Learning outcomes |
In this CU it is intended that the student learn how to identify the different unit operations from the chemical industry, classify them based on physical-chemical principles and transport phenomena involved, know their design variables and calculation methodology.
At the end of the CU students should be able to:
1. Perform size analysis of particulate solids and understand the concept of Bond diameter.
2. Understand the movement of particles in a fluid and determine the settling rate.
3. Know the different types of filters and apply filtration basic equations.
4. Understand leaching and liquid-liquid extraction and write balances and equilibrium relations to determine the number of stages to achieve a specific yield.
5. Characterize gas-vapour systems and use psychrometric charts.
6. Understand vapour-liquid equilibrium and write equilibrium equations and mass balances to determine the number of theoretical plates in distillation or gas absorption columns.

Teaching Methodologies and Assessment Criteria |
TEACHING METHODOLOGIES
The teaching-learning activities consist of theoretical-practical lectures. The theoretical lectures are interactive, and exposure of matter aims to encourage the participation of students. In the theoretical-practical lessons where practical questions are to be solved, the teacher only guides the students with general comments and only gives theoretical explanations when a general difficulty in solving the proposed problem is observed.
EVALUATION
Evaluation comprises 2 tests and/or 1 exam (80%) and oral presentation and defense of preliminary design of a unit operation (20%).
Students succeeded by frequency are dispensed from the exam.
To obtain frequency: Weighted average of the 2 tests > 6 values and perform the project .
Approval by frequency: Weighted average of the 2 tests >/= 10, with a minimum of 6 in each test, and grade >/= 10 in the design of a unit operation.
Approval by Exam: Exam mark >/= 10 values and grade >/= 10 in the project.
