Patent ES-404449-A1 (ES)
Title: Process and apparatus for removing liquid from wet or moist particles
IPC: B29B13/06
Filed: 1972-07-01
Abstract: Process and apparatus for removing liquid from wet or moist thermoplastic particles, wherein the material, which may be in granular or powdery form, is introduced into a gas stream which blows it at a high velocity in a substantially tangential direction against a curved wall provided with apertures. The thermoplastic particles repeatedly impinge on and rebounce from the curved wall and as a result the liquid is flung off. The liquid is carried away by the gas stream through the apertures in the curved wall, the thermoplastic particles are separately collected and discharged at the downstream end of the curved wall.

Title: Continuous slurry process for formation of aromatic polycarboxylic acids
IPC: C07C51/41
Filed: 1974-01-03
Abstract: The solid-state disproportionation of potassium benzoate to dipotassium terephthalate and benzene using zinc benzoate catalyst is conducted with the solid reagents dispersed as a slurry in liquid terphenyl diluent. The reactor effluent is water-quenched to obtain a liquid terphenyl phase, a water phase containing dissolved phthalates, and solid spent zinc oxide catalyst. The catalyst is separated by filtration, reslurried in terphenyl, reacted with benzoic acid to regenerate zinc benzoate, and the resultant catalyst slurry recycled to the reactor. The solids-free aqueous phase is contacted with benzoic acid to precipitate terephthalic acid crystals and form soluble potassium benzoate. The crystals are separated by filtration and recovered as a product of the process. The aqueous potassium benzoate solution is concentrated by evaporation and then contacted with hot terphenyl to produce a slurry of solid potassium benzoate in terphenyl for recycle to the reactor. Byproduct benzene is vented from the reactor and/or the effluent quench step.

Title: Recovery of nitric acid soluble transition metals from sulfur and iron containing ores of the same
IPC: C22B15/00
Filed: 1976-04-15
Abstract: The ore is subjected to nitric acid leaching and the leach solution is heated to a temperature at which one of the additional sulfur and iron values is selectively insolubilized with respect to the solution, while the other is maintained in solution for subsequent separation from the liquor after the insolubles have been removed and the liquor has been neutralized. In addition, in one embodiment of the invention the heating and acid neutralization steps are controlled within certain prescribed limits to make it possible to remove the metals from the liquor by solvent extraction without the problem of lasting precipitates forming in the liquor and fouling the extraction process. Where there is a sizable amount of dissolved iron in the liquor, the liquor may be subjected to autoclaving at a temperature above about 149 DEG C (300 DEG F) to precipitate the iron as the oxide thereof. This effect is possible even where the liquor is high in sulfate concentration.
