Title: PROCESS FOR THE REMOVAL OF HEAVY METALS FROM FLUIDS
Abstract:
The present invention discloses a process for the removal of heavy metals and/or dioxins from a fluid comprising heavy metals, wherein the fluid 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 fluid is left in contact with the mixture, the heavy metals and/or dioxins are absorbed onto the mixture to obtain a fluid with a depleted level of heavy metals, which fluid is then evacuated from the mixture.
