Reactor Dynamics Investigation Based On Calorimetric Data

Thierry Meyer, Francis Stoessel, Charles Ibrahim Guinand, Michal Dabros

A simple and general procedure has been developed to determine the thermal behaviour of a reactor based on heat balance, PID temperature control, and jacket behaviour. Using only temperature heating/cooling ramps followed by isothermal stages, such a proce ...

Accumulation in fed-batch reactor with multiple reaction scheme

Charles Ibrahim Guinand

Nowadays, the fine chemical industry requires increasingly faster time-to-market as well as economically efficient and safe processes. In addition, the growing product variety needs more versatile production plants able to produce from small amounts up to ...

Thermal Process Safety Based on Reaction Kinetics and Reactor Dynamics

Thierry Meyer, Francis Stoessel, Michal Dabros, Charles Ibrahim Guinand

The specific problem of non-converted reactant accumulation encountered in fed-batch reactor is a challenging task of process safety. In order to avoid such situation that may lead to a runaway reaction, the reaction kinetics and reactor dynamic must be kn ...

FH HES Optimization of Chemical Reactor Feed by Simulations Based on a Kinetic Approach

Thierry Meyer, Francis Stoessel, Charles Ibrahim Guinand

Chemical incidents are typically caused by loss of control, resulting in runaway reactions or process deviations in different stages of the production. In the case of fed-batch reactors, the problem generally encountered is the accumulation of heat. This i ...
