Gilles HÉBRARD

Actual position and research subject

Gilles Hébrard (57 years old), graduated Doctor (PhD) in water treatment process (1995), Professor at INSA Toulouse in the Chemical and Environmental Engineering Department since 01/09/2007.

My research activities deal with the local and global analysis of hydrodynamic and mass transfer present in gas/liquid contactors. I develop my research activities in TIM (Transfert Interface Mixing) group of TBI (Toulouse Biotechnology Institute).

I stayed as visiting Professor at UBC (University of British Colombia) in Canada in John R. GRACE research group from August 2011 to August 2012.

I have supervised 28 PhD, 5 post-doct and 22 MASTER research; I have published 177 publications and communication with 74 articles in international journal of mark A, 7 patents and one chapter of book.

I teach at INSA mass transfer operation and thermodynamic (Energy and Exergy balance).

I was the head of the Chemical and Environmental Engineering Department from 01/07/2015 (50 students graduate per year) to 01/09/2021 and now I’m in charge of INSA sustainable campus development.

RESEARCH TOPICS

Action 1 : Bubble formation at a flexible and rigid orifice ; gas/liquid mass transfer obtained with a bubble chain in different liquids under test (surfactants, sodium chloride and glucose solution); Determination of liquid side mass transfer coefficient and diffusion coefficient.

Action 2 : Characterisation of hydrodynamic and mass transfer in different types of gas/liquid contactors (bubble columns and spraying column with and without packing, microchannel with Taylor bubble flow) by development of new experimental approaches.

Action 3 : Characterisation of hydrodynamic and mass transfer in spraying column system for COV removing or ozone pulverization; improvement of absorption liquid phase by using an oil/water emulsion developed for the COV removing; decrease of ozone desorption through nozzle modification; modelling of absorption or desorption efficiency.

Action 4 : Development of a new hybrid process by in-line coagulation and flocculation with micro-bubbles in hydrocyclone for drinking water production.

Action 5 : Development of a new scrubber system for a farm biogas upgrading with CO2 and CH4 separation (epurogaz.fr).
