Book excerpt: A stagewise approach was used in a theoretical analysis of pulse columns. In the analysis the column was arbitrarily divided into discrete stages comprising that part of the column between two adjacent perforated plates. The operation of the pulse column was described mathematically using material balance equations, and a design method was derived which used two stage lines and two operating lines, one set for the pulse generator upstroke and one set for the downstroke. Assuming equilibrium contact, the effect of recycle in a pulse column was shown to cause a large decrease in the separation obtained as the pulse frequency was increased. Hold-up studies were made using isoamyl alcohol- water, and methyl isobutyl ketone water. The hold-up per cycle of the dispersed phase for both systems was found to be equal to the interstage flow per cycle of the dispersed phase. Hold-up behavior at high frequencies was different for the two systems. Extraction runs were also made using the system methyl isobutyl ketone - acetic acid-water. The effects of recycle were found to result in a drop in column separation efficiency with increased pulse frequency. It was found to be theoretically possible for a column to operate in a pinched-in region even though this is not apparert from an examination of the superficial flow ratio of the two streams being fed to the column Techniques for sampling interstage flow streams in a colurm operating in the mixer-settler region are described.

Book excerpt: A countercurrent extraction column is described which employs timed solenoid valves and pressurized feeds to provide a pulsing action to disperse the phases. The steps in the pulsing cycle are independent and thus provide greater separation of the operating variables than is possible with conventional pulse columns. The column described is particularly useful as a resesrch tool for the study of extraction mechanism although a larger installation operating on the same principles should be quite workable. The 4-stage-cycle or mixersettler type column operation has an inherent advantage in that the rapid coalescence and redispersion of phases are believed to lead to greater extraction than simple movement of a dispersed phase through a continuous medium. In addition, the sharp pulse provided should produce greater turbulence than the more conventional pulsing arrangement. Some results of operation on the extraction and stripping of uranyl nitrate using tributyl phosphate as a solvent are included. These data correspond to Metal Recovery and Erex type systems. (auth).

Book excerpt: Information on the development of pulse columns for the Purex Process is presented in order to indicate qualitutively the performance attainable with improved cartridge designs, and to show some of the factors involved in scaling up pilot plant results to full plant scale. The pulse columns were designed to produce separated uranium and plutonium products decontaminated by at least a factor of 10>s7/sup /om fission products, with average uranium and plutonium losses of less than 0.2% per column and an overall yield of at least 99% of each product. The five types of behavior observed in pulse columns as a function of throughout rate and pulsing conditions are described. The effects of increasing frequency and throughput rate on pulse column efficiency are shown. The different types of perforated plates and packings investigated for Purex service are discussed. Short cuts, indicated by Purex development studies, that may be taken to provide a suituble column design with a minimum of pilot plant development are described. (M.C.G.).
