Growing concern over climate change, combined with ever stricter environmental regulations and compliance deadlines, have increased international demand for air quality control systems in power plants.
Saudi Arabia
Alstom has signed a contract worth approximately €40 million as subcontractor of Chinese EPC contractor SEPCO III Electric Power Construction Corp. for the design, supply and installation of two 660 MW seawater FGD systems** at units 1 & 2 of a new oil-fired Rabigh power plant currently being built in Saudi Arabia. Alstom’s technology uses no chemicals, only seawater and air, to remove 97% of sulphur dioxide from the plant, allowing the plant to conform to the country’s environmental requirements. The power plant is owned by a consortium of Saudi Arabian companies Acwa (40% ownership) Kepco (40%) and SEC (Saudi Electricity Corporation; 20%) and is due to be commissioned from 2012 onwards.
India
Alstom’s leadership in air quality control extends to industries outside the power sector, as demonstrated by a contract of approximately €70 million signed with Hindalco Industries Ltd in India. Under the terms of this contract, Alstom will design, engineer, supply, install and commission gas treatment plants at the Mahan and Aditya aluminium smelters in the states of Madhya Pradesh and Orissa. The plants, due onstream in early 2012, will capture, filter and recycle corrosive gas produced by the smelters, notably hydrogen fluoride, improving the quality of the air and thus conforming to Indian environmental requirements.
“The selection of Alstom for these two contracts confirms Alstom’s leadership in environmental control systems for both power plants and industrial plants. Besides this technological leadership, the award of these contracts is proof of Alstom’s rock solid reputation in project execution as well as Alstom’s truly global footprint, combining our first class technologies, developed in our R&D and technology centres, with our strong local project execution capabilities in our execution offices around the globe,” says Andreas Lusch, Senior Vice President and Head of Thermal Systems.
Alstom has the world’s largest installed base in air pollution control, with over 100,000 MW worth of wet and dry FGD systems and over 40 years of experience in FGD design.

*Flue gas desulphurization (FGD) systems remove sulfur dioxide and particulate matter released from coal-fired steam generators. Alstom offers both wet and dry processes for FGD to meet the varying economic requirements of its customers.
** Suitable for thermal power stations, metal smelters and oil refineries, Seawater Flue Gas Desuphurisation (SWFGD) efficiently treats flue gases containing 20-6500 ppm of sulphur dioxide. The compact design provides a good solution to both new and retrofit installations and is especially cost-efficient on applications already using seawater as a coolant. The first Alstom SWFGD plant started operation in 1968. Today, more than 90 of these units have been installed or are under construction in different parts of the world, corresponding to a total equivalent capacity of about 32 GW of flue gas desulphurisation.
