OPT800 Caust delivers superior control and monitoring of the causticizing process, helping mill personnel improve process efficiency and product quality, while also reducing environmental impact. The Advanced Process Control solution stabilizes white liquor quality controlling and managing the green liquor TTA, causticizing efficiency and production rate changes.
In operation of the causticizing process, the main objective is to maintain stable white liquor production rate and quality. The specific challenge is to achieve optimal chemical conversion in the causticizing reaction, enabling a high causticizing efficiency while ensuring easy separation of the lime mud. Disturbances such as changes in green liquor quality, lime availability and production rate add to the complexity of problem. Poor performance of the causticizing process can have significant impacts on the white liquor quality, which can cause larger quality and production rate disturbances throughout the cooking process.
OPT800 Caust solves these challenges by providing tighter control of the causticizing process, reducing variability for better white liquor quality while also increasing capacity by up to 7%.
