Abstract
Abstract THE PROCESS FOR PRECIPITATING A SACCHAROSE-LIME COMBINATION FROM SUGAR FACTORY MOLASSES BY ADDING LIME TO MOLASSES UNDER COLD CONDITIONS IS IMPROVED BY RECYCLING SEVERAL VOLUMES OF LIME TREATED MOLASSES PRIOR TO THE SEPARATION OF THE SACCHAROSE-LIME COMBINATION WITH ONE VOLUME OF UNTREATED DILUTED MOLASSES. THE RECYCLED MIXTURE OF LIME TREATED AND UNTREATED DILUTE MOLASSES IS PASSED COUNTERCURRENT TO THE DIRECTION OF LIME ADDITION SO THAT THE RECYCLED MIXTURE ENCOUNTERS AN INCREASING ALKALINE GRADIENT. THE BENEFITS OF THIS PROCESS INCLUDE IMPROVED FILTERABILITY OF THE LIME-SACCHAROSE COMBINATION AS WELL AS IMPROVED STABILITY OF THIS COMBINATION.
