Obiettivi
LEARNING OUTCOMES: EXPECTED LEARNING OUTCOMES AND COMPETENCES
THE COURSE AIMS TO PROVIDE OR, IN SOME CASES, TO IMPROVE THE PROCESS EQUIPMENT DESIGN TOOLS IN THE CHEMICAL AND FOOD INDUSTRIES.
CONCERNING THE DESIGN OF THE EQUIPMENTS THAT STUDENTS ALREADY KNOW, IN THIS COURSE THE CONNECTIONS BETWEEN THERMODYNAMICS AND CHEMICAL ENGINEERING PRINCIPLES ARE EMPHASIZED, EVEN FOR SYSTEMS UN-IDEAL AND MULTI-COMPONENTS.
AN ADDITIONAL TRAINING TARGET IS TO INCREASE THE NUMBER OF UNIT OPERATIONS KNOWN, HIGHLIGHTING THE PROCEDURE THAT MAKE POSSIBLE TO DEVELOP A GENERAL METHODOLOGY FOR THEIR DESIGN.
MOREOVER, SOME CONCEPT AND TOOLS EASY TO MANAGE FOR MINIMIZATION OF OPERATING COST AND ENERGY CONSUMPTION IN THE PLANTS.

KNOWLEDGE AND UNDERSTANDING
UNDERSTANDING UNIT OPERATIONS DESIGN METHODOLOGIES AND SELECTION OF MODELS MORE SUITABLE TO DESIGN UNIT OPERATIONS AND EQUIPMENTS, CONSIDERING PRODUCT COMPOSITION AND OPERATING CONDITIONS. THE GENERAL APPROACH FOR DIFFERENT UNIT OPERATION DESIGN IS SHOWN AND DISCUSSED.

APPLYING KNOWLEDGE AND UNDERSTANDING
BEING ABLE TO CHOOSE AND USE MATHEMATICAL MODELS TO DESIGN THE MOST APPROPRIATE EQUIPMENT AND THE MOST COMMON PLANTS IN THE CHEMICAL AND FOOD PROCESSING INDUSTRY.

MAKING JUDGMENTS
IN UNIT OPERATION DESIGN, TO KNOW HOW TO SET THE DESIGN RELATED TO THE SYSTEM, TO THE SCOPE TO BE ACHIEVED (COMPLETE RIGOROUS DESIGN, APPROXIMATE SOLUTION OR FIRST TRIAL APPROACH) AND RELATED TO THE TOOLS AND THE TIME AVAILABLE.
IN THE PLANT OPERATION, TO BE ABLE TO INTERACT WITH THE UNIT OPERATION AND EQUIPMENT THROUGH THE SET OF PROCESS PARAMETERS, MAKING IN A SHORT TIME A QUALITATIVE PREDICTION OF THE PLANT DYNAMIC ANSWER.

COMMUNICATION SKILLS
TO IMPROVE THE TECHNICAL LANGUAGE AND BE AWARE OF USING COMMUNICATION PROTOCOLS.

LEARNING SKILLS
TO KNOW HOW TO APPLY THE ACQUIRED KNOWLEDGE ALSO TO DIFFERENT ENVIRONMENTS WITH RESPECT TO THOSE PRESENTED DURING THE COURSE. TO UNDERSTAND DESIGN CALCULATION MODEL FOR UNIT OPERATIONS, WITH RESPECT TO THOSE INCLUDED AND ALSO TO THOSE NOT INCLUDED IN THE COURSE.
Prerequisiti
PREREQUISITES
PREREQUISITES ARE MASTERING THE BASIC CHEMICAL ENGINEERING CONCEPTS, MAINLY THE THERMODYNAMICS OF IDEAL SYSTEMS. MOREOVER, A BASIC KNOWLEDGE OF THE MAIN EQUATION OF STATE (SRK, PR FOR EXAMPLE) AND THE BINARY INTERACTION COEFFICIENT TO ADAPT EOS TO REAL SYSTEMS IS REQUIRED. OTHER PREREQUISITES ARE THE KNOWLEDGE OF MATERIAL, ENERGY AND MOMENTUM BALANCES, THE KNOWLEDGE OF THE CHEMICAL ENGINEERING FLUID DYNAMICS AND TRANSPORT PHENOMENA, THE KNOWLEDGE OF A BASIC PROCESS CONTROL.
