2018 : Escape Classroom: The Leblanc Process—An Educational “Escape Game” – J. Chem. Educ.

An “escape game” activity is proposed to increase stimulation, team group skills, and adaptability in the chemistry classroom. The students follow in the footsteps of Nicolas Leblanc, a young French chemist, who took part in a contest launched by the French Academy of Sciences in 1775 to produce industrial soda ash. By means of scientific […]

2017: Fast determination of gas-liquid diffusion coefficient by an innovative double approach

Feishi Xu, Mélanie Jimenez, Nicolas Dietrich, Gilles Hébrard Chemical Engineering Science Volume 170, 12 October 2017, Pages 68-76 Abstract Two effective mathematical approaches based on the probability and statistics theory are proposed for obtaining the oxygen diffusion coefficients in gas-liquid systems. The first method was to apply PLIFI (Planar Laser Induced Fluorescence with Inhibition) to […]

2017: Experimental characterization of multi-component absorption in complex liquid: New method and apparatus

David Benizri, Nicolas Dietrich, Gilles Hébrard Chemical Engineering Science Volume 170, 12 October 2017, Pages 116-121 Abstract The Henry’s law constant is required to size absorption processes. However, its experimental determination for multi-component gases in presence of complex liquids remains problematic in the process industry and research field. This work presents a new experimental setup […]

2017: Local hydrodynamic investigation by PIV and CFD within a Dynamic filtration unit under laminar flow

Xiaomin Xie, Claude Le Men, Nicolas Dietrich, PhilippeSchmitz, LucFillaudeau https://doi.org/10.1016/j.seppur.2017.04.009 Separation and Purification Technology Abstract To better understand the hydrodynamics in a Dynamic Filtration module (DF), a local investigation within a complex and confined module named Rotating and Vibrating Filtration (RVF) was scrutinized under laminar flow with viscous Newtonian fluid (Remixing = 45). RVF consists of two […]

2017: Local investigations on the gas-liquid mass transfer around Taylor bubbles flowing in a meandering millimetric square channel

Abstract : Gas-liquid mass transfer around Taylor bubbles moving in a meandering millimetric square channel was locally visualized and characterized in the present study. For that, the colorimetric technique proposed by Dietrich et al. (2013) was implemented. With this technique, the evolution of equivalent oxygen concentration fields in the liquid slugs passing through one and […]

2017 : Study of the initial glycerol concentration effects upon bacterial cells adaptation and biodegradation kinetics on a submerged aerated fixed bed reactor using biocell® packing

Abstract: The present work provides an experimental study of the effect of the glycerol concentration on removal performances in a Submerged Aerobic Fixed-Film (SAF) Reactor performing in batch mode. This study consisted in adding various initial substrate concentrations of synthetic solutions (glycerol) in order to assess their effects on biodegradation kinetics and then on bacterial […]
