SCHOOL OF CHEMICAL ENGINEERING CEIC3001 Advanced Thermodynamics and Separation Tutorial 6 Question 1 A mixture containing 65 mol% benzene (1) and 35 mol% toluene (2) is to be separated by distillation. The feed enters the distillation column as a saturated liquid. The specification for the distillate is 95 mol% benzene while the bottom product must contain a minimum of 95 mol% toluene. The column is operating at a pressure of 1 atm. Using the y - x diagram at the back of this sheet: a) Determine the minimum number of stages required to achieve the given

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
