| Prerequisites | |
|---|---|
| PROPAEDEUTICITY: PRINCIPLES OF CHEMICAL ENGINEERING THE COURSE REQUIRES KNOWLEDGE OF BASIC CONCEPTS OF MATHEMATICS AND PHYSICS IN THE DOMAIN OF INDUSTRIAL ENGINEERING, INCLUDING THE THERMODYNAMICS OF PHYSICAL EQUILIBRIA AND THERMAL TRANSFORMATIONS. BASIC CONCEPTS RELATED TO THE TRANSFER OF MATTER, ENERGY, AND MOMENTUM ARE ALSO REQUIRED. FOR STUDENTS OF THE DEGREE COURSE IN CHEMICAL ENGINEERING, THESE PREREQUISITES ARE MET WITH THE COMPLETION OF PROPAEDEUTIC COURSES. |

| Teaching Methods | |
|---|---|
| THE TEACHING INCLUDES 50% OF METHODOLOGICAL AND THEORETICAL CLASSROOM LECTURES DELIVERED IN ENGLISH AND APPROXIMATELY 42% OF TUTORIALS IN THE CLASSROOM (DELIVERED IN ITALIAN). THE REMAINING 8% OF ASSISTED TEACHING INCLUDES LABORATORY EXERCISES ON THREE SIGNIFICANT UNIT OPERATIONS (DISTILLATION, HEAT EXCHANGERS, HUMIDIFIERS). ATTENDANCE AT COURSES IS STRONGLY RECOMMENDED. |
| Verification of learning | |
|---|---|
| LEARNING IS ASSESSED THROUGH A WRITTEN TEST AND AN ORAL TEST, BOTH NECESSARY TO PASS THE EXAM. THE WRITTEN TEST AIMS TO VERIFY THE LEARNING OUTCOMES RELATED TO KNOWLEDGE AND THE ABILITY TO APPLY UNDERSTANDING TO JUDGEMENT AUTONOMY AND WRITTEN COMMUNICATION SKILLS. IT LASTS 240 MINUTES AND INVOLVES SOLVING THREE EXERCISES ON THREE DIFFERENT UNIT OPERATIONS, EACH COMPOSED OF TWO QUESTIONS OF GRADED DIFFICULTY: A FIRST PART WORTH 6 POINTS AND A SECOND PART WORTH 4 POINTS. THE FIRST PARTS REQUIRE THE STANDARD APPLICATION OF CALCULATION PROCEDURES, WHILE THE SECOND PARTS REQUIRE THE CRITICAL ELABORATION OF THEORETICAL KNOWLEDGE. EXERCISES CAN BE DONE CONSULTING PERSONAL NOTES, TEXTBOOKS, AND THE CHEMICAL ENGINEER'S HANDBOOK, WHOSE CORRECT CONSULTATION WILL ALLOW VERIFYING THE STUDENT'S ABILITY TO RETRIEVE AND USE DATA FROM BIBLIOGRAPHIC SOURCES. PASSING THE WRITTEN TEST IS CONSIDERED ACHIEVED WHEN THE STUDENT CORRECTLY IDENTIFIES THE SOLUTION TECHNIQUE AND ANSWERS THE FIRST QUESTION OF THE THREE PROPOSED EXERCISES OR ALTERNATIVELY SOLVES BOTH QUESTIONS OF TWO OF THE THREE PROPOSED EXERCISES. PASSING THE WRITTEN TEST IS NECESSARY TO ACCESS THE ORAL TEST. THE ORAL TEST CONSISTS OF A 30-45 MINUTE INTERVIEW AIMED AT VERIFYING THE STUDENT'S KNOWLEDGE AND MASTERY OF DESIGN ELEMENTS, JUDGEMENT AUTONOMY, AND ORAL COMMUNICATION SKILLS. IN THE ORAL TEST, ASPECTS THAT THE CORRECTION OF THE WRITTEN TEST FAILED TO CLARIFY CAN ALSO BE DEEPENED. THE GRADE RECEIVED BY THE STUDENT IN THE WRITTEN EXAM NEEDS TO BE CONFIRMED BY THE ORAL EXAM. THE FINAL EVALUATION MAY VARY FROM THE WRITTEN EXAM, TYPICALLY BY UP TO A MAXIMUM OF 5 POINTS. IT IS ESSENTIAL TO PASS THE EXAM WITH A MINIMUM GRADE TO DEMONSTRATE THE ABILITY TO IDENTIFY THE PHYSICAL PRINCIPLES ON WHICH THE VARIOUS UNIT OPERATIONS ARE BASED, OUTLINE THE STRUCTURE OF THE EQUIPMENT IN WHICH THEY ARE CONDUCTED, AND CORRECTLY WRITE THE BALANCE AND RATING EQUATIONS NECESSARY FOR THE PROJECT. THE STUDENT REACHES THE LEVEL OF EXCELLENCE IF THEY HAVE CORRECTLY ANSWERED ALL QUESTIONS OF THE THREE EXERCISES PROPOSED IN THE WRITTEN TEST AND DEMONSTRATE IN THE ORAL TEST FULL KNOWLEDGE OF THE DESIGN PROCEDURES AND OPERATING CONDITIONS OF THE EQUIPMENT USED IN THE UNIT OPERATIONS COVERED IN THE TEACHING, AS WELL AS THE ABILITY TO CRITICALLY USE THE CONCEPTS LEARNED, BEING ABLE ALSO TO APPLY THEM TO TYPES OF PROBLEMS DIFFERENT FROM THOSE DISCUSSED IN THE CLASSROOM. |
