SO2 Emissions Reduction – A New Challenge for Aluminium Smelters

Sulfur dioxide (SO2) emissions represent an emerging environmental compliance challenge for the global aluminum smelting industry. As regulatory frameworks tighten worldwide and stakeholder expectations for environmental performance intensify, aluminum producers face increasing pressure to implement effective SO2 capture technologies. WorleyParsons Gas Cleaning developed this comprehensive analysis to address the unique emissions control requirements of aluminum smelters, drawing on proven technologies and operational experience from related industries including copper, nickel, and lead production facilities.

This technical publication provides aluminum industry stakeholders with a detailed benchmarking study comparing SO2 abatement technologies across multiple metallurgical sectors. The analysis examines capital investment requirements, ongoing operating costs, capture efficiency performance, and operational reliability across various technological approaches. By leveraging decades of experience in emissions control systems for non-ferrous metallurgy, WorleyParsons Gas Cleaning identifies proven solutions that can be adapted and optimized for the specific process conditions and emission characteristics of aluminum smelting operations.

The comparative cost analysis presented in this publication enables aluminum producers to make informed investment decisions regarding SO2 emissions reduction infrastructure. Understanding both capital expenditure requirements and lifecycle operating costs is essential for facility operators balancing environmental compliance obligations with economic competitiveness. The benchmarking against copper, nickel, and lead industries provides valuable insights into technology maturity, performance reliability, and potential operational challenges.

For aluminum smelting operations facing increasingly stringent SO2 emissions limits, this publication offers strategic guidance on technology selection and implementation planning. WorleyParsons Gas Cleaning's expertise in adapting proven emissions control technologies across diverse metallurgical applications positions the firm as a valuable partner for aluminum producers navigating the transition to enhanced environmental performance.
