OPTIMIZATION OF FLOTATION PARAMETERS IN DEINKING OF ONP AND OMG

摘要：

The effect of flotation parameters such as flotation consistency, temperature, flotation time, air to pulp ratio, turbulence level (velocity of pulp flow), and pH on ONP/OMG deinking efficiency was studied by using a high-consistency laboratory pulper and a laboratory deinking cell developed by ourselves. The optimized flotation conditions were: flotation consistency 1.2%, 50℃, 6min, air to pulp ratio 50%, velocity of pulp flow 3.5m/s and pH 8.5. By using the optimized pulping and flotation conditions, the deinking pulp brightness could reach 59.15% ISO, 10.18% ISO higher than that of the control, the effective residual ink concentration was 234.65 mg/kg, which less heavily than 875.56 mg/kg of the control, theoretical deinking efficiency was up to 84.42%.
