Mass Transport Operations

Question $1$:

A tray tower is to be used to remove $94\%$ of the ammonia from an entering air stream containing $6$ mol$\%$ ammonia at $293K$ and $1\mathrm{.}01325{10}^{5}Pa.$ The inert air flow rate is $188kg$ inert air $\frac{?}{h}*m^2.$

Determine the minimum solvent flow $($i$.$e$.$ pure water$)$ rate for the required separation, $L_{\text{m}\text{i}\text{n}}.$

Using $L=1\mathrm{.}4L_{\text{m}\text{i}\text{n}},$ determine the required solvent flowrate $kgmol{H}_2\frac{O}{h}*m^2.$

Determine the compositions of the solvent and the gas phase leaving the absorber$.$

Calculate the number of theoretical trays needed using the graphical method

Compare your results using the analytical Kremer method

Given below is the equilibrium data from Appendix A$\mathrm{.}3.$ For the dilute end of the tower, plot an expanded diagram to step off the number of trays more accurately.
