MIXER-SETTLER DEVELOPMENT--OPERATING CHARACTERISTICS OF A LARGE-SCALE MIXER- SETTLER
Technical Report
·
OSTI ID:4105347
A pump-mix mixer-settler was demonstrated to have an over-all efficiency greater than 90% for the extraction of UO/sub 2/(NO/sub 3/)/sub 2/ from TBP at total flow rates up to 45 gpm. Phase separation was satisfactory at 45 gpm, at which flow rate the residence time in the settlers was 11/2 min. It appeared possible that a throughput approaching 60 gpm would be operable although at an over-all efficiency of less than 90%. The tests were made on a three-stage unit, but the data can be extrapolated to multistage units. The effects of design of the impeller and mixing section, impeller speed, flow rates and ratios, and operating temperatures were studied. The mechanical performance and dependability of the unit were excellent. (auth)
