| Popis: | The gas behaviour was studied in a gas-liquid reactor stirred with multiple turbines. Triple PBTs pumping either down or up and BT-6's were used. The behaviour of coalescing (water) and non-coalescing (sodium sulphate solution) systems was investigated. The gas phase behaviour was characterised by means of the RTD and modelled with the axial dispersion model. This last was confirmed to interpret the experimental data well for water and satisfactorily for the coalescence-inhibiting solutions. The influence of the operating conditions, turbine type and system coalescing behaviour on the model parameter is discussed. Comparison is also made with similar data regarding Rushton turbines and high-solidity ratio hydrofoils as well as gas hold-up. |
