The course deals with the management of large combustion plants, and their interaction with the environment. The Best Available Technologies to reduce polluting emissions during combustion, analyzes transport and storage are based on the European legislation on IPCC, also considering the associated risk. Methods for the estimation, monitoring and control of emissions and the authorization process of production facilities are presented.
The course will cover the topics related to the management of Large Combustion Plants, LCP, and their interaction with the environment. Fuel properties and associated risks are presented, with a focus on the Utilities network monitoring. Combustion process and its environmental impact will be investigated and the Best Available Technology to reduce pollutant emissions in LCP will be analyzed on the base of the 2016 European IPCC BrEFDocument. LCP pollutant monitoring and control strategies will be presented.
The student must be familiar with the characteristics of fossil and alternative fuels, from an energy and environmental impact point of view.
The student must be able to assess the intensity of emissions related to combustion plants, to choose the most appropriate abatement strategies and to carry out their basic sizing.
The student must be able to evaluate the impact in terms of decarbonisation of the processes obtainable with the different strategies presented
The student must understand the effects that natural events (wind and precipitation) have on production sites and which containment actions can be used
The student must know the Strategic Environmental Assessment, Environmental Impact Assessment, and IPPC Permit (Integrated Environmental Authorization) process.

Details on how to prepare for the exam and the degree of depth of each topic will be given during the lessons. The oral exam will mainly focus on the topics covered during the lectures and will aim to assess whether the student has achieved an adequate level of knowledge.
Students with learning disorders ("disturbi specifici di apprendimento", DSA) will be allowed to use specific modalities and supports that will be determined on a case-by-case basis in agreement with the delegate of the Engineering courses in the Committee for the Inclusion of Students with Disabilities
