项目摘要

In the smelting of copper, nickel or other metal ores, sulphur dioxide gas is generated, which, without treatment, can cause serious environmental damages and community health issues. An efficient sulphuric acid plant is vital for smelter operations as it converts harmful sulphur dioxide gas to sulphuric acid, which has extensive applications in the chemical industry. In recent years, Ontario has significantly tightened sulphur dioxide emission requirements and major metallurgical companies are taking all necessary measures to ensure smelter operations satisfy the tightened regulations. With increasingly stringent environmental regulations, a sulphuric acid plant has to be operated such that it reduces the sulphur dioxide gas to the required emission level. Modelling of acid plants in smelters is essential in providing a sound foundation for the needed enhanced process understanding, process control and optimizations. In this project, a sulphuric acid plant at an industrial smelter will be modelled using both fundamental principles and industrial data. Based on the developed model, the impact of smelter operational changes on the acid plant and sulphur dioxide emission will be investigated. This project will generate useful and timely results, as the involved industrial company is currently taking extensive measures to achieve significant reduction in sulphur dioxide emissions.

在冶炼铜、镍或其他金属矿石时，会产生二氧化硫气体，如果不加以处理，可能会造成严重的环境破坏和社区健康问题。高效的硫酸厂对于冶炼厂运营至关重要，因为它将有害的二氧化硫气体转化为硫酸，而硫酸在化学工业中有着广泛的应用。近年来，安大略省大幅收紧了二氧化硫排放要求，主要冶金公司正在采取一切必要措施，确保冶炼厂运营满足更严格的法规。随着环境法规日益严格，硫酸厂的运行必须将二氧化硫气体减少到所需的排放水平。冶炼厂中的酸厂建模对于为所需的增强过程理解、过程控制和优化提供坚实的基础至关重要。在该项目中，将使用基本原理和工业数据对工业冶炼厂的硫酸厂进行建模。根据开发的模型，将研究冶炼厂运营变化对制酸厂和二氧化硫排放的影响。该项目将产生有用且及时的成果，因为相关工业公司目前正在采取广泛措施，以实现二氧化硫排放量的大幅减少。
