Pan/fugal station modelling for planning factory upgrades

Models to predict the mass flow rates and composition of the different process streams for the pan and fugal stations in Australian raw sugar factories have been developed. The models incorporate several options for the three massecuite boiling scheme that is used universally by Australian mills to produce shipment sugar from the two high purity massecuite streams. The basis of the models and their application to planning factory upgrades are discussed. The influence of cane conditions (sugar and impurity contel1l) and pan stage exhaustion performance are considered.
