Sludge Batch 4 Simulant Flowsheet Studies with ARP and MCU: Impact of MCU Organics

Paper Study Evaluations of the Introduction of Small Column Ion Exchange Waste Streams to the Defense Waste Processing Facility

“…19 Experimental testing would be required to evaluate the impact of using CST that has been ground in a prototypical manner. This evaluation, along with simulant testing, 22 demonstrated that the CPC process could accommodate the MST stream. The MST component of the SCIX is expected to be similar to the MST from the ARP process, and no issues are expected during processing.…”

Sludge Batch 4 Without Tank 4 Simulant Flowsheet Studies: Phase I SRAT Results

“…The flowsheet runs provide an evaluation of potential chemical processing issues, quantification of the potential hydrogen generation rates, and estimation of the required acid stoichiometry for the sludge. A Task Technical & Quality Assurance Plan (Baich 2004) was issued outlining the activities and controls necessary to meet the objectives and requirements of the TTR. The studies documented in this report, as well as the flowsheet testing previously performed and documented with the SB4 compositions containing Tank 4 (see Baich et al 2005), are considered as part of Phase I testing.…”

Impact of the next generation solvent on DWPF CPC processing

“…Experiments conducted in 2005 utilized a MCU solvent comprised of 0.007 M BobCalixC6, 0.75 M Cs-7SB, and 0.003 M TOA in the diluent Isopar  L (69.14 wt%) [3]. This solvent was tested in simulated SRAT cycles at a concentration of 500 ppm (mg solvent/kg strip effluent).…”
