A pure solvent (flow rate= 299.4 kg/h) is used to extract a solute from a feed (flow rate= 50.0 kg/h) that is 35% solute and 65% carrier. What are the compositions and flow rates of the extract (the solvent-rich phase leaving the stage) and of the raffinate (the effluent carrier phase from which solute was extracted) streams? The ternary phase diagram is shown below.
