Title (EN) PROCESS FOR THE REMOVAL OF HEAVY METALS FROM LIQUIDS
(FR) PROCÉDÉ D’ÉLIMINATION DE MÉTAUX LOURDS DE LIQUIDES
Abstract:
(EN) The present invention discloses a process for the removal of heavy metals from a liquid comprising heavy metals, wherein hydrochloric acid is added to the liquid, wherein the liquid is brought in contact with a mixture comprising between 30 %vol. and 60 %vol. of an activated carbon catalyst impregnated with sulfur, between 30 %vol. and 60 %vol. of an activated carbon catalyst impregnated with iron and between 5 %vol. and 40 %vol. of a filler material, the total of these three ingredients being 100%vol. The liquid is left in contact with the mixture, the heavy metals are absorbed onto the mixture to obtain a liquid with a depleted level of heavy metals, which liquid is then evacuated from the mixture
(FR) La présente invention concerne un procédé d'élimination de métaux lourds d'un liquide comprenant des métaux lourds, l'acide chlorhydrique étant ajouté au liquide, le liquide étant mis en contact avec un mélange comprenant entre 30 % en volume et 60 % en volume d''un catalyseur au charbon actif imprégné de soufre, entre 30 % en volume et 60 % en volume d'un catalyseur au charbon actif imprégné de fer et entre 5 % en volume et 40 % en volume d'un matériau de remplissage, le total de ces trois ingrédients étant de 100 % en volume. Le fluide est laissé en contact avec le mélange, les métaux lourds sont absorbés sur le mélange pour obtenir un fluide ayant un niveau appauvri en métaux lourds, ledit fluide étant ensuite évacué du mélange.
