Description
In solvent extraction for nuclear fuel reprocessing, a stable emulsion called crud is formed at the interface between the organic and aqueous phases. Crud is an emulsion stabilized by finely dispersed solids. Process disturbances are often induced by crud. Accordingly, crud should be eliminated from the interface in the extractors. The eliminated crud is stable and highly radioactive; thus, the treatment of this crud may be difficult. Complexes of zirconium and tributyl phosphate (TBP) degradation products, such as phosphoric acid (H3PO4) and mono-n-butyl phosphate (H2MBP), are one source of the fine particles that stabilize emulsions in the extraction process. In this paper a chemical treatment method to demulsify crud stabilized by precipitates of Zr-H3PO4 and Zr-H2MBP is studied
