    摘要: In a supercritical oxidation process, the oxidized supercritical fluid effluent (46) discharged from the upper region of the reactor vessel (10) is contacted with a cold quench liquid (66) so as to produce a relatively solids free vapor stream (53) and a liquid stream (51) containing the bulk of the precipitates and other solids carried over in the oxidized supercritical fluid effluent (46). The temperature of the resultant liquid stream (51) is maintained at a temperature below the solids solubility inversion temperature, typically below 600.degree. F., so as to dissolve a substantial portion of the precipitates and other solids collected therein.

    摘要: Disclosed is a method of substantially completely oxidizing material in an aqueous phase at supercritical temperatures and sub- or supercritical pressures by initiating the oxidation in the presence of small amounts of strong oxidizing agents that function to increase the initial reaction rate for the oxidation. The strong oxidizing agents suitable for use in the present invention comprise at least one selected from the group consisting of ozone (O.sub.3), hydrogen peroxide (H.sub.2 O.sub.2), salts containing persulfate (S.sub.2 O.sub.8.sup.2-), salts containing permanganate (MnO.sub.4.sup.-), nitric acid (HNO.sub.3), salts containing nitrate (NO.sub.3.sup.-), oxyacids of chlorine and their corresponding salts, hypochlorous acid (HOCl), salts containing hypochlorite (OCl.sup.-), chlorous acid (HOClO), salts containing chlorite (ClO.sub.2.sup.-), chloric acid (HOClO.sub.2), salts containing chlorate (ClO.sub.3.sup.), perchloric acid (HOClO.sub.3), and salts containing perchlorate (ClO.sub.4.sup.-).

    摘要: A method of continuous flow hydrothermal oxidation which provides for a low cost means of reaction initiation and propagation. The aqueous-organic feedstock and oxidant are introduced to a small reaction chamber and allowed to mix with the hot, partially reacted contents thereof. This backmixing serves to initiate the reaction of the incoming feedstock. Optionally, the contents of the chamber then pass to a second reactor located downstream, in order to allow for completion of the oxidation reaction.

    摘要: The present invention relates to a novel aqueous-phase oxidizer and solids separator reactor. More particularly, the invention relates to a two zone pressure vessel in which precipitates and other solids fall or are sprayed from a supercritical temperature super zone into a lower temperature sub zone. The feed material may consist of various waste products which are subsequently oxidized in the super zone of the pressure vessel. The resultant brine or slurry which is found at the lower temperature sub zone of the vessel is removed via a pipe and disposed of accordingly.
