We want to separate a mixture of 25% mole of chloroform (1) and 75% mole of ethanol (2) at 55 °C. If you only know that the azeotrope of this mixture is x1 = y1 = 0.84 and 101.3 kPa at 55 °C, determine the following using the 1-parameter Margules activity coefficient equation. a. Sketch a diagram of all knowns and unknowns for the mixture above if you want to separate it in a flash drum at 65 kPa and 55 °C. b. Will the mixture flash at 65 kPa and 55 °C? You need to demonstrate this with calculations using the data above and properties of pure components in the Appendix of your textbook or other reliable databases. c. If the mixture will flash, find the flowrate and composition of the stream(s) leaving the flash separation unit.
