Title (EN) PROCESS FOR THE DESTRUCTION OF CEMENT, ASBESTOS-CONTAINING MATERIAL AND/OR OTHER MATRIX MATERIAL BY SIMULTANFEOUSLY SUBJECTING THE MATERIAL TO CAVITATION AND ACID-BASED CHEMICAL REACTION
(FR) PROCÉDÉ DE DESTRUCTION DE CIMENT, DE MATÉRIAU CONTENANT DE L'AMIANTE ET/OU D'UN AUTRE MATÉRIAU DE MATRICE PAR SOUMISSION SIMULTANÉE DU MATÉRIAU À UNE CAVITATION ET RÉACTION CHIMIQUE À BASE D'ACIDE
Abstract:
(EN) An accelerated process for the complete destruction of a matrix material, such as a matrix material including cement and/or asbestos-containing materials (ACMs), is disclosed. The process comprises forming a slurry or suspension by combining the matrix material with an acid solution (including, for instance, acid waste, which can also be neutralized by the process), causing acid-based chemical reactions in the slurry that cause the destruction of the matrix material. Simultaneously to the chemical reactions, the slurry or suspension is subjected to cavitation, which synergistically cooperates with the chemical reactions to accelerate matrix material destruction. The matrix material can be ground and polarized prior to being submerged in the acid solution to form the slurry. The slurry can be subjected to hydrothermal treatment. Inert secondary raw materials (SRMs) that are non-hazardous to the environment and human health can be obtained from the process.
(FR) L'invention concerne un procédé accéléré de destruction complète d'un matériau de matrice, tel qu'un matériau de matrice comprenant du ciment et/ou des matériaux contenant de l'amiante (ACM). Le procédé comprend la formation d'une bouillie ou d'une suspension par combinaison du matériau de matrice avec une solution acide (comprenant, par exemple, des déchets acides, qui peuvent également être neutralisés par le procédé), provoquant des réactions chimiques à base d'acide dans la bouillie qui provoquent la destruction du matériau de matrice. Simultanément aux réactions chimiques, la bouillie ou la suspension est soumise à une cavitation, qui coopère de manière synergique avec les réactions chimiques pour accélérer la destruction de matériau de matrice. Le matériau de matrice peut être broyé et polarisé avant d'être immergé dans la solution d'acide pour former la bouillie. La bouillie peut être soumise à un traitement hydrothermique. Des matières premières secondaires inertes (SRM) qui sont non dangereuses pour l'environnement et la santé humaine peuvent être obtenues à partir du procédé.
