Erlangen/Germany (Siemens) – Siemens Metals Technologies received a contract from the Chinese steel producer Maanshan Iron & Steel Company Ltd. (Masteel) to install the first Meros plant outside Europe. The new facility will be built at the No. 1 Sinter Plant of the company's integrated iron and steel works located in Maanshan, Anhui Province, and will be capable of treating approximately 1,000,000m2 of sinter-offgas per hour. The Meros (maximized emission reduction of sintering) dry-cleaning process reduces emissions of dust, heavy metals, sulfur dioxide and organic compounds to levels previously unattained applying conventional technologies. The completion of this project is expected by mid 2009.
Masteel is one of the leading iron and steel companies in China and the largest industrial enterprise in Anhui province. The company produces approximately fifteen million tons of steel each year which is primarily sold as steel sections, wire rods and medium and thick plates. Furthermore, Masteel is the largest producer of train wheels in China. In order to drastically reduce environmental emissions from its No. 1 Sinter Plant, Masteel decided to have a Meros plant installed. A major reason for Maanshan's decision for Meros was because of the excellent results achieved with the new plant at the Sinter Plant No. 5 of the Austrian steel producer Voestalpine. Since the Meros plant start-up in August 2007, it has been operating at near 100% availability and pollutants are reduced in some cases to well over 90%.
