Solids Control in recovery boilers in the Pulp and Paper Industry. Lowering production costs The Neltec ColourQ automatic colorimeter has been specifically developed to monitor sugar quality and enable you to respond immediately to process variations in pans and centrifugals, eliminating the need for wide safety margins, while preventing sugar outside specifications from reaching the drier or silo. It can be either measured by an instrument or evaluated by the human eye. To measure this, sugar crystals are dissolved and the colour of the resulting solution is determined by measuring its absorption using a spectrophotometer. Results from the two methods are very weakly correlated generally. For example, using this convenient instrument you can control the washing to avoid unnecessarily melting good sugar in your centrifugals. The colour profile of the sugar discharged by the centrifugals can tell you immediately when outputs from crystallizers, centrifugals or dryers are out of specification, pinpointing corrective actions needed, in real-time, and thus optimizing sugar quality, while minimizing water and steam consumption. Avoid waste from operating with large safety margins for the maximum colour limit. Avoid out-of-specification sugar reaching the silos. So you can readily adjust the washing and filling levels of the centrifugals to match the quality of the massecuite, and tailor the general level of wash water to avoid unnecessarily melting good sugar. Well-trimmed centrifugals produce lower colour sugar with the same washing, or the same colour sugar with less washing. Reducing of unnecessary washing will increase your throughput. By automatically detecting bad sugar, whether from a bad boil or a centrifugal malfunction you can adjust the process as soon as the sugar has been dried. Any sugar with colour outside specifications can be automatically diverted and remelted instead of ending up in the silo. Adjust your centrifugals to save washing time and produce more sugar with your centrifugal capacity, when the sugar has low colour. Improve your customer confidence and loyalty by continuously measuring all the sugar delivered in every shipment. Readily mix sugar of different qualities from different silos to meet different customers' specifications. The ColourQ can be conveniently installed on scrolls, belts and grasshopper conveyors. Once an instrument has been commissioned and calibrated the calibration remains stable for many years. The auto calibration unit ensure stability of the measurements Regular (hourly) auto-calibration are required to compensate for possible drift in the system, due (for instance) to slow accumulation of dust or splashes on the lens, or large variations in ambient temperature between cleanings. If a large deviation occurs between two auto-calibrations the instrument will stop taking measurements and give a warning that manual intervention is needed. The accuracy of the colour measurement allows the process to be run in the most efficient and economical way to reach the quality targets with no need for a large safety margin.
