TRAITEMENT D'AIR CHARGE EN COV HYDROPHOBES PAR UN PROCEDE HYBRIDE : ABSORPTION – PERVAPORATION

Abstract : Volatile organic compounds (VOC) entail nuisances for humans and the natural environment. Increasing strict rules force the industrials to set up equipments of air treatment ofr their VOC charged effluents. This work studies the technical feasibility of an innovative hybrid process among the at present available techniques: the coupling of an absorption process and a membrane separation, pervaporation. The various aspects of this process are examined: choice of the absorbent, study of hydrodynamics and mass transfer in a packed column, separation of pollutants contained in the absorbent by pervaporation, coupling of the two processes. At the end, an analysis of the process underlines main parameters and their impact on the coupling efficiency. It is shown that hybrid process turns out feasible.
