| Objectives | |
|---|---|
| KNOWLEDGE AND UNDERSTANDING: UNDERSTANDING THE TERMINOLOGY USED TO MEASURE PROCESS VARIABLES, PROCESS INSTRUMENTATION, INDUSTRIAL VALVES AND AUTOMATIC PROCESS CONTROL. KNOWLEDGE OF BASIC PRINCIPLES FOR TEMPERATURE, PRESSURE, FLOW, LEVEL MEASUREMENTS. ANALYSIS OF LINEAR DYNAMIC SYSTEMS WITH THE LAPLACE TRANSFORM. UNDERSTANDING THE CONCEPT OF FEEDBACK CONTROL (FEEDBACK). APPLYING KNOWLEDGE AND UNDERSTANDING – ENGINEERING ANALYSIS: TO GIVE THE STUDENTS PRELIMINARY AND BASIC KNOWLEDGE IN ORDER TO APPROACH PROCESS PLANT INSTRUMENTATION AND AUTOMATIC CONTROL. KNOW HOW TO CHOOSE THE RIGHT SENSOR FOR MEASURING THE MAJOR PROCESS VARIABLES IN AN INDUSTRIAL PLANT. DEVELOP SIMPLE MACROSCOPIC DYNAMIC MODELS OF INDIVIDUAL EQUIPMENT IN THE CHEMICAL AND FOOD INDUSTRY. APPLYING KNOWLEDGE AND UNDERSTANDING – ENGINEERING DESIGN: MAKE THE CHOICE AND THE GROSS SIZING OF A CONTROL VALVE. DEVELOP SIMPLE FEEDBACK CONTROL SCHEMES, CHOOSE THE CONTROLLER IN A SINGLE LOOP AND SET ITS TUNING PARAMETERS. MAKING JUDGMENTS - ENGINEERING PRACTICE: UNDERSTAND THE PRINCIPLES AND CONTENTS OF THE TECHNICAL DOCUMENTATION OF SENSORS AND VALVES FOR BOTH THE LABORATORY AND THE PROCESS INDUSTRY. KNOW HOW TO EVALUATE THE CHARACTERISTICS AND BENEFITS OF THE VARIOUS TYPES OF SENSORS AND VALVES FOR THE PROCESS INDUSTRY. LEARN TO RECOGNIZE PROCESS INSTRUMENTATION IN A PIPING AND INSTRUMENTATION DIAGRAM (P&ID). COMMUNICATION SKILLS – TRANSVERSAL SKILLS: RECOGNIZE PROCESS VARIABLES, PROCESS INSTRUMENTATION, INDUSTRIAL VALVES AND PROCESS PLANT CONTROL SYSTEMS BASED ON THEIR ENGLISH TERMINOLOGY. KNOW HOW TO APPLY THE ACQUIRED KNOWLEDGE TO DIFFERENT CONTEXTS FROM THOSE PRESENTED DURING THE COURSE, AND TO DEEPEN THE TOPICS USING LEARNING MATERIALS OTHER THAN THOSE PROPOSED IN THE COURSE. LEARNING SKILLS – TRANSVERSAL SKILLS: KNOW HOW TO MAKE A PRELIMINARY MARKET SURVEY TO CHOOSE AN INDUSTRIAL OR LABORATORY SENSOR. KNOW HOW TO MAKE A PRELIMINARY MARKET SURVEY TO CHOOSE A VALVE OR LABORATORY BIB COCK. DISTINGUISH THE DIFFERENCES IN THE DYNAMIC BEHAVIOR OF A CHEMICAL OR FOOD PROCESS IN THE OPEN LOOP OR CLOSED LOOP CONFIGURATION. |
| Prerequisites | |
|---|---|
| FOR THE SUCCESSFUL ACHIEVEMENT OF THE PREFIXED OBJECTIVES, A BASIC MATHEMATICAL KNOWLEDGE IS REQUIRED, IN PARTICULAR ON DIFFERENTIAL CALCULUS, MASTERY OF MACROSCOPIC MASS AND ENERGY BALANCES AT STEADY STATE AND UNDER TRANSIENT CONDITIONS, FUNDAMENTALS OF OF FLUID-DYNAMICS AND TRANSPORT PHENOMENA. |

| Teaching Methods | |
|---|---|
| THE COURSE INCLUDES A TOTAL OF 60H DIVIDED INTO 37H OF THEORY, 14 OF TUTORIALS AND 9 OF INTERACTIVE SOFTWARE AND EXPERIMENTAL LABORATORY. LECTURES ARE PROVIDED IN CLASSES IN THE PRESENCE OF STUDENTS AND IN ENGLISH. ALL COURSE SLIDES ARE MADE AVAILABLE BY THE LECTURER ON THE MS TEAMS® PLATFORM OF UNIVERSITY. IN ADDITION, OTHER NOTES, TEXTS OF PREVIOUS WRITTEN EXAMS AND SOLVED PROBLEMS ARE AVAILABLE. TEACHING INCLUDES THEORETICAL LECTURES CONDUCTED BY THE LECTURER WITH EXTENSIVE USE OF COMPUTERIZED SLIDES AND ANIMATIONS, LECTURE EXERCISES DONE BY THE LECTURER ON THE BLACKBOARD OR SLIDE-BASED, 2 TO 4 HOURS OF INTERACTIVE PROBLEM SOLVING IN COMPUTER CLASSROOM WITH THE USE OF THE EDUCATIONAL SOFTWARE LOOP-PRO CONTROL STATION® OR SIMCET/PITOPS PICONTROL, 2 TO 4 HOURS OF CLASSROOM EXERCISES WITH THE USE OF THE WHEELED FESTO EDUCATION MPS® PA WORKSTATION FOR MEASUREMENT AND AUTOMATIC CONTROL OF LEVEL, FLOW, TEMPERATURE AND PRESSURE. A STUDENT SOFTWARE LICENSE IS MADE AVAILABLE TO EVERY STUDENT WHO REQUESTS IT, PURCHASED ANNUALLY ON THE DIDACTIC LABORATORIES OPERATION FUND OF THE DIDACTIC COUNCIL OF CHEMICAL ENGINEERING. AT THE END OF THE COURSE, EACH STUDENT WHO OPTIONALLY WANTS TO CARRY OUT AN INDIVIDUAL PROJECT WORK TO STUDY THE DYNAMICS OR CONTROL OF A PROCESS, IS ASSIGNED AN ESSAY TO BE DEVELOPED WITH BY MEANS OF THE EDUCATIONAL SOFTWARE AND TO BE DELIVERED TO THE LECTURER THE EXAM. |
| Verification of learning | |
|---|---|
| THE ASSESSMENT OF THE ACHIEVEMENT OF THE SET GOALS IS DONE BY MEANS OF TWO WRITTEN TESTS, EACH LASTING 2 H, WHICH THE STUDENT MAY ASK TO DO EVEN DISTANT OVER TIME, AND, OPTIONALLY, A SIMPLE INDIVIDUAL PROJECT WORK, WHICH IS PREPARED BY THE STUDENT BY MEANS OF THE EDUCATIONAL SOFTWARE AND CAN ADD UP TO 3 POINTS OUT OF 30 FOR THE FINAL MARK. EACH WRITTEN TEST IS MADE UP OF SEVERAL SECTIONS, SOME WITH QUIZZES, OTHERS WITH OPEN ANSWERS, OTHERS WITH CALCULATIONS. THE SECTIONS HAVE A DIFFERENT WEIGHT FOR THE ASSIGNMENT OF THE TEST SCORE: FOR THE TEST NO.1, THE SECTION "CONTROL VALVE SIZING PROBLEM" HAS MORE WEIGHT; FOR THE TEST NO. 2, THE SECTION "DEVELOPING A DYNAMIC MATHEMATICAL MODEL FOR A LUMPED PARAMETER SYSTEM" HAS MORE WEIGHT. EACH WRITTEN TEST IS PASSED WITH THE MINIMUM MARK (18/30) IF THE STUDENT HAS AT LEAST ADDRESSED THE SECTION OF THE TASK WITH THE HIGHEST WEIGHT AND AT THE SAME TIME PROVIDED CORRECT ANSWERS TO 50% OF THE QUESTIONS. IN ORDER TO GET THE MARK “CUM LAUDE”, BOTH THE QUANTITY (COMPREHENSIVE AND NUMERICALLY CORRECT ANSWERS TO ABOUT 90% OF THE QUESTIONS) AND THE QUALITY (APPROPRIATE SCIENTIFIC LANGUAGE AND MASTERY OF THE SUBJECT) ARE TAKEN INTO ACCOUNT IN EITHER OF THE WRITTEN TESTS. |
