Preferred Abstract (Original): 

Hydrodynamic parameters were measured in a Nutter valve tray simulation column. The clear liquid height was determined in different operating regimes (foam + mixed and spray regimes) and new formulas were developed as functions of weir height and flow parameter.
New correlations were developed, as functions of geometrical and operating parameters, for the total liquid hold-up and the relative froth density.
