During an extraction process a water solution of acetic acid is contacted with the solvent hexanol. the water phase before the extraction has a total mass of 400 g and the mass fraction of acetic acid is xfeed = 0.115. after the extraction the mass fractions of acetic acid in the organic extract is xextract = 0.096 and in the water raffinate is xraffinate = 0.005. a) draw a process diagram for the extraction process incl. values of known quantities and symbols of unknowns. b) how many independent mass balances can be written for the process? c) how many unknowns are found? d) how many dof? e) calculate the mass of hexanol (in grams), which is needed for the extraction and the mass of the organic extract and the water raffinate. f) calculate the mass loss of acetic acid in the water phase and control that it is equivalent to the gain of acetic acid in the organic phase.
