---SUMMARYThe interest of chromatography of beet molasses to increase the sugar yieldin a beet sugar factory, when there is a significant difference between theprice of crystal sugar and molasses is well known.The Authors demonstrate the importance of a better integration to the. process, when a new sugar factory is built: it becomes very advantageous tofeed the chromatographic separator for the recovery of sugar with thesecond mother liquor (low green syrup). In this case, it is no longernecessary to invest in a third strike of crystallization, and it is possible tobetter use the equipment out of the season.ASSBT Meeting Palm SpringsMarch 02 to March 05, 2005 .149
I.CHROMATOGRAPHIC SEPARATION IN THE BEET SUGAR INDUSTRYBeet sugar factories are still being built with the conventional "three strikes"crystallization design:Table 1: Block diagram of the conventionalbeet sugar factory PulpsIIRaw juiceIIPurificationIICarbonatationmudThin juiceThick juiceSugarIIAll the sugar recovered is extracted and purified from the thick juice by crystallizationonly. The molasses is the ultimate by-product of this process, the last mother-liquor ofthree successive crystallization steps. Having a purity of 58-60, it cannot be crystallizedanymore, although it still contains approximately 11 to 16 % of the sugar initially presentin the beet:Table 2: Sugar balance in a conventional beet sugar factory% beetSugar in beet17.5Loss at diffusion0.250.06Loss at purificationLoss in molasses2 - 2.95Undetermined loss0.3Sugar produced13.94 - 14.89Overall yield of extraction: 79.7 - 85 %Sugar lost in molasses: 11.4 - 16.8 %ASSBT Meeting Palin SpringsMarch 02 to March 05, 2005:150
Since the development of the chromatographic separation. it has become possible todesugarize the molasses by means of a complementary technology. which "step-in"where crystallization cannot be efficient anymore:Table 3 : Beet sugar factory with thin juice delimingand molasses desugarization·L - - - - - - - - . - - - - I 1 - - - -. 11PulpsIIRaw juiceIIPurificationCarbonatationmudsIHard thin juiceI ':- DEtIMING J.

The chromatographic separation of molasses allows typically recovering 90 % of thesugar in molasses, thus increasing the sugar recovery significantly:Table 4: Sugar balance with a molasses desugarization plant% beet17:5Sugar in beetLoss at diffusion0.25Loss at purification0.06Loss in rafinate0.2 - 0.29Loss in secondary molasses0.3 - 0.4Undetermined loss0.3Sugar produced16.2 - 16.69Overall yield of extraction: 92.5 - 95.4Additional sugar produced: 10.4 -12.8 % on sugar in beetCompared to the conventional "all crystallization" process, this represents anadditional recovery of 10.4 -12.8 % on sugar in beet.In view of this sizable improvement, many plants of molasses desugarization havebeen added to existing beet sugar factories, where the economic conditions justifiedthis supplementary sugar extraction. (1) (2) (3)II.INTEGRATING THE CHROMATOGRAPHIC SEPARATION TO THE BEETSUGAR PROCESSThe success of a new technology is often ensured by its degree of integration in theoverall process, thus generating more or less profits to the end-users.A typical example of this assessment can be found in the development of deliming, anion-eXChange technology that has developed over the years in the beet sugarprocessing.Initially used for thin juice decalcification in order to improve the evaporatorsefficiency, it was generating inconvenient salty effluents until elegant and integratedprocesses such as the Gryllus process or the NRS process made it completely"effluent free" and well adapted to the beet sugar plant.The NRS deliming process (4) has also the advantage of producing soft molasses,suitable to the chromatographic separation process. Therefore, integrating a "NRS"juice deliming system in a beet sugar factory will avoid the end-user to have to add inmolasses pre-treatment a costly chemical softening system prior to the molassesseparator. The ultimate integration of deliming is the use of raffinate from theseparator for the regeneration of the deliming system (Patented Applexion/LSU.Process), thus making the process also "chemical free".

Facing a very competitive cane sugar industry and the challenge from the corn andwheat sweeteners, the modem beet sugar industry will pursue its efforts ofmodernization in the following directions: Increasing the sugar extraction by means of chromatographic separation Increasing the duration of equipment operations during the year Balancing better the use of crystallization versus chromatographic separation:By means of a low green syrup separator, it is possible to decrease the size ofthe sugar boiling house and to keep the crystallization equipment where it isworking the best: for the first strike and the second strike of the sugar plant.

Sugar is produced from both sugar cane and sugar beet. When taking a look at a rough classification into process steps, the applied production processes seem to be quite similar. General observations, on the other hand, only show little common ground between beet sugar factories and cane sugar factories.
