摘要： The present invention relates to a process of oxidation, of the wet oxidation or ozonization type, of a liquid contained in a reactor. The gas of the gas headspace is aspirated into the liquid, and the portion which is not dissolved in the liquid is recovered in the gas headspace. The agitation means creates a flow of liquid immediately adjacent to the end of the duct opening into the liquid, and generates a gas/liquid dispersion in the zone, within which the liquid reacts with the gas, then conveys and ejects the said dispersion at its periphery, such that the gas is dissolved in the liquid in the zone extending from the agitation means to the surface of the liquid. The said process is particularly suitable for oxidations which make use of considerable quantities of oxygen or of ozone. It is particularly applied for the oxidation of papermaking liquors.

摘要： A process for pre-treating a spent caustic stream prior to oxidation which includes countercurrent multi-stage elevated temperature solvent extraction of dissolved organic material from the spent caustic using a solvent to yield a spent caustic raffinate containing only residual amounts of organic solute and steam distilling the spent caustic raffinate to remove the residual organic solutes, yielding a pretreated spent caustic stream substantially free of organic material which is then subjected to wet air oxidation and thereafter to ozonolysis to yield a wastewater stream having a low COD and BOD, which is neutralized to a pH of 8.5 to 9.0.

摘要： An integrated method for purifying industrial and/or urban effluents containing a large amount of organic material in solution and/or suspension, wherein said effluents are treated in a wet oxidation reactor. The effluents are oxidized in the presence of at least one oxidizing gas to mineralize a large part of the organic material therein by producing a gas phase and an essentially liquid phase mainly containing soluble residual organic material, as well as an essentially inorganic solid phase in suspension. The essentially liquid phase from the reactor is subjected to liquid/solid separation to separate the solid phase, and at least a fraction of the separated solid phase is recycled in the wet oxidation reactor. Various alternative embodiments of the method include adding a catalyst and/or an agent for acidifying the recycled solid phase fraction. The facility may operate continuously or semi-continuously between interruptions.

摘要： 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.

摘要： An oxidation catalysts/cocatalyst composition of matter is useful in oxidizing organic waste material. Use of the oxidation catalysts/cocatalyst composition causes the reaction rate to increase and causes the energy required for the reaction to decrease. A solution, including the oxidation catalysts/cocatalyst composition, and a reaction medium composition further including organic waste material are also described.

摘要： A method and apparatus for effecting accelerated chemical reactions at elevated temperatures and pressures including wet oxidation of materials in waste streams. An influent waste stream or first reactant is directed through a long tubular coil within a containment vessel with a second reactant being added to the influent. The waste stream includes gas and liquid components. The flow rates for the reactants of the waste stream are set to cause plug or slug flow of the waste stream through the tubular coil. The curvature of the coil tends to induce a secondary flow in the liquid component such that the liquid component tends to travel in a spiral thereby providing more intimate mixing of the reactants. The containment vessel may be partitioned to form a series of successive compartments to permit different temperature gradients to be applied to successive sections of the tubing coil across its length. Alternatively, a tube in tube construction for the tubular coil permits counter current heat exchange between the waste stream within the inner tube and a returning stream. Multiple injection and extraction points are provided along the path of the tubular coil to permit gas, liquid or solid reactants to be added or extracted as desired. The tubular coil provides an excellent environmental container for the reaction stream and is extremely suitable for temperature control to permit continuous heat input, autogenic operation and continuous heat extraction.
