Part I: Lab absorption

Please support your explanations with screenshots of the simulation whenever possible

In the technological hall, there is an absorption unit in a packed column filled with pall rings. The unit has two inlet streams: one gas stream consisting of $97$mol.$\%$ air and $3$mol.$\%$ acetone, and one

liquid stream consisting of pure water. The acetone and air is premixed before entering the unit. The acetone from the air is continuously absorbed with water at $15C$ and $1$atm. At the aforementioned

conditions, the following information is given:

The gas flow rate is $20\frac{f{t}^3}{\text{m}\text{i}\text{n}}.$

A $97\%$ of acetone recovery is desired.

The density of gas is assumed to $1\mathrm{.}259\frac{kg}{m^3}.$

There is no absorption of air and no stripping of water.

The cross$-$sectional area of the column is approximately $0\mathrm{.}0119m^2.$

The overall volumetric mass transfer coefficient in gas phase $K_{y}a=320\mathrm{.}36\frac{\text{k}\text{m}\text{o}\text{l}}{h*m^3}.$

The equilibrium relation is $y=1\mathrm{.}294x,$ where $y$ and $x$ are the mole fractions of acetone in the gas and liquid phases, respectively.

$1)$ Make a schematic drawing of the setup.

$2)$ Calculate the following variables:

The minimum liquid molar flow rate in $\frac{\text{k}\text{m}\text{o}\text{l}}{h}.$

The number of theoretical stages for a liquid molar flow ratio $1\mathrm{.}5$ times the minimum.

The number of overall gas transfer units $($NTU$).$

The overall height of the gas transfer unit $($HTU$)$ in meters.

The height of the column in meters

For the aforementioned calculation, please provide a clear list of symbols, any assumptions that you have made, and data you have cited from literature sources.$)$

$3)$ Quantitatively and qualitatively discuss how the height of the column varies as a function of the liquid$-$to$-$vapor molar flow rate ratio $($e$.$g$.,1\mathrm{.}0,1\mathrm{.}5,2,10),$ assuming that the gas flow rate and HTU

remain constant $($so constant recovery of acetone$).$

$4)$ Quantitatively and qualitatively discuss how the recovery of acetone is affected by the liquid$-$to$-$vapor molar flow rate ratio $($e$.$g$.,1\mathrm{.}0,1\mathrm{.}5,2,10),$ assuming that the number of theoretical stages

remains constant at $6\mathrm{.}42($i$.$e$.,$ constant column height$).$

$5)$ Compare the results from questions $3)$ and $4).$ What could you conclude from? What would you recommend to obtain a high recovery of acetone?
