Problem $2[60\%]$

Gas of the following composition is to be processed by refrigeration to $-20C$ :

$\backslash$table$[[$Component$,$Mol $\%],[$Nitrogen$,1\mathrm{.}0],[C{O}_2,3],[H_{2}S,8\mathrm{.}0],[$Methane$,72],[$Ethane$,11\mathrm{.}0],[$Propane$,5\mathrm{.}0]]$

a$.$ Calculate the equilibrium water content of the gas at the delivery condition of $30C$ and $8\mathrm{.}6$ MPa.

b$.$ What is the temperature limit for hydrate formation from this gas stream at $8\mathrm{.}6$MPa $?$

c$.$ How much ethylene glycol solution $(80\%$ in water$)$ would be required to protect the equipment from hydrate formation, per standard $m^3$ of gas processed?
