Batch & Continuous Digester Optimiser
At Anssum, we understand the challenges faced by pulp and paper mills in achieving consistent product quality and optimal reactor conditions. That’s why we’ve developed our advanced Batch & Continuous Digester Optimiser, utilising Model Predictive Control (MPC) technology.
Our solution leverages sophisticated algorithms and modeling techniques to predict product quality from historical and current reactor state. By constantly monitoring and manipulating reactor conditions, we’re able to ensure that product quality remains within a defined band, while maintaining optimal reactor conditions.
Our solution is flexible and can be implemented in a wide range of control systems. No additional hardware is required for our solution to work.
Case study
We recently worked with a pulp and paper mill to implement our Continuous Digester Optimiser solution. The mill was facing challenges with inconsistent product quality, resulting in increased costs and decreased customer satisfaction. Our team of experts worked closely with the mill to develop a customised solution that leveraged Model Predictive Control (MPC) technology to predict product quality and maintain optimal reactor conditions. The solution integrated with existing site models, developed from operational “trial and error”.
The mill achieved a 70% reduction in variability, leading to a 1.5% increase in wood yield and a significant reduction in production costs. Additionally, the improved consistency of product quality led to increased customer satisfaction and loyalty.
Kappa Variability
Reduced by 70%
Chemical Usage
Decreased by 2%
Wood Yield
Increased by 1.5%
Controller Utilisation
Increased by 25%
These results demonstrate the power and effectiveness of our Continuous Reactor Optimiser, and how Anssum can help your business achieve higher efficiency, reduce costs, and minimise your environmental footprint.
