Gas Effluents and Air Quality

Recommended Prerequisites

Calculus III, Thermodynamics and Phenomena Transport.

Teaching Methods

The teaching is provided through lectures and theoretical-practical classes. In the lectures are exposed theoretical concepts and methodologies in the study of problems, together with some application examples. In theoretical practical classes the students must solve problems for applying concepts learned in the lectures. These classes are also designed to solve more complex problems related to the design of the equipments, in which the work and group discussion are promoted.

Learning Outcomes

Sensitize students to the impact of atmospheric pollution on air quality, provide students with knowledge of qualitative and quantitative characterization of gaseous pollutants; familiarize the students with the meteorological phenomena that affect the dispersion of the plume and mathematical models to predict pollutant concentrations in three dimensional space; provide  knowledge on the theoretical foundations of the main technologies of treatment of gaseous effluents; provide the necessary tools for the design and selection of equipments.

Develop the following skills: the theoretical knowledge, capacity for analysis and synthesis; ability to integrate knowledge to solve practical problems.
