Question:

One hundred kilogram-moles per hour of an equimolar mixture of benzene (B), toluene (T), n-hexane (C6), and n-heptane (C7) is to be extracted at 150°C by 300 kmol/h of diethylene glycol (DEG) in a countercurrent, liquid-liquid extractor having five equilibrium stages. Estimate the flow rates and compositions of the extract and raffinate streams by the group method. In mole-fraction units, the coefficients for the hydrocarbon can be assumed essentially constant at the following values: For diethylene glycol, assume KD = 30.
