According to automation.com, it\u2019s going to be possible for paper and pulp mills to rely on automatic operation, like aircraft pilots do.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p>\u201cThe Autonomous Mill is \u201ca mill that runs itself with little or no human intervention\u201d utilizing<span class=\"Apple-converted-space\">\u00a0 <\/span>a Digital Twin coupling the Process Model with the Control Model. The development of the<span class=\"Apple-converted-space\">\u00a0 <\/span>Autonomous Mill is following the same path as that of the autonomous auto. First, smart sensors and instruments were required to reliably collect data. Next came secure and robust<span class=\"Apple-converted-space\">\u00a0 <\/span>communications methods to move the data from the mill floor to a control computer, and back. And finally comes the software and human expertise to combine equipment data with data pulled from process computers (DCS) and data mined from a mill\u2019s enterprise-wide computer (ERP) to \u201cnavigate\u201d the best path for production and profits.\u201d describes Brad S. Carlberg, the head engineer of control systems in BSC Engineering.<\/p>\n<p>Creating dynamic models of processes for individual areas of a world-class pulp mill can be difficult. The ability to import and export current configuration of the control system to and from a digital twin enables a complex control of process models, but also strategy verification of process management and application programming set for its implementation.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p>Once a dynamic process model or virtual process factory is built in the digital twins software, the planned behavior of a process factory is analyzed within various parameters \u2013 like pulp quality, production pace and operation settings and limitations. Virtual factory helps to reveal problems with the dynamic system\u2019s behavior, including problems with process management.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p>Another step is launching a digital twin, just like when a real factory is launched, through boot sequences, production pace changes, ore changes and stuff like that in order to find out what the factory will behave like. With a digital twin and a process model in connection with a control model, it is possible to analyze the behavior of an autonomous mill within an array of production speeds, operation settings and limitations.<\/p>\n<p>There have been a lot of textbooks and technical articles written about the processes in paper and pulp mills. To cover it in one article is not possible. However, the conclusions of the mentioned study show that by engaging digital twins, these factories can optimize a significant amount of their processes. Thanks to that, they are able to achieve significant energy savings, they save input chemicals and speed up the production pace.<\/p>\n<p>Let\u2019s talk about a recuperation model as an example. It can be optimized in the way to be operated with higher performance, better effectivity, increased reduction of green lye, minimized pollution, as well as reduced emissions. \u201cOptimization of these sequences can involve using \u201csmart sootblowing\u201d based upon furnace draft pressures and temperatures which would signal when to blow certain regions of the tubes. For example, if the temperature rises in a particular region, that would say that the tubes are becoming covered with soot and it would run the sootblowers in that region. You can also sequence the individual sootblower operation for optimal steam usage,\u201d describes Brad S. Carlberg.<\/p>\n<p>Similar results can be seen in the recausticisation processes, during the passage of material through fermentors, when washing, bleaching and within other steps as well.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p>Thanks to continuous and flawless automation in one or more parts of the factory, the operators will be able to intervene in the production much less and their roles are going to be changed to spectators. They are going to move from direct interventions in processes to whole factory supervision.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This year\u2019s conference of the paper and pulp industry focused on using advanced project management related to the digital twin technology.
