Simulação dinâmica de processos em projetos de usinas de beneficiamento de minérios

Abstract

In the last decade we saw the number of new projects of ore treatment plants increase significantly due to high demand of the consumer market. As this occurs, we saw the time of maturation and development of projects decreases considerably, there is no more time to deliver a quality and consistent project across the design disciplines of a project. Nowadays these types of projects are at the order of billions of dollars and there are several risks to implement them. Therefore, inside this context, the use of dynamic process simulators has become critical. The idea of using a dynamic simulator process is innovative and drastically reduces the possibility of engineering errors, project delays implementation and the starting time of new plants. With a simulator ispossible to validate the project design in several stages (conceptual, basic and detailed design), check the logic and control loops, accomplish the training of operators in a virtual plant, among other endless possibilities. Will be presented the applications and benefits that a dynamic process simulator has, taking into account the organizationalstructure of a capital project that follows the FEL methodology, which is widely used in the currently management of huge projects. To exemplify and illustrate the raised points, will be used a dynamic simulation software, called IDEAS, which belongs to ANDRITZ Automation Solutions. With the help of the software, will be created a dynamic model of a typical operation of comminution, grinding
