Method and device for the wet oxidation treatment of liquid waste laden with mineral matter
Abstract:
A method and device for the wet oxidation treatment of liquid waste laden with mineral matter in suspension. The device comprises a reactor including a treatment column, first and second heat exchangers placed upstream and downstream, respectively, of the reactor. The solution to be treated, laden with mineral matter to which an oxidizing gas has been added, is injected into the reactor for treatment after being preheated in the first heat exchanger. When the solution exits the reactor, the hot treated mixture is divided into two hot stream fragments. The first hot treated mixture stream fragment, the flow rate of which is kept constant by a diaphragm column, is used for controlling the temperature of the first heat exchanger and then discharged after being used in the first heat exchanger. The second hot treated mixture stream fragment is directly cooled and discharged when the second hot treated mixture stream fragment leaves the reactor.
