Prerequisite: CPE221 Engineering Thermodynamics & CPE211 Material & Energy Balances

Textbook: Chemical, Biochemical, and Engineering Thermodynamics 4th ed. by Stanley I. Sandler will be used as the main textbook for this course. One may wish to reference other texts for further discussion, e.g. Molecular Thermodynamics of Fluid-Phase Equilibria, 3rd Edition by J. M. Prausnitz, R.N. Lichtenthaler, E. Gomes de Azevedo Introduction to Chemical and Engineering Thermodynamics, by Smith and van Ness; Thermodynamics by O’Connell; etc. Supplementary material will be handed out as needed. A course reserve list is found in the Engineering Library.

Website: A very useful website has been established for the course which will contain lecture notes, homework problems and solutions, grades, announcements, and other useful information. Please check the site regularly. https://cpecourses.engr.ku.edu/CPE512_F09/

Coursework: Reading assignments will be given weekly. Homework will be assigned most weeks; depending on the total number of assignments, the lowest grade will be omitted. All assigned work is due at the beginning of class (within 5 minutes of the clock). Any work received late (>11:05am) but on the assigned day (before 5pm) will be assessed a late penalty of 15%; the following day 45% penalty; after 24 hrs, will Not be accepted. Solutions to all assignments will be available on the bulletin board outside LEA 4141C when homework is returned for approximately 2 weeks. Three exams will be given, tentatively scheduled for September 23th and November 4 th and the last day of classes (December 9th).

Grading: The grading scale for this course will be:Quizzes and Class Participation 7%Exam I: 18%Exam II: 18%Exam III: 18%Homework: 18%Final Exam 21%

The final grade will be determined by the gross score adjusted by the distribution of scores within the class.

“Re-grading”: If you believe that there is an error in the grading of a particular problem or assignment after you thoroughly examine the solutions, then re-grade requests must be made in writing within 2 weeks from the return of the assignment. The request must include a logical and step-by-step comparison of your method to the posted solutions and how your solution is equal to or better than the solutions and clearly demonstrate to the average chemical engineer that you both understand the concepts and have clearly communicated this.

Notes: Notes in .pdf form will be uploaded to the website before class. These notes will contain purposeful omissions to help the student to focus in class. These notes are given with the understanding that any errors found within will be reported immediately. The publication of these notes may be discontinued if student class preparedness is found to be declining. Your own personal notes should be taken in addition to those provided, since these are just a subset of what is orally presented.

Office Hours: The purpose of office hours is to allow students the ability to ask more and detailed questions about Phase Equilibrium Thermodynamics. Their primary role is to facilitate learning the material, not rendering answers to homework problems, checking mathematics, etc, etc. Expect to have the professor or TA to ask actual or rhetorical questions of the student to lead the student to better understanding. If you wish to meet outside of office hours, please submit your request and availability by email at least 24 hours before a potential meeting.

Email Policy: You are encouraged to ask me or the TA questions about material that you are having a difficult time understanding. While questions are best handled in person during office hours. However, if you need to ask a question by email beforehand, please allow at least 24+ hours for a response. Questions pertaining to homework must be sent before 3pm on the day prior to the due date for a potential chance of being answered.

Special Circumstances: If you are sick, have an emergency with family or loved-one, or have a religious holiday which requires you to miss a due date or examination, please contact me as soon as possible and well before the date of the absence. Alternative arrangements may be arranged. The staff of Services for Students with Disabilities (SSD), 135 Strong Hall, 785-864-2620 (v/tty), coordinates accommodations and services for KU courses. If you have a disability for which you may request accommodation in KU classes and have not contacted them, please do so as soon as possible. Please also see me privately in regard to this course.

Academic Misconduct and Ethics: Article II, Section 6 of the Rules and Regulations of the University Senate describes academic misconduct and the sanctions that may be imposed. For the purposes of this course, academic misconduct includes giving or receiving unauthorized aid on exams, homework or design projects. Copying the work of another or commissioning

2

authorship by another will be treated as academic misconduct. This includes copying from another student’s work, as well as copying sections of text from the internet without referencing the author. Academic misconduct shall be penalized by the assignment of a grade of zero for the work in question. A second offense shall result in an “F” grade for the course. In addition, the student will pledge not to use the information in this course for any illegal endeavor both nationally and internationally at anytime. Recording of lectures, class discussion, office hours, personal conversation, etc. is not permitted in any manner unless prior permission is granted in writing by the instructor. The regulation of class content, class schedule and student class behavior rests solely with the instructor.

All individual assignments turned in must be your own work. You are encouraged to work and learn from each other. However, copying of other students’ work (in any part large or small), and turning it in as your own is not permitted.

Possessing, and/or using the unpublished copyrighted textbook homework solutions (or copies thereof) either directly or from copies of homework of another student who used the solutions will result in an “F” for the course and does not fall under the “1 st and 2nd” offense policy stated above.

All homework must be done on engineering calculation paper. Use one side of each sheet; number pages; and write your name on each page. Box your answers. Graphs may be pasted onto the page or attached in another numbered page. Neatness counts. Unreadable homework will not be graded.

Class Etiquette: Address/treat fellow students and professor with respect. Cell phones must be turned off during class and discussion session. During lectures, Please do not: talk, use cell phones/text messaging; no laptops/wireless

(unless by written permission); read newspapers, work on other courses, etc.

Course Objectives

Students will: Understand measured, fundamental and derived thermodynamic properties Understand and use fundamental thermodynamic relationships to calculate properties Derive the fundamental connection between the Laws of Thermodynamics and phase

equilibria and stability. Use equations of state with appropriate software to calculate thermodynamic properties Understand the criteria for equilibrium between two phases Calculate fugacity for a component in a phase using a) equation of state and b) ideal

mixture reference states. Be able to interpret VLE, VLLE and SLE phase diagrams Understand the role of pure component saturation pressure and excess Gibbs energy

(activity coefficients) in determining the shape of VLE and VLLE phase diagrams. Be able to write the system of equilibrium constraints and material and energy balances

for a VLE or VLLE flash calculation, and understand the role of specifications in the calculation.

Using appropriate software, be able to solve and interpret the results of a VLE or VLLE flash calculation.

Using appropriate software and measured VLE of LLE data, be able to regress binary interaction parameters for an excess Gibbs energy model and/or Equations of State and

3

interpret the regression results in terms of a) quality of the data, and b) suitability of the excess Gibbs (activity coefficient) model.

Function affectively in a group situations to solve problems Classify problems into the equilibria sub-categories and select and justify models for each

situation. Design separation methods and conditions, based upon the phase equilibria Understand the criteria for chemical equilibrium for reacting systems.
