Prediction Simulation analySiS world pulppaper88 we can optimise our energy consumption to cater for the paper machines varying needs of pulp and steam Kenneth Lundstrm points out. The simulation tool is also useful when educating new people about how the production lines work. By letting them simulate different changes many production situations can be easily and realistically performed without disturbing the ongoing production. The PSA system was launched in May 2014 and after some modifications has proven to be a valuable tool. Every minute we get a prediction of the consequences of the paper machines pulp and steam consumption for the TMP plant and for the whole energy system. As not all of the refiners are the same size their production capacity and energy consumption varies. This means that we can optimise our energy consumption to cater for the paper machines varying needs of pulp and steam. Depending on production situations we are able to run the most cost efficient refiner combination. One major benefit with the PSA system is that the process operators at a glance get an overview of the present and the expected situation. Another advantage is the simulation possibility particularly when paper machines or TMP plants have runnability problems as it gives a good basis for decision making in advance on how to run the refiners when sudden changes in pulp and steam consumption occur The energy and pulp balances are shown in graphical form thus helping decision making to optimise the way to run pulp and steam production at all times. We are happy to see that this project with Hallsta has helped improve efficiency says Kenneth Lundstrm. We see great opportunities for the PSA system in many mills says Hans Hallin CEO Eurocon MOPSsys. Each mill has a different situation which means that the system has to adapt to the needs of the mill in question. It does not have be a situation with to drastic changes in production. The PSA system can also be a good support for decision making in mills where the consequences of a process change planned or unplanned need to be displayed in a clear way. Here the prediction and simulation possibilities can be very valuable. MOPSsys endeavours to apply the best technology available so that pulp and papermakers can achieve the greatest benefits from their mills and enterprise. Their mission is to help pulp and paper mills achieve substantial gains in product quality efficiency and throughput environmental stewardship and customer service through skilful application of real-time information throughout their organisations. Eurocon MOPSsys has more than a hundred installations in 18 countries and is a strategic part of the pulp and paper mills production and quality management. MOPS Prediction and Simulation Analysis PSA is a part of Eurocon MOPSsys product suite MOPS. MOPS is a Process Information Management and Quality Management System enabling the integration of all mill information systems. Hallsta 3. Kenneth Lundstrm was in charge of the development of the PSA system which provides predictions as well as possibilities to simulate consequences of different production situations.
