A Glass Still for the Evaluation of Column Packing With Uranium Hexafluoride

Description: The operating holdup and flooding rates of uranium hexafluoride, n-heptane, and perfluorodimethylcyclohexane have been studied in a glass still filled with 1/8 inch nickel Heli-Pak. The flooding rates of the latter two substances are 46.0 and 48.0 cc./min. respectively and the flooding rate for uranium hexafluoride, calculated from the Bertetti equation, is 42.9 cc./min. The operating holdups for these three substances on Heli-Pak were measured at several throughput rates up to the flooding rate and an equation derived, based on the method of Jesser and Elgin, for computing the holdup of uranium hexafluoride from a knowledge of the holdup of perfluorodimethylcyclohexane. Observations of the performance of the packing and a measurement of the number of drops of uranium hexafluoride per milliliter at 75 deg C. are also presented.

Uranium Hexafluoride Purification

Description: An experimental batch distillation column was used to purify UF/sub 6/ containing metal impurities. The degree of purification was determined by comparing the spectrographic analyses of the UF/sub 6/ distillate material with the original feed or pot material. Results are tabulated at 95% confidence limits. (auth)
