A large scale evaporation unit consisting of evaporator, cyclone, and packed tower was constructed, with which studies were made of the liquid entrainment and its removal. The results obtained are as follows: (1) the decontamination factor of the evaporator lies between 10/sup 4/ and 10/sup 5/; (2) that of the cyclone is in the range of 10 to 10/sup 2/; (3) the over-all decontamination factor of the evaporation unit lies between 10/sup 6/ and 10/sup 7/; (4) the optimum vapor mass velocity in the vapor space of the evaporator is about 2000 kg/m/sup 2/hr. With this optimum vapor mass velocity, the maximum over-all decontamination factor is obtained. The results obtained by the large scale evaporation unit were compared with that obtained by the small scale evaporation unit. (auth)
