Abstract:
Device, system and method for injecting organic matter into a reaction enclosure (2) of a reactor for treatment using a supercritical water oxidation method. The device comprises a body having an inner volume defining a pressurizing capacity (24) in which a mobile assembly (29) is arranged, e.g. a bellows for dividing the inner volume into two variable volume compartments including a compressing capacity compartment (32) and a hydraulic pressurizing capacity compartment (34). The hydraulic pressurizing capacity compartment is preferably connected to the outlet (15) of an aqueous phase liquid/gas separator (14) which separates the liquid and gaseous phases of the effluent leaving the reaction enclosure (2).
Abstract:
A reactor for treating with pressurized water a material in a fluid reaction medium. It comprises a body (2) delimiting a reaction area (10), an inlet (48) for the material to be treated in the reaction area (10), a point (46) for introducing an oxidant into the reaction area (10), at least one outlet for the treated material outside the reaction area (10), the material to be treated follows a path defined in the reaction area between its inlet and its outlet. The point (46) for introducing the oxidant in the reaction area (10) is located downstream from the inlet (48) for the material and is spaced apart from the latter by a certain distance so as to define an anoxic area (20) comprised between the inlet for the material to be treated and the point for introducing the oxidant, an area in which the fluid medium is in anoxia.
Abstract:
A reactor for treating a material in a medium. It includes a body (2) in which is defined a reaction area (10) capable of containing a reaction medium, at least one inlet for introducing the reaction medium into the reaction area, one outlet for discharging effluents out of the reaction area. A protective casing (8) positioned inside the body (2) delimits the reaction area (10). It is spaced apart from the body in order to delimit a confinement area (12) isolating the reaction area of the body. The reaction area and the confinement area are sealably isolated from each other.
Abstract:
A method and device for oxidization of materials in supercritical water. The method involves a) introducing a fluid containing water and an oxidizing agent in a ring-shaped area and through a first end of a substantially tube-shaped reactor comprising an external wall and an internal tube, b) heating the fluid in the ring-shaped area, c) introducing the heated fluid into the internal tube and simultaneously introducing material to be treated into said internal tube at a second end of the reactor, d) mixing the fluid and the material to be treated in a first portion of the internal tube, followed by cooling the obtained mixture in a second portion of the internal tube, and e) isobarically discharging the fluid/oxidized material from the internal tube of the reactor.

Abstract:
Device and installation for injecting matter, particulate matter in particular, into an enclosure, and associated method. The device for injecting matter into a reaction enclosure in a treatment method using pressurized water comprises a pressurizing capacity (24) having an inner volume in which a mobile assembly (29) is arranged, e.g. a bellows which compartments it sealingly into two variable volumes, namely a pressurizing capacity (32) and a hydraulic pressurizing capacity (34). The variable, hydraulic pressurizing capacity of this device is connected to the outlet (15) of the aqueous phase of a liquid/gas separator (14) which separates the liquid and gaseous phases of an effluent leaving the reaction enclosure (2).
