Recently various trays in which mass transfer operations are carried out have been developed, and the authors have designed one of the rotational-current tray which is designed to direct flow of ascending gas horizontally across the tray surface. In this report, as a fundamental study for mass transfer on this tray, flow mechanism and liquid holdup on the tray are considered experimentally.
Experiments are carried out by water-air, methanol-water air and gricerinewater-air systems.
