Abstract
L'émulsion comprenant une phase organique, une phase aqueuse et des solides, formée lors de la production de l'acide phosphorique par voie humide, est fractionnée en sa phase organique (104), sa phase aqueuse (F) et ses solides (101) dans une centrifugeuse (31) à panier perforé (103) où la force centrifuge suffit pour chasser la phase aqueuse à travers les solides s'accumulant sur la paroi perforée, mais ne suffit pas pour refouler ainsi la phase organique légère qui est évacuée par un tube d'écrémage (105).
