    摘要: Phosphoric acid is produced by a wet process in a homogeneous medium from calcium phosphate ore, sulphuric acid and a continuously added aqueous solution of recycled acid.Part of the phosphate is treated in a primary reaction medium, prepared separately and differing in composition from the final medium sought. By regulating the compositions of the various reaction media, the present process advantageously increases the concentration of the phosphoric acid produced and/or enhances the quality of filtration, along with other advantages.The process can advantageously be applied for the economic treatment of low-grade, poorly reactive or unground phosphates.

    摘要: The invention relates to a process for the recovery and the concentration of uranium (VI) contained in an organic phase. The organic phase is treated continuously in a contact zone with an aqueous solution containing an oxidizing-reducing agent in the reduced state, said oxidizing-reducing agent being capable of reducing U.sup.+6 to U.sup.+4 in said aqueous solution. The aqueous solution employed in the process issues in part or in its entirety from the cathodic compartment of an electrolytic separation cell, which is under a direct current potential, and the aqueous phase issuing from the contact zone feeds in part or in its entirety the anodic compartment of the electrolytic cell. The process is of particular interest when applied to the recovery and concentration of uranium contained in a wet process phosphoric acid.

    摘要: Intimate and efficient contacting of plural, physically disparate phases, e.g., a gas and a liquid, is achieved by contacting the phases cocurrently in a column. The gas phase is introduced at a velocity between its phase transition inversion point (T) and multiple critical point (M.sub.c) velocities, which velocity is sufficient to create a dispersion of the second phase, i.e., the liquid phase, in the gas and thereby establish at most the following zones, from bottom to top, in the column: a bottom zone of constant liquid concentration designated the emulsion zone, a zone of decreasing liquid concentration, and a zone of constant liquid concentration wherein the liquid exists in the form of droplets. The feed velocity of the liquid is adjusted accordingly to provide a mass liquid concentration value in the emulsion that is between the mass liquid concentration value transition inversion point and multiple critical point values.

    摘要: Water soluble polymeric flocculants are prepared by photopolymerizing olefinically unsaturated hydrophilic monomer(s), the photopolymerization recipe including a polyhydroxylated organic additive, such as gluconic acid. Such polyhydroxy compound facilitates solubilization of the resultant flocculants, without substantial decrease in the molecular weight thereof, and ensures against the by-production of water insoluble fractions.
