Outotec has been awarded a contract to supply gas cleaning technology for Votorantim Metais to the Cajamarquilla zinc refinery. The value of the order is approximately EUR 16 million and it has been booked in Outotec’s fourth quarter 2014 order intake. Outotec’s scope of delivery includes engineering and supply of Peracidox sulfur dioxide (SO2) gas cleaning system and a scrubber for the production of sulfuric acid. In addition, Outotec provides installation, commissioning and startup services. The deliveries are scheduled to take place in 2015-2016.

Located east of Lima, the Cajamarquilla refinery produces refined zinc and the gas emissions from the zinc roasting circuits are processed in sulfuric acid plants. Outotec’s solution will reduce the refiner’s SO2 emissions and improve the quality of sulfuric acid produced by removing impurities.

“We have cooperated with Votorantim Metais since the late 1970s and this contract once again demonstrates that our customers have a strong confidence in our sustainable technologies. In this case, the SO2 emissions will be significantly reduced, which improves the air quality and allows the Cajamarquilla refinery comply with new environmental requirements with low operating costs,” said Kimmo Kontola, head of Outotec Americas region.
