Anglo American Platinum chooses WSA for cost-efficient environmental compliance

Copenhagen, 27 August 2018 – The WSA plant is designed to drastically reduce emissions of SO2 from the platinum smelter from around 90,000 mg/Nm3 to less than 1,200 mg/Nm3. It will produce up to 148 tons per day of sulfuric acid.

“Sulfur emissions control has become a business prerequisite in the South African smelter industry. We wanted a solution that would ensure environmental compliance now and in the foreseeable future as well
as make a convincing business case. WSA ticked both fields,” says Dr. Lloyd Nelson, Head of Smelting & Refining Technology, Metallurgy, Anglo American Platinum.

Newly enforced regulations in South Africa limits the emission of sulfur (SO2) and requires sulfur-emitting facilities to install an abatement technology.

WSA is a leading sulfur emissions control technology for wet gas applications. Its recovery of process heat makes it extremely energy-efficient and consequently it uses no or very little support fuel. WSA does not
produce any waste and requires only minimal cooling water.

The WSA plant ordered by AAP will be the second in Africa. As governments and investors across the continent implement stricter environmental guidelines, the technology is expected to be adopted by many more African companies. Around the world, 160 WSA plants have been commissioned. The contract covers basic engineering, license, proprietary equipment, catalyst, training, and supervision services. Hatch in South Africa have been selected by AAP for Engineering, Procurement, and Construction Management (EPCM) and will be managing the completion of the project on behalf of AAP.
