A feed of 110 lbmol/h includes 5, 3, and 2 lbmol/h, respectively, of formic acid, acetic acid, and propionic acid in water. If the acids are extracted in a single equilibrium stage with 100 lbmol/h of ethyl acetate (EA), calculate with a simulation computer program using the UNIFAC method, flow rates and molar compositions of the resulting two liquid phases. What is the order of selectivity of EA for the three organic acids?
