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 contami nated by one or more organic compounds, comprising: a mixing, inside a vesse l, of said metallic residues with at least one calcium-magnesium compound ca pable of reacting exothermically with water; an exothermic reaction of said at least one calcium-magnesium compound by the water that the metallic resid ues contain; a temperature rise of the metallic residues undergoing an exoth ermic reaction; a dehydration of said metallic residues during this exotherm ic reaction; an oxidation of the organic compounds during said mixing, by br inging the metallic residues contaminated by one or more organic compounds m ixed with said at least one calcium-magnesium compound into contact with a g as stream at least partly containing oxygen; and discharge, out of the vesse l, of a dehydrated and handleable treated product that has a residual conten t of organic compounds of less than 1% by weight of said treated product.
