Direct method of nitric acid-potassium chloride can produce potassium nitrate for molten salt at low cost.The se-paration of nitric acid/hydrochloric acid from a solution containing chloride salts by solvent extraction is one of the key steps.The hydraulic performance of the pulsed sieve plate extraction column in the treatment of H+/K+/Cl-/H2O-tributyl phosphate/sulfonated kerosene system was studied.The results showed that the diameter of the dispersed phase drops decreased with the increase of the pulse intensity,and the superficial velocity of the two phases had almost no effect on it.The holdup firstly decreased and then increased with the increase of the pulse intensity,and increased with the increase of the superficial velocity of the two phases.According to the experimental data,Kumar-Hartland correlations of drop diameter and holdup were fitted,and the average absolute relative deviation（AARD） was 4.74% and 5.60%,respectively.
