Objectives

- Understand process operations and unit operations that are part of a chemical process;
- Understand the functioning of the main process units;
- Know the steps "Synthesis" and "Analysis" from a chemical process;
- Know how to count variables, equations and design variables in a material balance problem of a system of process units;
- Solve material balance problems of chemical processes composed of a set of process units and where chemical reactions, separations, recycling and purge may take place.;

Learning outcomes and competences

After this course the student will be able to:
1. Understand the general principles of Chemical Engineering Processes;
2. Understand and interpret process flowsheets;
3. Understand the working principles of most important process units;
4. Formulate a material balance problem for process units and for systems of process units in terms of a non-linear system of equations.

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 system of equations).

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 Chemical 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.

Eligibility for exams

1) Attend the 2 foreseen tests with a non-null classification;
2) Do not exceed the limit number of absences in accordance with the General Regulations for the Assessment of Students in force;
3) Participate in at least one of the scheduled study visits.

Students who have attended previous years are exempt from participating in study visits. Students attending the immediately preceding academic year are exempt from attending classes.

Calculation formula of final grade

The final grade CF is calculated by the formula: CF = CQ + 0.40*T1 + 0.50*T2, T1 and T2 being the midterm tests grade and CQ the quizz grades (Max. 2 out of 20). Approval, or grade improvement, can be achieved by final exam.

Examinations or Special Assignments

Not applicable.

Special assessment (TE, DA, ...)

By exam.

Classification improvement

By exam.
