THE HORIZONTAL AIR-PULSED COLUMNA NEW LIQUID-LIQUID CONTACTOR FOR RADIOACTIVE PROCESSING

Abstract

A new type of horizontal pulsed column is described which has been ; developed recently at A.E.R.E. Harwell. Preliminary work carried out with the ; water --toluene -acetone system has shown the extraction efficiency of the unit ; to be comparable with that of the conventional vertical type of pulsed column. ; The contactor is extremely simple mechanically and it is recommended that further ; development work be carried out in order to optimize the contactor geometry and ; to determine the extraction efficiency of the unit using a uranium system. This ; type of extractor should be considered for future processing applications where ; the headroom is limited and the use of air-pulsed columns is impracticable. ; (auth);
