    摘要: An improved method and apparatus for effecting a substantial reduction in retention time of oxidation processes by the autoclave oxidation of ion species dissolved in aqueous solutions. In one embodiment, the invention provides for oxidation of dissolved reduced ion species including ferrous iron (Fe.sup.+2), uranium (U.sup.+4) and vanadium (V.sup.+3) from wet process phosphoric acids, or for conditioning of aqueous solutions for other uses, such as corrosion control, by raising the valence state of dissolved ion species. In accordance with the present invention, pure oxygen, present in quantity of at least 94% by volume, is utilized as an oxidizing agent with specified process parameters: temperature, pressure and mixing conditions in an autoclave reaction vessel. In a presently preferred embodiment, the following specified parameters have achieved optimum results with regard to a significant decrease of retention time of the aqueous solution treated in the autoclave vessel: temperature range of from about 120.degree. F. to about 160.degree. F., pressure range of from about 120 psi to about 150 psi and effecting agitation by the use of an impeller located near the interface of the liquid and gas mixture in the vessel to provide a dispersion of the liquid solution in the gaseous phase. In accordance with such embodiment, a reduction of retention time for oxidation of uranium (U.sup.+4 .fwdarw.U.sup.+6) and vandanium (V.sup.+3 .fwdarw.V.sup.+4) metals from wet process phosphoric acid has been found to be less than two minutes, whereas, prior processes for effecting the same oxidation results have taken at least one hour.

    摘要: Methods for control of excessive corrosion in wet process phosphoric circuits are effected by oxidation of reduced ion species in the acid with maintenance of EMF value of the acid above about 190 millivolts (S.C.E. reference) through the digestion circuit. Supplementary monitoring is by a ceric red-ox titration procedure. In one embodied form, the present invention is utilized to control corrosion in a phosphoric acid plant digestion system (and subsequent processing equipment) operating by a dihydrate (gypsum) process even when such a process employs a calcined western U.S. phosphate ore feed from a relatively highly carbonaceous ore. The invention is also applicable for treating wet process phosphoric acid in phosphoric acid plants having a digester system operating by a hemihydrate process. In a presently preferred embodiment, additions of manganese dioxide to a primary digester in a sufficient amount effective to achieve an EMF value over about 190 millivolts will significantly control the occurrence of excessive corrosion in phosphoric acid circuits. In yet another preferred embodiment, an oxygen autoclave oxidation is used to oxidize the reduced ion species present in the acid to inhibit corrosion.
