Gilles Hébrard (47 years old), graduated Doctor (PhD) in water treatment process (1995), Professor at INSA Toulouse in the Process Environmental Technology Department since 01/09/2007. My research activities deals 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 LISBP (Laboratoire d’Ingénierie des Systèmes Biologiques et Procédés) that I manage (15 permanent staff and 15 temporary staff) since 2010. I stayed as visiting Professor at UBC University in Canada in the research group of John R. GRACE from August 2011 to August 2012.

I have supervised 12 PhD, 5 post-doct and 20 MASTER research; I have published 43 articles in international journal of mark A, 4 patents and one chapter of book.

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

 

 

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).

Action 3 : Characterisation of hydrodynamic and mass transfer in spraying column system for COV removing; improvement of absorption liquid phase by using an oil/water emulsion developed for the COV removing; modelling of absorption 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.
