a) (Petro)chemicals & Polymers:
Refining and petrochemicals: After an introduction and overview of refining and the (petro)chemical industry, three specific processes are studied in detail, analyzing as well the flow-sheets, thermodynamic, kinetic and eventual catalytic aspects, the reactor concepts, aspects related to the separation and purification of reactants and products, the energy requirements and the environmental impact, and the process safety. In the context of process intensification, advanced reactor technologies and their modeling are also dealt with.
Polymerization processes: after a general introduction to polymerization processes, the various types of processes are reviewed and illustrated at hand of industrial examples. A special emphasis is put on the production processes of polymers produced in large amounts worldwide, such as polyethylene (HDPE, LDPE), polypropylene (PP), polystyrene (GPPS, HIPS), PVC. Some specific problems, such as the control of polymerization reactors are also addressed.
b) Advanced Separation Technologies:
Separation technologies are the cornerstone in the industry since they contribute with around 75% of the production cost. In addition to simple distillation, absorption or extraction, more complex techniques are required for challenging separations. The following advanced separation techniques will be addressed during the second part of the course:
Enhanced Distillation (Extractive Distillation ; Salt Distillation ; Pressure-Swing Distillation ; Homogeneous Azeotropic Distillation ; Heterogeneous Azeotropic Distillation ; Reactive Distillation).
Batch Distillation (Differential Distillation ; Binary Batch Rectification ; Batch Stripping and Complex Batch Distillation)
Membrane Separations (Gas Permeation and pervaporation ; Membrane contactors).

The students will be individually graded based on the objectives indicated above.
The exam is with a written preparation and oral defense/discussion. It counts for 100% of the mark.
This course combines ex-cathedra teaching and projects/exercises with tutoring.
Processes for the production of (petro)chemicals and advanced reactor technologies:
The theoretical courses are ex-cathedra. The students are encouraged to ask questions. During the course, the students are asked to read, analyze and question a number of scientific papers. Practical sessions are given in the form of exercise sessions.
Advance Separation Processes:
Theoretical classes are complemented with exercises sessions.
One practical session will be performed in the computer room so that the student can control a distillation column (pilot plant) located in Toulouse. The student will be able to change the operation conditions of the column and watch on-live via several web-cam. After the session, the student will do the interpretation of results. This session is carried out in collaboration with the ENSIACET.
