The multiple upcomer (MU) extraction tray was specifically developed for aromatics extraction processes. Hydro‐dynamic and mass transfer experiments have been carried out with n ‐butanol/succinic acid/water as an experimental system in a MU tray extraction column of 0.1 m diameter. The dispersed phase hold‐up, drop size and overall efficiency were measured and the hydrodynamic and mass transfer parameters were correlated. The flooding velocities and the overall efficiency predicted from the correlation for this column agreed well with the experimental data.
