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 $20mo{l}_{\%}S{O}_2$ and that leaving the column should have $2$mol$\%S{O}_2$ it a total pressure of $1013$kPa. The inert air flow rate is $150kg$ air $\frac{?}{h},m2$ and the entering water flow rate is $6000kg$ water $\frac{?}{h},m2.$

$($a$)$ Draw the schematic diagran of the process. $($Assume the top tray is Tray $1).$

$($b$)$ The equilibrium data is given in the Table below. Convert the data into the solute free basis $(x$ and $Y).$

$($c$)$ What is the minimum flowrate $L_{\text{m}\text{i}\text{n}\text{i}\text{n}}?$

$($d$)$ Plot the operating line and the equilibrium line based on the solute free basis.

$($e$)$ Determine the total number of tray required.

$($f$)$ Use the Kremser method to calculate the number of tray and compare tha$-$sasults.
