Abstract
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 104 and 105. (2) That of the cyclone is in the range of 10 to 102. (3) The over-all decontamination factor of evaporation unit lies between 106 and 107. (4) The optimum vapor mass velocity in the vapor space of the evaporator is about 2000kg/m2hr. With this optimum vapor mass velocity, the maximum over-all decontamination factor is obtained. Furthermore, the results obtained by the large scale evaporation unit were compared with that obtained by the small scale evaporation unit.Keywords
