B3-1 Process optimisation

Physics, optics

Year (Module) : 3A (B)
Lecturer :Walter FURST, Patrice PARICAUD, RAFFAELE GIOVINAZZI

Objectives

The aim of this course is to describe the various elements incorporated in the software used for the simulations of industrial processes. This will also result in the presentation of a global overview of the processes.
Process simulation has to take into account models of operation units. As reactors are treated elsewhere, this course will be focused on separation operation units that are very important in many processes. The example presented is the distillation column where coupling between thermodynamics, mass and heat transfer and complex hydrodynamics has to be taken into account, together with energy and mass balance.
The various aspects will be presented and, then, the students will use a column with 26 real plates during a practical lesson.
Besides some lessons are devoted to process optimisation through the use of economical criteria, to the pinch technology and to numerical aspects of process simulation.
The last lessons are devoted to the building of processes using Aspen+ software. During this project, the students will start from the reactor characteristics to develop a process that is economical feasible. This will be done incorporating separation operation units and optimising operating conditions and recyclings.

Course organisation :

The first part of the course concerns the processes structure and, then, gives details concerning an example of separation unit. This will be done through lessons and various exercises.
To illustrate the course a practical lesson is then organised.
The second part of the course is mainly devoted to the process simulation projects. During theses sessions, the students will use a commercial software to develop they own process flowsheet, the professor being mainly there for helping them to understand and to solve simulation problems.
