Course objectives
Introducing students to air pollution, air pollution control and legislation. Students will apply chemical engineering methodology necessary for design and sizing of process units and technological processes used in air pollution control, define key process parameters and develop mathematical models with the goal of optimizing process conditions and develop integrated processes for air pollution reduction and environmental engineering. The course includes design and sizing of process units for particulate removal and units for the removal of gaseous pollutants (VOC, NOx, SO2), for reduction of indoor, as well as outdoor pollution from stationary and mobile atmospheric emission sources.

Course content (syllabus)
Within the scope of this course, students will be introduced to basic terms and definitions related to pollution of air, pollution sources and sinks, the effects of pollution, mechanisms of pollutant formation, legislation and related subjects. Students will be introduced to sampling and analysis procedures of common and specific pollutants of indoor environments and the atmosphere. The focus will be on technological processes and units for air pollution reduction, accompanied by a detailed analysis of basic characteristics of such units and the development of skills necessary for sizing of such units and optimization of their operation. Basic knowledge will be applied to solving real-world engineering challenges through seminars and laboratory work. Research papers will encompass a defined issue, several proposed technical solutions in relation to current state-of-art, criteria of maximally permissible concentrations, economic aspects, specific requirements of certain processes, etc.
The syllabus by week is as follows:
WEEK 1. Introduction to the problem of air pollution: composition and structure of the atmosphere, a historic overview of pollution and its consequences.
WEEK 2. Pollution of the atmosphere: pollution dispersion, legislation, sources and sinks, main groups of pollutants, monitoring and measuring of emissions.
