Problem 1. In class, we discussed a classic real-world example of multi-stage flash for removing water (component 2) from ethylene glycol (component 1). The multi-stage flash system has three flash drums connected in series in the following configuration: V. Y.1 F.25 V2.91.2 V3. Vis 12,812 L3, X, 3 All flash drums are operated at 0.3 atm. The saturated liquid feed (F), which contains 40 mol% water, enters the first flash drum ar 1000 kmol/hr and is at 0.3 atm. Suppose 1/3 of the feed is vaporized in the first flash drum, 2/3 of the feed to the second flash drum is vaporized in the second flash drum, and finally, 1/2 of the feed to the third drum is vaporized. (a) Use Aspen Properties to generate the required x-y diagrams and use the graphical method to determine the mole fraction of water in all liquid and vapor product streams. Also, determine the operating temperature for all three flash drums. In your x-y diagrams, label all intermediate stream compositions and slopes of mass balance lines. (b) Directly simulate this multi-stage flash process in Aspen HYSYS and determine the mole fraction of water in all liquid and vapor product streams, as well as the operating temperature for all three flash drums. Then, compare your results with what you get from Part (a). Attach a screenshot of your converged Aspen HYSYS flowsheet as well as a screenshot of compositions of all liquid and vapor streams (which can be found under the worksheet" tab when doubling clicking the separator). Hint: In Aspen Properties, ethylene glycol can be found by directly searching its name. In Aspen HYSYS, ethylene glycol is named simply as "EGlycol". When setting up your Aspen Properties or Aspen HYSYS files, choose NRTL activity coefficient model as the thermodynamic package
