System dynamics and discrete event simulation of copper smelters

摘要: Discrete event simulation (DES) is an appropriate framework for the plant-wide analysis of copper smelters. These smelters apply a common set chemical reactions: copper-iron sulfides are blasted with oxygen-enriched air, sending iron into slag phase and sulfur offgas. Moreover, conventional exhibit similar operational dynamics: smelting furnace operates continually, feeding alternating converters that produce batches blister copper. The thermochemical commonalities integrated within DES framework. This serves as basis to begin evaluating system dynamics individual For complex problems, should be developed in phases, incorporating feedback from different personnel who have complementary perspectives. Sample computations provided this paper based on Hernan Videla Lira smelter, whose production constrained by meteorological conditions.
