PROCESS FOR THE HEAT TREATMENT OF METALLIC RESIDUES CONTAMINATED BY ORGANIC COMPOUNDS, AND DEVICE FOR ITS IMPLEMENTATION.

摘要

Process and device for the treatment of divided metallic residues contaminated by one or more organic compounds, comprising: a mixing, inside a vessel, of said metallic residues with at least one calcium-magnesium compound capable of reacting exothermically with water; an exothermic reaction of said at least one calcium-magnesium compound by the water that the metallic residues contain; a temperature rise of the metallic residues undergoing an exothermic reaction; a dehydration of said metallic residues during this exothermic reaction; an oxidation of the organic compounds during said mixing, by bringing the metallic residues contaminated by one or more organic compounds mixed with said at least one calcium-magnesium compound into contact with a gas stream at least partly containing oxygen; and discharge, out of the vessel, of a dehydrated and handleable treated product that has a residual content of organic compounds of less than 1% by weight of said treated product.
