EPOC Paper Production

Due to the combination of complex production processes with on-site energy generation, the paper industry is particularly suitable for overarching optimisation, as is achieved with EPOC. In the paper mill, all plants are usually operated in accordance with the paper machine schedule. Plant shutdowns and restrictions are taken into account.

EPOC Paper Production supports the dispatcher in planning by significantly assisting in the creation of production schedules for the digester, scrubber, bleach and recovery line (evaporator, caustic pot, causticising).

The optimised production plans are recalculated every 15 minutes, always assume the current status of the plants and take all tank levels into account. This gives the dispatcher a good prediction of the development of the tank levels and the upcoming production rate changes at any time.

State-of-the-art algorithms are used for model selection and model identification. We place particular emphasis on robust modelling that delivers the desired results even in the presence of strong process noise. For the optimisation of the individual quality parameters (e.g. residual moisture), the methods of model predictive control (MPC) are integrated in EPOC. Based on the current process values, this control calculates optimal correction values of the machine settings and ensures the decoupling of the influences of individual parameters.

You benefit from a significantly smoother operation of your machines and more constant production rates. This also manifests itself in better product quality, as rapid production changes in particular trigger process fluctuations and thus negatively influence quality parameters.

EPOC Paper Production improves the long-term planning capability of your plant. This makes it easier for you to recognise bottlenecks in storage and supports you in planning plant shutdowns. You also get an overview of your mill’s electricity balance, which facilitates your negotiations with any electricity suppliers.
