100 mol/h of mixture of A (20 mol%) and C (80 mol%) at 40C is to be separated into 98 mol% pure A and 98 mol% pure C. The T-x-y diagram of A-C mixture is shown below. Use minimum number of flash drums and liquid-liquid gravity separators. a) Draw a flow diagram with all the flash drums, heaters, condensers, and liquid-liquid separators and the recycle. b) Specify the temperature of the units and composition of the streams. c) Write a material balance for all the units and calculate all unknown flow rates.
