<p>Herein described is a process for the hydrothermal treatment of asbestos and/or materials containing asbestos in supercritical water (Supercritical Water, SCW), that provides for the withdrawal ( 3 ) of water from a tank ( 2 ), the transformation ( 5 ) of the water in supercritical water, the reaction of the supercritical water with asbestos or with material containing asbestos in a suitable environment ( 8 ) by means of a hydrolysis process, the cooling ( 14 ) of the waste water, the filtering ( 15 ) of the waste water, the collection of the waste water in a tank ( 17 ). Herein is also described a plant for the treatment of asbestos and/or materials containing asbestos comprising a water tank ( 2 ), a withdrawal pump ( 3 ) associated to said tank ( 2 ), a furnace ( 4 ) containing a serpentine coil ( 5 ) fed by said withdrawal pump ( 3 ) for the transformation of the water in supercritical water and a reactor ( 8 ) for the reaction of the supercritical water with asbestos and/or with the material containing asbestos, heat exchange means ( 14 ) for cooling the waste water from said furnace ( 4 ), and filtering means ( 15 ) of the water positioned at the output of said exchange means ( 14 ) and collection means ( 17 ) of the cooled and filtered waste water.</p> |
