Evaluation of the Neltec Colour Q for measuring the purity of magma from C centrifugals : final report 2018/201

Abstract

In Australian factories one operator typically manages the high grade fugalling, sugar drying and low grade (C) fugalling stations. The C fugals are managed least effectively as there is no process instrumentation to monitor on line C sugar purity or final molasses purity. Conditions can change rapidly in the C fugals without the operator being aware and poor performance can persist for several hours. Tight control of the C sugar purity is important to avoid high sucrose losses to final molasses or an excessive recycle of impurities in the C sugar (magma or remelt) to the pan stage.
