Metso introduces advanced process control solution for chemical pulp mills

HELSINKI, Oct. 1, 2009 (Press Release) - Metso have pooled experience and resources to develop a new elite Metso Advanced Process Control (mAPC) solution to meet the ever-increasing demand for cost efficient and environmentally friendly pulp production. In collaboration with pulp mill engineering and operations personnel, Metso's unique blend of process, machinery and automation expertise have been combined to provide this new generation process control solution. mAPC with the ability to intelligently manage multivariable processes, brings improved performance to all pulp mill processes. Using predictive controls, shift to shift variations are eliminated in all departments from the wood yard to pulp dryer. mAPC enables production and quality targets to be met quicker while optimizing energy, chemical and raw material usage for additional savings and environmentally clean operation.

The new mAPC for chemical pulping has been developed from experience with optimization controls installed in more than 200 pulp mill processes around the world. These solutions, based mainly on predictive process models, have achieved a high level of performance in both fiber and recovery line processes. Controls are enhanced in many cases by Metso's Kajaani process analyzers, which measure process conditions, chemical reaction rates and product quality. Further optimization, made possible by mAPC, has produced good returns on investment by significantly increasing process productivity and efficiency, stabilizing product quality and increasing energy generation while reducing energy and chemical consumption.
