• Studies were made of the de-entrainment efficiency of an 8Omm-diameter sieve plate column for the steam-water system. Variables studied were superficial steam velocities from 22.2 to III cm/sec, reflux ratios from O. I to 3.O and plate spacing from IO to 4Ocm. It was found that some of the droplets formed on the n-th tray and carried up through the n+l-th tray at a ratio f1 were carried up again through the n+2-th tray at a considerably greater ratio f2, and some of these droplets carried up through the two trays were carried up again and again through the n + 3-th tray at a slightly greater ratio f3 than f2, which seriously impaired the efficiency of the plate column. The maximum values of decontamination factors DF1, DF2, and DF3 obtained were nearly lO2, lO3 and lO4 respectively.
