Optimisation solution for German pulp mill

28 August 2023

Valmet will deliver a mill-wide optimisation solution to Mercer Rosenthal kraft pulp mill in Germany.

The production planning application and change management services will help to automate decision-making and optimise the production across the fibre line, recovery line and pulp dryer. An integral part of the solution is a two-year performance agreement for remote support via the Valmet Performance Center, ensuring long-term sustainable results.

The solution enables centralised, real-time decision-making. Operating decisions are based on the total mill production and inventory balance and forecast, and process area decisions are coordinated to maximise profit and stabilise the process.

“With mill-wide optimization, our goal is to produce pulp and energy more efficiently by further equalising and optimising plant operation,” said Christian Sörgel, Managing Director at Mercer Rosenthal.

A mill audit and a detailed re-optimise the past analysis was performed before the investment decision to minimise risks and evaluate the benefits. The analysis demonstrated how the production planning solution can be utilised to help balance the mill and achieve the desired pulp production.

Valmet will observe the entire mill production and inventory balance in real-time and consider both the current and future states of the mill. As a result, suboptimisation of individual processes that do not align with mill goals can be avoided. The optimisation also provides the ability to balance environmental sustainability with production, quality, and cost.
