$)$ Determine the minimum water flowrate $L_{\text{m}\text{i}\text{n}}$ and the actual water flowrate, $L$ to be used.

b$)$ Determine the total number of tray required. You can use the graph below or you can draw on your own.

$(*$Hint: Since it can be considered dilute, you can directly use L and V$,$ no need to convert to $L^{\text{'}}$ or $V^{\text{'}}).$
