Patent ID: 7708897

Claim:
Device for injecting organic matter into a reactor having a reaction enclosure for treating the injected organic matter using a supercritical water oxidation method, with the reaction enclosure having an inlet into which the organic matter is injected from said device under pressure and an outlet for generating a liquid/gas phase from the treatment of said organic matter wherein the device comprises a body having an inner volume defining a pressurizing capacity ( 24 ) in which a mobile assembly is arranged for dividing the inner volume into two variable volume compartments including an organic matter compressing capacity compartment ( 32 ) and a hydraulic pressurizing capacity compartment ( 34 ) and with the device being connected to said reactor through a valve assembly for controlling communication between the device and the inlet and outlet of said reaction enclosure such that fluid from the outlet of the reaction enclosure will be fed into the hydraulic pressurizing capacity compartment ( 34 ) of the device when communication between the outlet and the device is established via the valve assembly.
