Problem.

The largest chemical plant owned by your employer produces $10,000$kmo$\frac{l}{s}$ of a toxic gas which has a $N_{x}O$ content of $9\mathrm{.}5$ mol$\%.$ It is desired to remove $83\%$ of its nitrous oxide content by contact with pure water and you have been tasked with the preliminary equipment design. According to your experienced supervisor, the design water flow rate should be $95\%$ higher than the minimum. The equilibrium data is also available $($see the provided plots $(x-y$ and $x-Y).$

$1.$ Calculate Y$1,$y$2,$Y$2,$X$2,$V$2$ and Vs

$2.$ Minimum Ls

$3.$ Actual water flow rate Ls$,$ L$2$

$4.$ Calculate the NxO concentration in water leaving the absorber $($x$1,$X$1)$ and L$1$
