Procesadora Industrial Río Seco S.A., Cia. De Minas Buenaventura, wholly owned chemical subsidiary, and Haldor Topsøe (Lyngby, Denmark; www.topsoe.com) have signed a contract for supply of a Wet gas Sulphuric Acid (WSA) plant for production of sulphuric acid at a new industrial operation in Peru.
The WSA plant is a multi-flexible unit that will both clean the H2S off-gases from an MnSO4 leaching process and burn elemental sulphur to make industrial grade sulphuric acid.
The WSA plant can operate on 100% H2S gas, 100% elemental sulphur and on any combination hereof.
Topsøe will supply all the basic and detailed engineering and equipment and materials required inside battery limits. This means that the project schedule can be greatly reduced as procurement can commence before the basic and detailed engineering of the plant is finished. The engineering is already on the way and the first design package has been supplied to Rio Seco.
Apart from engineering, equipment and materials, Topsøe’s scope of supply also includes license, catalysts and supervision services during construction, commissioning and start-up.
The start-up of the plant is scheduled to take place in 2012.
