Question 3(50 points). Forty-five kg of a solution of 30wt% ethylene glycol in water is to be extracted with furfural. Using Figure 3, calculate the: (a) minimum kg of solvent ( 10 points) (b) maximum kg of solvent ( 10 points) (c) kg of extract and raffinate for 45kg solvent, and the compositions of each stream (20 points) (d) maximum purity of glycol in the extract and the maximum purity of water in the raffinate for one stage (10 points) Furfu (S) Figure 3. Equilateral triangular diagram for glycol-water-furfural system Note: - The minimum amount of solvent corresponds to the maximum solubility of the solvent in the feed (maximum purity of solute in the extract can be achieved). - The maximum amount of solvent corresponds to maximum solubility of the feed in the solvent (maximum purity of water can be reached in the raffinate)
