QUESTION $4$

A gas mixture containing $85\mathrm{.}0$mole$\%N_2$ and the balance $-$hexane flows through a pipe at a rate of a hundred cubic meters per hour. The pressure is $2\mathrm{.}00$atm absolute and the temperature is $100C.$

What is the molar flow rate of the gas in kmo$\frac{l}{h}?($Answer: $6\mathrm{.}53$kmo$\frac{l}{h})$

Is the gas saturated? If not, to what temperature $(C)$ would it have to be cooled at constant pressure in order to begin condensing hexane? $($Answer: $34\mathrm{.}8C$

To what temperature $(C)$ would the gas have to be cooled at constant pressure in order to condense $80\%$ of the hexane? $($Include a process flow diagram in your solution and use the flowrate obtained in $2).($Answer: $2\mathrm{.}52C$
