Systems and methods for heating, reacting, and/or treating a stream containing oxidizable matter. Recycle reactor is used alone or in conjunction with plug-flow reactor. Density differences in the recycle reactor facilitate flow within the recycle reactor without substantial external heat exchange.

Heating and reaction system and method using recycle reactor

Oxidation reactions occurring in a plug flow reactor under conditions approximating supercritical water conditions are controlled by injecting a process stream of water and two reactants in non-stoichiometric proportions into the reactor and causing the process stream to flow through the reactor. Water is injected at one or more points downstream from the inlet to lower the temperature of the process stream and additional reactant injected to re-start the reaction. The quench and re-start process is repeated until substantially all oxidizable material in the process stream has be oxidized.

Method for controlling reaction temperature

A method for treating waste water streams by introducing a mixture of pre-heated waste water and an amount of oxidant lower than that required to oxidize all the organic matter in the waste stream into the front port of an elongate tubular reaction chamber. The amount of oxidant is preferably high enough, however, to raise the temperature of the stream in the reaction chamber to 750.degree.-1,200.degree. F. A first injection side port is preferably located downstream from the front port of the reaction chamber at a distance at which the temperature has reached a maximum value, and 90-100% of the available oxidant has been consumed. Oxidant and water may be simultaneously injected through the first port, in a manner that the amount of oxidant is adequate to oxidize a specified amount of organic matter, and the amount of water is effective to counterbalance the heat produced by the reaction of the co-injected oxidant with the respective organic matter. At the point that 90-100% of the newly injected oxidant has been consumed, a second port is used to introduce more oxidant and water in a similar manner and under similar conditions. More ports are also used, following similar rules, until the organic matter has been substantially exhausted. The reaction chamber preferably has a multiplicity of ports, so that depending upon the particular stream, its BTU value, and other parameters, the appropriately spaced ports are selected as injection ports. Highly improved output is achieved by the process and apparatus of the present invention.

Method for treating waste water streams by oxidation in high temperature

An apparatus for treating waste water streams is constructed by introducing a mixture of pre-heated waste water and an amount of a oxidant lower than that required to oxidize all the organic matter in the waste stream into the front port of an elongate tubular reaction chamber maintained at supercritical temperatures and pressures. The amount of oxidant is high enough, it initially raise the temperature of the stream in the reaction chamber to 750-1,200.degree. F. A first injection side port is located downstream from the front port of the reaction chamber at a distance at which the temperature has reached a maximum value, and 90-100% of the available oxidant has been consumed. Oxidant and water are simultaneously injected through the first port, in a manner that the amount of oxidant is adequate to oxidize to oxidize a specified amount of organic matter, and the amount of water is effective to counterbalance the heat produced by the ration of the co-injected oxidant with the respective organic matter. At the point that 90-100% of the newly injected oxidant has been consumed, a second port is used to introduce more oxidant and water in a similar manner and under similar conditions. More ports are also used, following similar rules, until the organic matter has been substantially exhausted.

Supercritical oxidation apparatus for treating water with side injection

A high pressure and high temperature reactor, especially operating under supercritical water conditions combined with corrosive atmosphere. The reactor comprises a reaction chamber and a pressure vessel, which surrounds the reaction chamber. It has high integrity since it has only one penetration in the pressure vessel, and its size is minimized due to induced turbulent flow of the ignited reaction mixture.
