项目摘要
In mineral and metallurgical industry, smelters process sulfide ores to produce nickel, copper, cobalt, and precious metals. Smelting and refining of the metals are usually accompanied by sulfur dioxide and other gas emissions, which may cause undesirable working environment and polluted air. Smelter off-gas cleaning systems treat the off-gas emissions and minimize the environmental impact of the smelter processes. With growing awareness of the importance of environmental protection and tightened environmental policy, extensive study on smelter off-gas system is necessary. Optimal operation of the smelter systems requires tight monitoring and automatic control of the processes. Reliable models of the smelter systems are necessary to improve control and monitoring of the operation. This project proposes to model the smelter system in Falconbridge Ltd. using industrial operating data and fundamental principles. The smelter system includes many fundamental engineering unit operations. This project will investigate modelling techniques of these individual units, followed by plant-wide modelling with interactions of the engineering units. According to the dynamics of the variables, different model structures will be tested using conservation laws, semi-physical modelling or empirical identification. Model reduction will be conducted to generate the models that can be easily incorporated into process control development. An adaptive identification method with learning schemes will be investigated and developed specifically for modelling the time-varying characteristics of the smelter off-gas system. With the derived models, the control schemes for the smelter off-gas system will be investigated. Results of this project are expected to build necessary foundation to further improve the smelter operation and result in better environment and significant economic benefits.
在矿产和冶金工业中,冶炼厂处理硫化矿石以生产镍、铜、钴和贵金属。金属的冶炼和精炼通常伴随着二氧化硫等气体的排放,这可能会造成不良的工作环境和污染的空气。冶炼厂尾气净化系统处理尾气排放,最大限度地减少冶炼过程对环境的影响。随着环保意识的增强和环保政策的收紧,对冶炼厂烟气系统进行广泛的研究是必要的。冶炼系统的最佳运行需要对过程进行严密的监控和自动控制。为了改进对操作的控制和监测,必须建立可靠的冶炼系统模型。该项目建议使用工业运行数据和基本原理对鹰桥有限公司的天然气冶炼系统进行建模。冶炼系统包括许多基本的工程单元操作。这个项目将研究这些单个单元的建模技术,然后是整个工厂的建模与工程单元的相互作用。根据变量的动力学,将使用守恒定律、半物理模型或经验识别来检验不同的模型结构。将进行模型简化,以生成可轻松纳入过程控制开发的模型。将研究和开发一种带有学习方案的自适应辨识方法,专门用于对冶炼厂烟气系统的时变特性进行建模。利用所建立的模型,对冶炼厂烟气系统的控制方案进行了研究。预计该项目的成果将为进一步改善冶炼厂的运行状况奠定必要的基础,并产生更好的环境和显著的经济效益。
