SuperLig Ion Exchange Resin Swelling and Buoyancy Study

Intermediate-Scale Ion Exchange Removal of Cesium and Technetium from Hanford Tank 241-AN-102

“…The bulk resin density for batch #980624001DC was reported by SRTC to be 0.489 g/mL. 8 The TcO Previous Re batch contact tests with SuperLig ® 639 indicate that batch #990420DHC720067 has a 31% higher capacity than batch 981015DHC720011 at comparable final Re concentrations. 16 Based on this data the 50% TcO 4 -breakthrough would be expected to occur after >196 BV of feed have been processed.…”

Small Column Ion Exchange Testing of Superlig 644 for Removal of 137Cs from Hanford Tank Waste Envelope A (Tank 241-AW-101)

“…The SL-644 resin is known to change in volume as a fimction of the solution pH and ionic strength (Hassan et al, 1999). The variation in bed volume as a fimction of the process steps for both columns is shown in Figur& 3.5 and 3.6 as a ratio of bed volume to the baseline value of 15 mL.…”

“…The Battelie values at room temperature and at 85°C are duplicated from Kurath, et al, 1999, while all of the SRTC data is reproduced from (Hassan, et al, 1999). The F factor is the ratio of the dry mass of exchanger to the initial mass of the exchanger.…”

“…The dry bulk densities were obtained by multiplying the as-received bulk density by the appropriate f factor. A particle density of 1.611 g/mL was reported by Hassan, et al, 1999. Battelle SRTC As-received bulk density (room 0.86 #mL 0.88 temperature) Dry as received bulk density (85"C) 0.78 g/mL Dry as received bulk density (95°C) 0.69 g/mL 0.793 g/mL F factor I@85°C (% water) 0.907 (9.3%) F factor@ 95°C (% water) 0.80 (20VO) 0.9 (1OYO)…”

“…The data are not precise enough to allow an accurate estimate of the average particle diameter but the average apparently lies between 210 and 425 microns with a rough estimate of 330 microns. The SL-644 resin and bed preparation was performed using a procedure similar to that recommended by Hassan et al 1999, with the exception that the solution volumes and flow rates were larger. Prior to packing the resin bed, two 7.9 g batches of the as-received SL-644 resin were placed in separate beakers.…”
