| Abstract: | The property of organic solvent extracting WPA in the reciprocating sieve plate column is researched. And the influence of the structure parameters and operation conditions of vibrated orifice column on the extracted fraction of phosphoric acid is analyzed. The results show that the WPA extracted fraction of 84% is obtained at the free area rate of tray of 53%,tray spacing of 7 cm, and vibrating frequency of 150 r/min. So the qualified industrial phosphoric acid is gained by further washing and stripping sections. |
