Procédé d'adsorption et régénération électrothermique sur textile de carbone activé - Une solution pour la problématique des COV dans des gaz à fort potentiel énergétique

Abstract : An adsorption-electrodesorption process on activated carbon fabric is deemed to address the issue of volatile organic compounds at trace concentrations in methane-rich gases: \emph{biogas} and \emph{natural gas}. The experimental procedure is divided into two connected sections so as to, firstly, assess the potential of several materials and define the most relevant in the working conditions by means of modelling chemical and physical phenomena adsorption-bound and desorption-bound; secondly implement this fabric in a specific lab-scale pilot-unit, designed to perform continuous treatment. Adsorption and desorption in steady conditions of the studied organic volatile compounds: toluene, isopropanol, methylene chloride, ethanethiol, octamethylecyclotetrasiloxane et tetrahydrothiophene, on several activated carbon fabrics are characterised, modelled et quantified in order to design the lab-scale pilot-unit. Numerical simulations are applied to fluid dynamics through fabric filters and continuous adsorption models. This approaches a global understanding upon limits conveyed by the customary definition of physical models in similar process cases. Experimental results performed with the lab-scale pilot-unit brings a first data set to openly discuss the relevancy of the suggested process in order to remove noxious compound from biogases and natural gas.
