A liquid feed stream of 1500 kg/h consisting of 35 wt. % acetonitrile (1) and 65% water (2) is to
be extracted using isobutyl methyl ketone (3) as the solvent. If the flow rate of the solvent is 500
kg/h, determine the flow rates and compositions of the exit streams using the phase diagram
(mass fractions) below. The overall process takes place at a constant temperature of 303 K.
