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.

在铜，镍或其他金属矿石的冶炼中，会产生二氧化硫气体，而无需治疗，可能会导致严重的环境损害和社区健康问题。有效的硫酸植物对于冶炼厂的运营至关重要，因为它将有害的二氧化硫气体转化为硫酸，该硫酸在化学工业中具有广泛的应用。近年来，安大略省已大大收紧了二氧化硫的排放要求，而主要的冶金公司正在采取所有必要的措施，以确保冶炼厂运营能够满足收紧的法规。由于环境法规越来越严格，必须经营硫酸植物，以便将二氧化硫气体降低到所需的排放水平。在冶炼厂中对酸性植物的建模对于为所需增强的过程理解，过程控制和优化提供合理的基础至关重要。在这个项目中，将使用基本原理和工业数据对工业冶炼厂的硫酸植物进行建模。基于开发的模型，将研究冶炼厂对酸性植物和二氧化硫发射的影响。该项目将产生有用且及时的结果，因为所涉工业公司目前正在采取广泛的措施，以大大减少二氧化硫排放。
