Procédé propre pour le traitement des composés organiques volatils par absorption sélective

Abstract : The present manuscript presents the classical steps for designing the clean gas-liquid absorption technique for the removal of chlorinated Volatile Organic Compounds (VOCs). The first step consists in determination of the vapour-liquid equilibrium of three chlorinated VOCs of industrial significance in three high-boiling solvents. ln the second step, the diffusion coefficients of VOC in high-boiling solvent were measured. The comparison between correlations and experiment shows that the correlation of Wilke-Chang is in good agreement with the experiment for DCM. The last step concerned the performance of laboratory structured packed column for absorption of VOCs by a high-boiling solvent. The high efficiency were obtained showing, thus, the feasability of scrubbing technique to remove the chlorinated VOCs. The measurement of the mass transfer coefficient of structured packed column allowed to point up the particularity of such systems.
