Outotec, specialist in minerals and metals processing technology, has recently agreed with Boliden, the Sweden-based mining and smelting company on the main design and delivery of proprietary equipment for a sulfuric acid plant to be built in connection with the Harjavalta nickel and copper smelter in Finland.
The new gas cleaning and sulfuric acid plant solutions designed by Outotec will process off-gas from the smelters into high grade industrial sulfuric acid. The plant will meet all of the current and planned European environmental requirements through innovative gas cleaning, production of sulfuric acid and highly efficient heat recovery system. The first construction phase of the sulfuric acid plant is expected to be operational in May-June 2018.
“We are extremely pleased that our long-term partner Boliden awarded us this order. Outotec’s advanced gas cleaning and sulfuric acid plant solution will improve the environmental performance of the Harjavalta smelter and reduce the need for external energy, which will shorten the payback time of the investment,” says Robin Lindahl, Head of Outotec’s Metals, Energy & Water business unit.
