PULP MILL OPTIMISATION WORLD PULPPAPER 41 When Mondi the global paper and cardboard producer decided to modernise their largest pulp mill in Poland they chose ABB as partners to help improve and optimise the mills two pulp production lines. For this undertaking ABB developed an advanced process control solution based on model predictive control and soft sensors. The modernisation resulted in an improvement of 56 By Abhijit Badwe and Ramesh Satini ABB Pulp and Paper Control Systems Singapore Pulp mill optimisation no longer pulp fiction One of the first things that the newly formed Mondi Swiecie did was look for ways to improve the pulp mills production process Advanced process control at the largest pulp mill in Poland has increased productivity and stabilised the processes in the cooking and pulp washing lines in a way that conventional methods of DCS control could not percent in pulp quality as well as standardised solutions that can now be offered to other pulp mills. In 2011 Mondi embarked on a project to look for ways to improve pulp quality and chemical usage enhance production and reduce cost for its two pulp production lines in the Mondi Swiecie pulp mill. A number of factors played a role in this search. One was the companys policy of reducing the environmental impact of its operations and in pulp mills this means cutting the use of heat energy and chemicals. A second factor was the requirement to improve the quality of the product. Mondi Swiecie mostly makes containerboard corrugated packaging and industrial bags which are surprisingly high-tech products. Thirdly there were the universal goals Producing consistently high-quality pulp with advanced process control
