A vapor mixture of $100mo\frac{l}{s}$ comprising $55$mol$\%$ benzene and $45$mol$\%$ toluene is sent to a

partial condenser operating at $760mmHg\mathrm{.}75$mol$\%$ of the toluene in the feed is recovered in the

liquid product. Determine all unknown flow rates, compositions, and required heat removal.

a$.$ Draw a process flow diagram and do a degree of freedom analysis

b$.$ Write out equations used to solve and specifications used in Excel Solver to

calculate all unknown flow rates, compositions,

c$.$ Specify the temperature and pressure of the feed as $T_F=102C$ and $P_F=760mm$

$Hg.$ Choose the lowest enthalpy stream $($liquid product stream$)$ for a reference condition.

Calculate the required heat removal analytically by hand $($No Excel Solver$).$

d$.$ Create Enthalpy Table
