Title
(FR) PROCEDE D'EPURATION D'UN EFFLUENT GAZEUX
Abstract
(FR) La présente invention concerne un procédé d'épuration d'un effluent gazeux contenant au moins un composé organique volatil (COV), ledit procédé comprenant au moins les étapes consistant à : (a) disposer d'au moins un solvant eutectique profond (DES) comprenant (aa) au moins un composé de formule (I) R1R2R3R4Y+ X- ; et (bb) au moins un composé (II) qui est un donneur de liaison hydrogène capable de former un complexe avec X- ; et (b) mettre en contact ledit solvant eutectique profond de l' étape (a) avec ledit effluent gazeux à épurer dans des conditions propices à l'absorption dudit COV par ledit DES. La présente invention concerne en outre l' utilisation d'au moins un solvant eutectique profond pour absorber au moins un composé organique volatil contenu dans un effluent gazeux ainsi qu'une composition comprenant au moins un composé organique volatil et au moins un solvant eutectique profond.
