In the nickel and cobalt production plant located in Punta-Gorda Cuba, an effluent liquor is obtained with several pollutants species of Ni(II)–NH3–CO2–SO2–H2O system. previous studies performance electrocoagulation (EC) for removal from this was demonstrated on a lab-scale bench-scale. research, geometric, electrical equilibrium parameters used as criteria scaling-up EC process were evaluated through hydrodynamic, kinetic operating cost analysis. For purpose, four semi-continuous...
The nickel removing by electrocoagulation of Ni(II)-NH3-CO2-SO2-H2O system was studied in a batch reactor 50 L useful volume, with stirring, and two pairs aluminum electrodes. operating parameters were concentration between 255 342 mg L-1, current density 11.0 16.6 mA cm-2, pH 8.34±0.06, mean temperature 58.4±3.9 oC retention time min. maximum removal 99.7 % at specific energy consumption 16.86 kWh kg-1 Al3+, 2.438 Ni the adsorption capacity 5819 g-1 Al3+. precipitate contained 37.2 true...
Se identificaron los factores que inciden en el incremento de la concentración del níquel disuelto suspensión carbonato básico níquel, tecnología lixiviación amoniacal. propuso un modelo estadístico para determinar función factores: amoníaco, dióxido carbono y azufre solución alimenta a las columnas destilación, pH suspensión. El se validó con antecedentes experimentales una serie ecuaciones equilibrio termodinámico sistema Ni (II)-NH3-CO32--S2O32--SO42--H2O. obtuvo mayor relación Ni/S...
This work presents the results obtained in carrying out mass and energy balances calcining kiln of company commander Ernesto Che Guevara, for determining consumption index petroleum used obtaining nickel oxide through thermal decomposition basic carbonate. It was shown that a production carbonate 12 t / h with 69% moisture, it is necessary to feed about 1100 kg fuel, an 91.67 fuel per ton load.
