Learning outcomes
At the end of the module, the student acquires the skills for the design of plants for the separation of gaseous streams from polluting gases, vapors and solids, and knows in detail: - the technologies and the processes for the production of hydrogen from fossil and renewable sources; - the systems in use and future developments for the hydrogen storage; - safety of hydrogen; - the main uses of hydrogen for the production of energy. In particular, also through practical exercises, the student is able to size the equipment, calculate the yield and selectivity, and choose the best technology among the available systems.
Course contents
Introduction
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
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.
