At 45 o C, 1,000 kg/h of a mixture of 0.80 mass fraction docosane and 0.20 mass

Question:

At 45^oC, 1,000 kg/h of a mixture of 0.80 mass fraction docosane and 0.20 mass fraction diphenylhexane is to be extracted with pure furfural to remove some of the diphenylhexane from the feed. Phase-equilibrium data for this ternary system are given in Exercise 8.15. Determine:

(a) The composition and flow rate of the extract and raffinate from a single equilibrium stage for solvent flow rates of 100, 1000, and 10000 kg/h.

(b) The minimum solvent flow rate to form two liquid phases.

(d) The composition and flow rate of the extract and raffinate if a solvent flow rate of 2000 kg/h and two equilibrium stages are used in a countercurrent flow system.
