Elipse Software’s solution is employed as the basic infrastructure for implementing an Advanced Control application with TriNMPC, Trisolutions’s non-linear, multivariable controller, at Klabin’s Monte Alegre Industrial Unit
Klabin is Brazil’s largest paper producer and exporter, and stands out as the leading manufacturer of paper and board for packaging, corrugated board packaging, and industrial bags, in addition to marketing timber in logs. It is also the only Brazilian company to simultaneously supply hardwood pulp (eucalyptus), softwood pulp (pine), and fluff pulp to the market. Established in Brazil in 1899, it has 18 industrial units (17 in Brazil and one in Argentina), sales offices in eight Brazilian states, and a branch office in the USA, as well as sales representatives and agents in many countries.
One of these units is the Monte Alegre Unit, in Telêmaco Barbosa, state of Paraná in South of Brazil. The company has implemented an Advanced Control system in this unit to optimize its operational efficiency and reduce variability of its key performance indicators. With this action, Klabin has assured that the maintenance of the process will be able to meet its due specifications.
The Advanced Control solution application has integrated several systems and fulfilled several steps in order to ensure the final solution operates according to the specifications. Among the systems employed in this solution, we highlight Elipse Plant Manager (EPM) and TriNMPC.
Developed by Elipse Software, the EPM is the application’s information management system. The platform is responsible for acquiring, storing, and supplying the process’s data, and is instrumental for setting up and providing the models to be used by the controller as well as for following up results and quantifying the benefits of the installation.
The TriNMPC, controller developed by Trisolutions, is able to operate both with linear models, such as the traditional MPC controllers, and with non-linear models. This ensures the highest spectrum of applications possible, thus generating better results.
The implementation of the Advanced Control solution has covered the following steps:
In this system, the TriNMPC controller is the responsible for accessing the process data via OPC server, and is managed from operational screens created directly at the SDCD. The EPM, on the other hand, is the responsible for providing data for tuning the PID control loops, identifying the process model to be used by the controller, monitoring the application’s performance, providing the assisted operations, and quantifying the gains from the Advanced Control application.
