Optimizing Carbonatation in Sugar Refining by nghi is a document available to read on EtoBox.

This document summarizes the carbonatation process used at Tongaat Hulett Refinery to clarify and decolorize very high polarity sugar melts. The key steps are: 1) Slaked lime is added to the sugar melt at 0.5-0.65% and gassed in three saturators - 80% of gassing occurs in the first saturator to pH 9.0-9.5, with the remaining gassing in the second saturator to pH 8.3. 2) The saturated melt is heated to 83C in a third saturator before filtration. 3) Calcium carbonate slurry is separated from the melt usi
