Consider the liquid-liquid phase diagram shown here for components A, B, and C. All axes are labeled in mass percent terms: 1. What are the compositions of the two phases resulting from a mixture of 65%A,11%B and 24% C? 2. If the flow rate of this mixture into the system is 1200lbs/h, what are the flow rates of the two product streams? 3. Consider a feed stream that consists of 1000lbs/hA and 350lbs/hB. If this feed is mixed with a solvent stream that consists of 90%C and 10%B, what is the highest concentration of B that can be achieved in the extract? What is the concentration of B in the raffinate under these conditions? 4. For the feed conditions described in part (3) and a solvent stream containing pure C, what is the lowest solvent flow rate that will result in two liquid phases
