Extraction Test in a Pulse Column Using a Slurry Feed Containing 20% Solids

Integrated Process Design Report on Feed Materials Production Center, Fernald, Ohio Refinery and Green Salt Plant

“…All runs were made in a 2 inch diameter piulse column. The initial experiments were carried out on the scnibbing axid reextraction operations (26,27). The results were satisfactory.…”

“…Other scrubbing agents were studied at MCW to determine whether they would give a higher product purity than, deionized water 7 There is evidence (26,27) to indicate that this througl^jut can be achieved at roan taiqperature. If 985 gal/(hr, )(sq,ft,) is not attainable^ a higher temperature will be required.…”

“…Pulse conditions and plate details; The effect of amplitude, frequency, volume throughput and wave form have not been established for scrubbing. The only pulse column runs made to date were in the 2-inch diameter column at OENL (26,27). These runs were all of relatively short duration and the purity data were inconclusive.…”
