According to Mining News Pro - Anglo American Platinum has signed a contract for Topsoe’s
world-leading Wet gas Sulphuric Acid (WSA) sulphur emissions control
technology for their platinum smelter facility in Polokwane, South
Africa. The statement said: “The WSA technology ensures compliance with
environmental regulations and offers a perfect match to the often
challenging requirements of metallurgical smelters and roasters. WSA is a
proven and very cost-efficient technology to control sulphur emissions
and produces commercial-grade sulphuric acid that can be sold.”
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 t per day of sulfuric acid. “Sulphur
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 sulphur (SO2)
and requires sulphur-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. Haldor Topsoe is a world
leader in high-performance catalysts and proprietary technologies for
the chemical and refining industries
