Abstract
Carbonation and phosphatation processes have been now in use for several decades for production of refined sugar with each process having its supporters. In the last decade, changes in the raw sugar quality parameter considerations about cost of energy and environmental constraints have changed the refining landscape. The authors have examined the selection of the most appropriate process on the basis of capital and operating cost, process capability and environment concerns.
Here, the advantages and disadvantages of each process are reviewed. Besides description of primary decolourization cum clarification process, i.e. carbonation and phosphatation, the process of secondary decolourization through various modes has been discussed. Recommendations to streamline and simplify the sugar refining using the best available process are presented with a hope for sugar refining industry to survive and prosper under given situation.
