Siam Cement in Thailand has placed an order with FLSmith for an air pollution control system for three cement lines at its Thungsong plant. By the installation Siam Cement will comply with new environmental legislation in respect of SO2 removal.
The order consists of engineering, key parts, fans and supervision, and will be commissioned at the end of 2011.
Environmental legislation is continually strengthened, most recent with the NESHAP (National Emissions Standards for Hazardous Air Pollutants) rules, to become effective in the US from 2013. As a result the vast majority of all cement plants in the US will need to upgrade their air pollution control systems over the next years.
At Norcem Brevik, Norway, FLSmidth has used the patented GSA (Gas Suspension Absorbers) technology. The GSA combines a compact design with low operating costs and low emissions. The GSA is capable of simultaneously removing SO2, HCl, heavy metals (including mercury) and dioxins – all components for which the NESHAP rules apply.
Recent measurements at Norcem Brevik have exceeded expectations to the performance of the GSA. The results were awaited by Siam Cement before they finally decided for the GSA, but with the results in hand Siam Cement was convinced about the GSA being their preferred solution, and the contract was concluded.
The GSA has proven compliance with even the most stringent emission requirements. With these two orders FLSmidth has established the best reference platform for the GSA. No other supplier has similar references within this technology. It is thus an important step in ensuring FLSmidth’s position within air pollution control and strengthens FLSmidth as a leading Cleantech supplier for the Cement and Minerals industries.
