Comparison of Dow Corning 544 antifoam to IIT747 antifoam in the 1/240 SRAT

PDF Version Also Available for Download.

Description

The Defense Waste Processing Facility requested that the Immobilization Technology Section compare the relative foaming tendencies of sludge simulant during simulated Chemical Processing Cell operations (HLW-DWPF-TTR-99-0012). Dow Corning 544 antifoam, currently used in DWPF, was compared to a new antifoam formulation developed at the Illinois Institute of Technology. A task plan was written and approved. The task plan deliverables included a recommendation on the choice of antifoam, an evaluation of the influence of solids concentration on foaming, an evaluation on the effect of boil-up rate on foaming, an estimate of the mass of steam stripped to remove 90 percent of ... continued below

Dow Corning 544 antifoam, currently used in DWPF, was compared to a new antifoam formulation developed at the Illinois Institute of Technology. A task plan was written and approved. The task plan deliverables included a recommendation on the choice of antifoam, an evaluation of the influence of solids concentration on foaming, an evaluation on the effect of boil-up rate on foaming, an estimate of the mass of steam stripped to remove 90 percent of the mercury, and a determination of the fate of mercury. Additional parameters to be investigated during experimentation included the maximum foam height observed, hydrogen generation rates, and nitrite destruction rates.
