A feed of 100 kg/min of 1.2 wt% mixture of acetic acid in water is to be extracted with 1-butanol at 1 atm and 26.7 °C The desired outlet concentration in the exiting stream is 0.1 wt% of acetic acid .The solvent of pure 1-butanol is fed counter-currently to the feed with the flow rate of 75 kg/min .Determine the composition of the exiting 1-butanol phase (i.e. the extract phase) Also find the number of equilibrium contacts (stages) needed.
