Abstract

Procédé d'épuration d'un sirop de sucre par électrodialyse. Dans une sucrerie le sirop de deuxième jet, avant de parvenir au troisième étage de cristallisation 3, passe dans les cellules de rang pair 12, 14 d'un électrodialyseur 10 classique. Le liquide d'élution, dont il est connu que la conductivité doit être de même ordre de grandeur que celle du liquide à épurer, est constitué, non pas d'eau comme classiquement, mais par une mélasse prélevée en sortie de cuite de troisième jet, à viscosité élevée. Cette viscodité permet d'obtenir la conductivité voulue avec des concentrations en impuretés ionisables beaucoup plus élevées. Applications en sucrerie et raffinerie.Process for purifying a sugar syrup by electrodialysis. In a sugar refinery, the second-jet syrup, before reaching the third crystallization stage 3, passes into the cells of even rank 12, 14 of a conventional electrodialyzer 10. The elution liquid, of which it is known that the conductivity must be of the same order of magnitude as that of the liquid to be purified, consists, not of water as conventionally, but of a molasses taken at the outlet of the third jet firing. , high viscosity. This viscosity makes it possible to obtain the desired conductivity with much higher concentrations of ionizable impurities. Applications in sugar refinery and refinery.
