The Anglo Platinum ACP Stage B project included a standby platinum-converting furnace with associated ancillaries. The standby converter is integral to Anglo Platinum’s sustained platinum production as the entire converting capability is routed through the single ACP plant. Hatch designed the converter to accommodate a quick changeover from duty to standby converter, to minimize production loss.

Prior to this Hatch provided EPCM services for Anglo Platinum’s Stage A converting process, which was designed to reduce sulphur dioxide emissions and expand converter capacity. Anglo Platinum adopted a process technology from Melbourne-based Ausmelt, and Hatch provided detailed design of the converter to ensure furnace integrity and full campaign life.

Based on lessons learned on Stage A, Hatch made layout and operational improvements in the design of Stage B. In Stage A, Hatch implemented a complex PCS 7 dual redundant process-control system. In Stage B, Hatch integrated new and existing software using an upgraded PCS 7 system in the operating environment. This challenge addressed risk assessments, which were worked into the planning and coding of the software implementation. Hatch integrated the software with the existing on-site operating system through its Woodmead, South Africa office.

Scope of Services
Hatch provided EPCM services for a second continuous matte converting plant at Anglo Platinum's Waterval smelter. Hatch was involved in the project from pre-feasibility to hot commissioning in early 2006.
