June 30, 2011 - Haldor Topsøe signed a contract to build of a wet-gas sulfuric acid (WSA) plant for the production of sulfuric acid at Rio Seco’s new industrial operation in Peru.   Haldor Topsøe signed a contract to build of a wet-gas sulfuric acid (WSA) plant for the production of sulfuric acid at Rio Seco’s 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 sulfur to make industrial grade sulphuric acid, the company said.  The WSA plant can operate on 100% H2S gas, 100% elemental sulfur and on any combination hereof, officials said.  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.   Rio Seco’s managerial team said: “We are very pleased with our agreement with Topsøe for the supply of a WSA plant as this is an important unit in our new production complex.  “Specifically, we are pleased that Topsøe has qualified people working locally in South America who were able, in combination with the head office in Copenhagen, Denmark, to negotiate an LOI and sign a contract with us within only a few months.
