Affordable and clean energy Industry, innovation and infrastructure Sustainable cities Responsible consumption and production

Academic Year 2021/2022

Learning outcomes

The reduction of the environmental impact of combustion processes: analysis and design of industrial process for the treatment of gaseous effluents through separation: adsorption tower, cyclones, fabric filters, membranes.

The production, use, and storage of hydrogen.

The course is intended to provide an in-depth analysis of the problems connected with the sustainability of energy production 

Course contents


Elements of thermochemistry, processes of interest involving the separations of components in mixture.

Separation technology

The design of tray adsorption tower and random adsorption tower.

The design of cyclones and channel filters


Hydrogen production from non-renewable sources through natural gas reforming, naphtae, coal and through biomass gasification/pyrolosis (grey hydrogen), with and without CCS (blue hydrogen), 

Hydrogen production from renewable sources (green hydrogen): water electrolysis, soda-chlorina process.

Hydrogen Safety of energy processes with particular reference to hydrogen fires and explosions.

Hydrogen Storage: gas, liquid, LHOC  

Use of hydrogen: Fuel cells

Teaching methods

Theoretical lessons in the classroom with projection of slides.

Exercises consisting in the dimensioning and the verification of gas and dust treatment plants.

Assessment methods

The exam consists of a written test followed by an oral colloquium on the theoretical aspects of the course.

In order to be eligible for the oral test, the student must have previously passed the written test.

The written test is based on the specific topics of separation techniques with adsorption, with cyclones and filters and is valid for 2 years.

The oral test consists of an individual interview and ensures the acquisition of the candidate's knowledge on the membrane separation and hydrogen production, storage and utilisation.

The score of the exam is expressed through a single vote.

Passing the exam will be guaranteed to students who have demonstrated operational capacity and knowledge of the theoretical concepts, in relation to the key concepts illustrated in the course.

The failure of both written or oral exam may be due to insufficient knowledge of the key concepts, and/or to the lack of mastery of technical language.

Teaching tools

The teaching material presented at the lesson will be made available to the student electronically. All slides presented during the course will be available online.

During the lessons, small scale instruments and equipment for the separation and the production of hydrogen (structured monoliths, catalytic foams) will be shown.
