October 9, 2011 - Metso will supply an advanced batch cooking optimization solution to the specialty cellulose pulp mill of AV Cell in Atholville, Canada. The startup is scheduled for the end of the fourth quarter in 2011. The delivery includes Metso Batch Cooking Optimizer SI with a Modified Cooking Factor control along with Metso's AT analyzer for the automatic measurement of SO2. Metso Batch Cooking Optimizer is designed to manage the pulp quality and production rates, including digester scheduling. It plays an important role in the control of raw materials and energy flows, as well as such variables as production rate, wood species, Kappa level, and disturbance management. The model-based quality control automatically adapts itself to changing process conditions and automatically affects the long-term Kappa number deviation. Over the past decades, Metso has delivered dozens of batch cooking optimizers to pulp mills around the world, also for the production of dissolving pulp. AV Cell will use the solution especially to control the quality of its dissolving grade chemical pulp in its batch digesters. The mill’s entire capacity of 119,000 tons is exclusively used by the AV Group's viscose staple fiber units in India, Thailand, Indonesia and China. Metso is a global supplier of sustainable technology and services for mining, construction, power generation, automation, recycling and the pulp and paper industries. We have about 29,000 employees in more than 50 countries.
