Finnish mining equipment developer Metso Outotec has launched a modular Converter Hood System for horizontal converter vessels used in the smelting process.

The new system, which is suitable for greenfield and brownfield installations, has an SO2 (sulfur dioxide) gas capture capability of 99%, minimising the environmental impact. The modular design enables quick on-site assembly, so the system is ready to use with minimum plant downtime.

"We are excited to launch the new Converter Hood System. Besides its excellent gas capture capability, the system design ensures a well-controlled ingress air flow that improves process gas quality. The primary converter hood's advanced water-cooling system increases process reliability and improves safety in the converter aisle, while also reducing maintenance needs and prolonging equipment lifetime," explains Jonny Eliasson, Director, Precious Metals at Metso Outotec.

Metso Outotec has extensive experience in the field of Converter Off-Gas plant design and construction, developed over several decades and enhanced by the company's continued activities in the research and development of the process.

The company added that the benefits of the Metso Outotec Converter Hood System included excellent SO2 gas capture for outstanding environmental performance as well as improved safety in the converter aisle.

In addition, it enables well-controlled ingress air flow for improved process gas quality, and prolonged equipment lifetime thanks to the design and advanced water-cooling system.
