A gas stream is $90$mol$\%N_2$ and $10$mol$\%C{O}_2.$ We wish to absorb $C{O}_2$ into water. The inlet water

is pure and is at $5C.$ Operation is isothermal and is at $10$atm. If the liquid flow rate is $1\mathrm{.}5$ times

the minimum liquid flow rate, how many equilibrium stages are required to absorb $92\%$ of the

$C{O}_2?$ Choose a basis of $1mo\frac{l}{h}$ of entering gas.

Henry's law constant for $C{O}_2$ dissolution in water at $5C$ is $876at\frac{m}{m}$ole frac. i$.$e$.$

$P_{\text{t}\text{o}\text{t}}y=Hx$

Use this relation, to determine $K.$
