Carbon tetrachloride $(CC{l}_4)$ will be stripped from water using pure air at $25C$ and $745mmHg$

pressure in a countercurrent packed stripping column. The inlet water is saturated with carbon

tetrachloride and the exit water should contain $1ppm($mol$).$ See Table $12-2$ of Wankat for

equilibrium and solubility data. The liquid flowrate is $500$kmo$\frac{l}{h},$ and the tower will operate at

at $(\frac{L}{G})=0\mathrm{.}8(\frac{L}{G}{)}_{\text{m}\text{a}\text{x}}.$ The tower diameter is $1m.H_{OL}$ is estimated to be $0\mathrm{.}59m.$

a$.$ What is the height of packing required?

b$.$ What is the overall liquid phase mass transfer coefficient, $K_{x}a?$
