Objectives

1. BACKGROUND: Chemical Engineering is the design, construction and operation of Chemical Processes. A Chemical Process is a set of physical and chemical operations ocurring in Process Units in a precise sequence. The development of Chemical Process is generally considered to be accomplished in a two step procedure: Synthesis (leading to process flowsheet) and Analysis (the quantitative process evaluation through final economic analysis). Material Balances is the very first task in the Analysis of chemical processes.  2. SPECIFIC AIMS: Identify and understand process units and its fundamentals; Know about Synthesis and Analysis of chemical processes; Know how to count variables, equations and design variables in a material balance problem to a system of process units and involving chemical reaction, separations, recycling and purge. 3. PERCENT DISTRIBUTION Scientific component (establishes and develops scientific bases): 20%; Techonological component (apply to design and process operation): 80%.

Learning outcomes and competences

After this course the student is able to: - Understand the general principles of Chemical Engineering Processes; - Understand Process Flowsheet and the working principles of most important Process Units; - Formulate a Material Balance problem for Process Units and for Systems of Process Units in terms of a non-linear system of equations (the modular approach method); - Use computers to numerically solve a Material Balance problem.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Rudiments of algebra (systems of equations), numerical methods (solving non-linear equations) and some practice of speadsheets (like excel).

Program

I. Introduction. Definitions. Chemical Engineering, Chemical Process, Unit Operations, Process Units. Process Synthesis and Analysis. Flowsheet. Examples of Process Units and Chemical Processes; II. Chemical Processes: Examples of Chemcial Processes (Industrial Alcohol, Seawater Dessalination); III. Synthesis of Chemical Processes (explained by the resolution of a specific problem); IV. Material Balances for Process Units (without chemical reaction): General analysis of a material balance problem: counting of variables and equations, and identification of design variables. Material balances for equilibrium stage units: vapor-liquid, liquid-liquid and solid-liquid separations; V. Material Balances with Chemical Reaction: Stoichiometry. Reactant conversion and reaction extent. Independent balance equation for chemical reactors. Examples of material balances in the cases of ocurring chemical equilibrium or undetermined stoichiometry; VI. Material balances for Systems of Process Units: Processes with Recycle and Purge. Use of Modular Approach to solve material balances in systems of process units.

Eligibility for exams

1) Do not exceed the limit of class absences established in FEUP's regulations; 2) To participate in one of the study visits; 3) Has a positive grade in his teamwork (TW => 10).

Calculation formula of final grade

The final grade is calculated by the formula: FinalG =0.35 FG + 0.65 EG if FG > EG FinalG = EG if FG =< EG where: FinalG – final grade FG – Frequency grade = (MD + TW)/2 MD – midterm test TW - Team work To access examinations, students must have TW => 10. FG = EG EG – Grade of the final exam
