Question:

In the manufacture of methyl ethyl ketone (MEK). The product MEK is extracted from a solution in water using 1,1,2 trichloroethane as the solvent.

For a feed rate 2000 kg/h of solution, composition 30 per cent w/w MEK, determine the number of stages required to recover 95 per cent of the dissolved MEK; using 700 kg/h TCE, with counter-current flow.

Tie-line data for the system MEK–water–TCE percentages w/w, from Newman et al. (1949).

water-rich phase MEK 18.15 12.78 9.23 6.00 2.83 1.02 TCE 0.11 0.16 0.23 0.30 0.37 0.41 solvent-rich phase MEK
