The entrainment and the pressure drop were studied in a 30 cm distillation column with three valve trays. Three industrial types of valves were investigated using an air‐water system. The air rate varied from 100 m 3 /h to 800 m 3 /h and the liquid rate from 100 1/h to 1.000 1/h. Four weir heights (4.5, 6.0, 7.5, 9.0 cm) and four plate spacings (30, 37.5, 42.5, 50 cm) were used. Equations for the amount of entrainment and the pressure drop were derived and compared to previous results from the literature.
