Popis:	Both batch-wise and semi-continuous Darex flowsheets were developed on a 1.4-liter scale using 61 wt.% nitric actd to volatilize and/or decompose chloride. The 61% acid is favored over higher concentrations for safety and avallability. The batch flowsheet features simplicity and ease of operation; either batch or continuous dissolution can be used. The semi-continuous scheme, which assumes continuous dissolution, offers reduced cycle times bet more complex operation. Both flowsheets accomplish chloride removal to < 350 ppm by adding batch-wise only the amount of nitric acid required for solvent extraction feed adjustment and regeneration of dissolvent. (auth)
