Granted: 1997-12-27
Abstract: FIELD: chemical technology, inorganic chemistry. SUBSTANCE: invention relates to nickel sulfate production from the spent sulfate electrolytes of refined copper production. Method involves the combined evaporation-crystallization of decoppering solution after copper electrorefining at ratio Fe:Cu = (1.5-3.0):1, under vacuum 1.96-9.81 kPa, dissolving nickel sulfate in mixture of return mother liquor and condensate taken at ratio = 1: (2-4), carbonization of heated nickel sulfate solution with calcium carbonate to pH = 4.5-6.5 by bubbling suspension with compressed air at 70-80 C in mixture followed by carbonate precipitate filtering off. Then the purified filtrate is fed to the repeated combined evaporation-crystallization under the same vacuum value and continuous circulation of suspension up to solid: liquid = 1: (2.5-4.0) and recrystallization of the removed nickel sulfate suspension at stirring, at 40-45 C. Method ensures to obtain large-crystalline nickel sulfate hexahydrate of $$$-modification. Extraction of nickel to crystalline product is increased up to 50-56%, total yield of nickel in salt - 86-90%. Phase composition and an average crystal diameter 0.9-1.2 mm provide retention of friability of nickel sulfate for above 1 year. EFFECT: improved method of isolation. 3 cl, 1 tbl

Granted: 1998-11-20
Abstract: FIELD: oil-producing industry; applicable for increasing oil recovery from producing formations in oil production by the method of replacement. SUBSTANCE: to increase oil recovery, placed on the bottom of injection well is hydrodynamic radiator of elastic vibrations. Injected into well is water (without activators and special heating) required for replacement of oil in producing formation and maintenance of pressure. One part of water flow energy when passing the hydrodynamic radiator, is converted in elastic vibrations within frequency range from 1 to 45 kHz which act on oil reservoir. In so doing, decolmatation takes place in bottom-hole zone of injection well to free capillary-replaced oil and to disturb the dynamic equilibrium on water-oil interface that leads to straightening front of oil replacement with water and to increase oil recovery from producing formation by 10-90%. In this event, treatment of producing formation is carried out without shut-in of well operation, ceasing of oil production, and during the entire term of well operation; and energy of action on producing formation and, consequently, oil recovery are increased with the help of installation of hydrodynamic radiator in all injection wells. EFFECT: higher oil recovery. 2 cl
