The China Nonferrous Metals Society recently held an evaluation meeting on scientific and technological advancements in Beijing, where experts unanimously recognised two breakthrough achievements by the Shenyang Aluminum and Magnesium Institute. These include the "Full Cycle Optimisation Technology for Aluminum Reduction Cell Design, Construction, and Operation Based on Model and Data Integration" and the "Development of Organic Flue Gas Treatment Technology and Equipment for Carbon Products in the Aluminum Industry." Both were deemed to have reached a world-leading level.
Full cycle optimisation technology of aluminium reduction cell design-construction-operation based on model and data fusion
To address the issues of isolated data storage and fragmented information exchange during the design, construction, and operation stages of aluminium reduction cells, a new life cycle optimisation system was developed, integrating data and mechanism fusion. This included the creation of dynamic simulation technology based on distributed detection and model reduction, along with introducing a dynamic production management and control strategy for aluminium reduction cells. An independent life cycle optimisation platform and an industrial app were also developed, enabling seamless data integration across the design, construction, and operation phases.
Development of organic flue gas treatment technology and equipment for carbon products in the aluminium industry
To address the challenges of complex organic compounds and the difficulty in purifying flue gas generated by aluminium anode production, a new technology, "flue gas cooling and carbon powder adsorption of organic pollutants in series," was developed for flue gas pretreatment. An adsorption reactor was also designed specifically for capturing organic components in calcination flue gas, resolving the issue of frequent dust collector bag blockages in calcination purification systems.
A comprehensive treatment technology for asphalt flue gas in the moulding and asphalt melting sections was created, utilising residual heat from high-temperature flue gas at the RTO outlet. This innovation also tackled the problems of regenerator coking and secondary organic waste gas analysis. By effectively mitigating the environmental risks associated with carbon production in the aluminium industry, this technology offers a solution for upgrading traditional carbon flue gas purification systems.
