Industrial processes and scale-up

A.Y. 2019/2020
Overall hours
Learning objectives
The objective of the course is to emphasize the importance of scale-up methodology for the unit operations in chemical plants (reaction and separation processes), to give the theoretical basis for a correct approach to a scaling-up and to introduce the simulation science and the process simulation. The correct theoretical and experimental approaches of this kind of study will be presented and discussed; different industrial examples will be considered.
Expected learning outcomes
At the end of the course the students will be able to use simulation plant software for the project and optimization of a chemical plant, to analyze a chemical process (reaction or separation) from a laboratory scale experiment to a possible industrial process layout; to apply kinetic and thermodynamic models for scale up development of new technologies.
Course syllabus and organization

Unique edition

Course syllabus
The course will be devoted to a specific introduction of the scaling-up methodology for chemical processes from a chemical and an engineering point of view. Both chemical reactions and separation processes will be taken into account. More in detail, the following topics will be explained and discussed:

- Scaling-up of a chemical operation: meaning and importance
- Laboratories and pilot-plant studies
- Models for the interpretation of experimental data and simulation of a chemical unit operations: steady-state and dynamic models
- Physical and chemicals models
- Pilot plants: raw materials, mock-ups, degree of freedom, constructive materials, test program and use of results
- Experimental techniques in scaling-up methodology
- Applications to industrial process development: industrial examples and case-histories
- Control technology in chemical processes
- Environmental and regulatory issues
- Use of simulation softwares in the scaling-up: PRO II. Tutorial of these programs and their use for several aspects involved in the topics of the course.
- Immersive Training system for a virtual visit in a Crude Distillation Unit plant.
Prerequisites for admission
The basic prerequisites are a good knowledge of physical chemistry and a basic knowledge of transport phenomena, chemical reactors, distillation and absorption columns, fluid phase equilibria.
Teaching methods
The course will be based on 48 h of lessons in room in which: 1) theory of scale up will be explained (40%); 2) simulation software of chemical plants will be introduced and used (40%); 3) industrial case studies will be considered (20%). Moreover, during the course, a visit in the Radici plant in Novara will be proposed and organized.
