2. LEARNING OUTCOMES
Learning Outcomes | |
| After the successful completion of the course, students will be able to: •Understand phase equilibrium issues (gas, liquid and solid phase) of binary and multi-component mixtures and apply basic laws, eg, Henrys law, Raoults law, Daltons law, etc. •Understand the reasons that limit the rate of mass transfer between two or more phases, whether in dilute or dense mixtures. •Apply analytical, numerical and graphical methods to solve distillation, absorption and extraction processes in packed/tray columns and design cooling towers and sedimentation processes. •Understand in depth the physical principles governing the design and analysis of unit operation devices and design them using analytical and empirical techniques. More generally, after successful completion of the course (descriptive indicator 6 of the European Qualifications Framework) students are expected to acquire the following knowledge, skills and abilities: Knowledge: •Understanding the operation of basic unit operations. • Learning the basic types and layouts of unit operations devices. • Designing and analyzing unit operations through function equations and mass and/or energy balances. •Understanding the concepts of mass transfer rate and phase equilibrium. Skills: • Solving simple and complex problems of unit operations. •Critical understanding of theories and principles of balances and separations. •Solve design problems using analytical and graphical methods. • Development of the ability to mathematically describe physical processes. Abilities: •Critical ability to choose the appropriate unit operations method. • Application of the knowledge of the engineer in dealing with problems of design and analysis of unit operations. • Selection and application of the most suitable methods for solving design and analysis problems. • Development of critical thinking and synthesis of necessary knowledge. | |
| |
| The general skills that the student should have acquired and that the course is aimed at, are: •Research, analysis and synthesis of data and information. • Application of theoretical knowledge in practice. •Decision making on targeted and general problems. •Elaboration of independent work. |
3. COURSE CONTENTS
| The course is divided into teaching chapters, as follows: CHAPTER 1: INTRODUCTION TO UNIT OPERATIONS •Introduction to unit operations and basic concepts •Basic physical processes, classification of unit operations and most important systems •Definitions, quantities and most important laws that govern physical processes •Types of unit operations and typical examples CHAPTER 2: DISTILLATION • Vapor-liquid balance • Fractional distillation with constant and variable molar flows •Methods of analysis for tray/stage distillation columns •Special distillations CHAPTER 3: ABSORPTION •Gas-liquid balance •Packed bed Absorption columns •Analysis methods for thin and dense mixtures CHAPTER 4: LIQUID - LIQUID EXTRACTION • Ternary fluid systems •Methods for calculating theoretical grades •Upflow and counterflow devices for partially and immiscible solvents CHAPTER 5: DEHYDRATION •Basic definitions of humidification •Air-water cooling tower design CHAPTER 6: SEDIMENTATION •Basic principles of sedimentation •Design of settling tanks |
4. TEACHING METHODS – ASSESSMENT
| MODE OF DELIVERY | Face-to-face and distance learning: live and remote presentation with the help of PC and slide show. Auxiliary use of a whiteboard to solve exercises and further explain the theory. | ||||||||||||||||||||||||
| USE OF INFORMATION AND COMMUNICATION TECHNOLOGY | • Use of I.C.T in face-to-face and distance teaching: presentations, exercises and examples. • Use of I.C.T in communication with students: promotion of teaching material, announcements, assignments, etc., via eClass. | ||||||||||||||||||||||||

| ASSESSMENT METHODS | •Evaluation language: Greek •Alternative ways of examination and scoring: 1. Final written exam in June or September: 100%. 2. Optional written work - optional weekly projects and final written exam in June or September: 35% + 75% = 110%. The student receives the highest possible grade that can result from the above cases. •Student evaluation method: Written exam with design and analysis problem solving (formative, conclusive). Written design and analysis problem solving work (formative, inferential). The above grading algorithm is available to students through the course website. |
