Gas-liquid distribution in the froth zone on cross-flow trays – Raw data

For the purpose of investigating the phase distribution on different cross-flow trays, experiments were carried out using a 1.2 m diameter tray column test rig at the Technical University of Munich. The experimental facility was operated with a mixture of tap and deionized water as liquid phase and air as gas phase. The phase distribution in the froth zone was measured by a conductivity sensor matrix developed and manufactured at the Helmholtz-Zentrum Dresden-Rossendorf. Several operational points were investigated by variation of liquid flow rate and gas load. The present data publication contains raw data of these measurements along with descriptions of the experimental setup, the data acquisition and the data organization.
