AIMS AND CONTENT

LEARNING OUTCOMES

The course aims at deeply investigating the basics of physical and reaction unit operations providing the tools for their design and selection.

TEACHING METHODS

Frontal lessons.

During the year, homework assignments will be given to facilitate the acquisition of the theoretical concepts discussed in the class.

SYLLABUS/CONTENT

Part 1 (T, 4CUF)

• Transport phenomena: critical analysis of the available correlations to calculate the mass transfer coefficient. Multicomponent diffusion: Stefan Maxwell model; transport phenomena in porous matrices.
• Conventional unit operations: Ponchon-Savarit method for a binary distillation column; design equations for packed bed towers and for tray columns.
• Mixing systems: guidelines for the selection and the design of mixing systems.
• Adsorption: principles; linear and non-linear theories; constant pattern theory.
• Scale-up: regimes, guidelines for the scale up in various unit operations and reactors.
• Process monitoring and control.
• Economical analysis: introduction.

Part 2 (T, 4CUF)

• Ideal and non-ideal reactors (batch, continuous, PFR and CSTR).
• Non-ideal fluid motion in reactors (contact time distribution).
• Models of non-ideal fluid motion: dispersion model, reactors in series and in parallel.
• Fluid mixing.
• Fluid-solid reaction: non reacting core (for constant particle size); reaction rate for spherical particles with decreasing size.
• Fluid-solid reaction: study of the kinetic rate. Reactions in suspension.
• Fluid-solid catalytic reactions (catalyst: solid phase).
• Catalytic reactors.

EXAMS

EXAM DESCRIPTION

Oral examination only. Oral admission is subordinated to the reception of the home project assigned during the year. The registration must be done by registering online and sending an e-mail to the co-teaching teachers within the 7 days before the exam date. On-line registration can be made from the web page:

https://servizionline.unige.it/studenti/esami/prenotazione.

ASSESSMENT METHODS

The Commission consists of at least two components of which (at least) one is a co-teacher of the course; the oral examination lasts for at least 30 minutes. By this means, the Commission is able to verify the achievement of the teaching objectives. If these were not achieved, the student is invited to deepen the study by requesting additional explanations to the teacher responsible.The overall assessment also takes into account the ability to apply theoretical knowledge in solving problems of industrial interest.
