The numerical model, which predicts the arsenic re-distribution at any point of the single zone pass, multiple molten zone passes, or ultimate distribution, is described for providing simulations. Experimental work on arsenic removal by vertical zone melting process was carried out with prepared phosphoric acid samples as the starting material. The experimentally obtained axial concentration profiles were compared with the theoretical predictions, which proved the efficiency of the proposed model in removing the arsenic concentration significantly. Following the model and as evidenced from the theoretical predictions, the arsenic concentration reduced to ISSN : 0888-5885 En ligne : http://pubs.acs.org/doi/abs/10.1021/ie2027553 [article] Numerical and experimental investigation of arsenic removal process from phosphoric acid by vertical zone melting technique [texte imprimé] / Yongsheng Ren, Auteur ; Xiaoxiao Duan, Auteur ; Baoming Wang, Auteur . - 2012 . - pp. 4035–4040.
