Investigation of hydrodynamic parameters of pulse column under operation with irradiated extractant

Holdup and carry-over of dispersed phase in a pulse column with the KRIMZ packing were investigated with the use of γ-irradiated extractant (30% solution of TBP in n-paraffins). It was ascertained that holdup and carry-over of dispersed phase depend on the dose absorbed over the whole range studied, however, the most considerable changes are pronounced at the doses of 210-290 kGy and higher. It is pointed out that carbonate regeneration of the extractant for the case of intensive mode permits to improve hydrodynamic parameters, but it can not avert gradual accumulation in the extractant of decomposition products of TBP and diluent
