Syllabus
Prerequisites: Phase (vapor-liquid) equilibria; macroscopic material and energy balances; equipment for transport of fluids and for heat exchange.
Target skills and knowledge: The students will learn the principles of some fluid-phase separation operations, and some methodologies for the approximate design of the relevant equipment. At the end of the course, the student is expected to be able to:
• understand how vapor-liquid equilibria affect the possibility to separate a mixture into its components;
• understand the working principles of flash drums, distillation columns, absorption columns and stripping columns;
• understand the relationships between capital costs and operating costs in separation columns;
• approximately design flash drums, as well as tray and packed columns for distillation, absorption and stripping operations;
• evaluate the energy requirements of separation systems;
• use a process simulator for the study of elementary separation operations.
Examination methods: The exam includes two mandatory sequential activities: in-course homework activities and final written exam. Two homework activities are to be done individually, whereas the third one is a team activity to be completed in 24 hours. The homework contributes about 15% of the final grade; the remaining 85% is contributed by the final written exam. The written exam typically includes three questions on topics related to the entire course syllabus, and lasts about one hour; the use of lecture notes, textbooks or calculator is not permitted.
Assessment criteria: HOMEWORK
• correctness of the final solution
• clarity and synthesis in the presentation of the results
• appropriateness of use of technical terminology
WRITTEN EXAM
• knowledge and understanding of the course contents
• ability to provide quantitative (rather than only qualitative) information on the phenomena related to industrial separation operations and on the relevant equipment
• ability to present the topics in a clear and concise way, and with appropriate use of technical terminology
In order to promote study regularity, an increase in the final grade is granted to those who take the exam only once, passing it at the end of the course teaching semester.
Course unit contents: INDUSTRIAL TECHNIQUES FOR PHASE SEPARATION.
RECAP ON VAPOR-LIQUID EQUILIBRIA. Phase diagrams; equilibrium prediction: fugacity, activity and models for their calculation.
SIMPLE VAPORIZATION AND CONDENSATION PROCESSES. Relative volatility; equilibrium flash vaporization; degrees of freedom; ideal separation stage; design of a flash drum; simple (differential) distillation; distillation curves; series of partial vaporizations/condensations.
SEPARATIONS BY CONTINUOUS DISTILLATION. Rectifying columns: total reflux; minimum reflux, pinch point, McCabe-Thiele construction, number of theoretical stages; exhausting columns; complete columns: internal material traffic, minimum reflux and total reflux, optimal feed point, optimal reflux ratio, optimal operating pressure; degrees of freedom of a distillation column; design problems and rating problems.
SEPARATIONS BY BATCH DISTILLATION. Operation of a batch column; operations at: constant reflux, variable reflux, total reflux; separation of multicomponent mixtures.
SEPARATIONS USING STEAM. Steam distillation. Purification of heat sensitive components from non-volatile impurities: prediction of steam consumption. Steam stripping: inert flows and molar ratios; batch operation, continuous single-stage operation, and continuous multi-stage operation, minimum steam consumption.
SEPARATION BY ABSORPTION. Liquid-gas equilibrium; calculation of required theoretical stages and of liquid consumption; diluted absorption.
VAPOR-LIQUID CONTACTING DEVICES. Tray columns: sieve trays, valve trays and bubble-cap trays; total efficiency and its calculation; operability limits of a tray; calculation of tray diameter. Packed columns: random and structured packing; height equivalent to a theoretical stray and its calculation; operability limits of a packed columns; packed column diameter calculation.
Planned learning activities and teaching methods: Classroom lectures (including quick activities in groups), solution of exercises, discussion of case studies, question-and-answer sessions, computer-lab interactive lectures, flipped classes. All class activities are recorded and made available through the Moodle platform. Homework peer assessment is included in the learning activities.
Additional notes about suggested reading: A digital copy of the lecture slides will be made available on the Moodle platform.
