The hydrodynamics of the ADV trays and F1 valve trays were experimentally studied with an air water system in a φ 600mm circular column.Critical gas velocity through valve holes,pressure,entrainment and weeping were measured.The plate efficiency of the ADV trays and F1 valve trays were determined using air water O 2 system.The experimental results showed that the ADV trays possessed better characteristics than F1 valve trays on the hydrodynamics and mass transfer.The hydrodynamic experimental data of the ADV trays have been correlated and the models of critical gas velocity through valve holes,pressure drop,entrainment and gas velocity through valve holes at weeping point have been obtained,which can be used to design the ADV trays.The paper introduces industrial application on ADV trays.
