Example $10-1.$ Production of Chlorine $($Deacon Process$)$

In the Deacon process for the manufacture of chlorine, $HCl$ and $O_2$ react to form $C{l}_2$ and $H_{2}O.$

Sufficient air $(21$mole$\%O_2,79\%N_2)$ is fed to provide $35\%$ excess oxygen and the fractional conversion of $HCl$ is $85\%.$

Determine the amount of air required per mole of $HCl$ fed into the process.Calculate the mole fractions of the product stream components using:

a$.$ molecular species balances

b$.$ atomic species balances

c$.$ extent of reaction
