DESALTING COLUMN FOR CONDENSATE

摘要

PURPOSE:To decrease considerably the radiation dose rate of a plant by optimizing the relation among the amt. of the treating water for condensate in a desalting column for condensate, the operating conditions such as the grain size of resin thereof and the performance for iron removal. CONSTITUTION:90% iron removal rate can be obtained by decreasing the grain size of resin if the amt. of treating water is small in the relation between the grain size of resin and the iron removal rate when condensate is treated in a mixed bed type resin column. The surface area load of the resin is maintained at <=0.02m<3>/m<2>.h to obtain 90% target iron removal rate in the relation between the surface area load of the resin and the iron removal rate. Therefore, the amt. of the treating water and the grain size of the resin are so selected that the surface area load of the resin attains <=0.02m<3>/m<2>.h.
