Calculate the composition of the equilibrium extract and raffinate phases produced

when a $35\%$ by weight ethylene glycol $($B$)-65\%$ water $($A$)$ solution is contacted

with the twice and half times amount of solvent containing $96\%$ furfural and $4\%$

ethylene glycol by weight at $25C$ and $101$kPa.
