METHOD OF RECOVERY OF EXTRACTANT ON THE BASE OF TRIBUTHYLPHOSPHATE IN DILUENT Russian patent published in 1994 - IPC

Abstract SU 1630556 A1

FIELD: radio-chemical technology. SUBSTANCE: recovery of irradiated extractant solution in diluent involves rectification with the aid of life saturated water steam. The ratio of flows of life steam and extractant to be recovered is selected such that driving-off of extractant into distillate is provided. An aqueous distillate phase is used as phlegm into which alkaline with concentration of 0.5-0.1 mol/l is introduced to enhanced purification degree of extractant. To obtain life saturated water steam distillate aqueous phase is evaporated, evaporation permitting to conduct the process in evaporated water-wise closed cycle and consequently to prevent distillate aqueous phase discharge. EFFECT: enhanced purification degree of extractant and reduced wastes. 4 cl, 1 dwg, 1 tbl
