Solvay launches new product for air-pollution control

Gerald Ondrey

Solvay S.A. (Brussels, Belgium; announces today that its subsidiary Solvay Chemicals, Inc. is expanding its portfolio with a new product named SOLVAir Select 300, which is designed for air-pollution control applications, in particular, the treatment of sulfur dioxide (SO2) in fluegas. The Group is planning total investments in excess of $40 million at its Green River, Wyoming, plant to manufacture this new sodium-bicarbonate-based product using a proprietary, innovative technology.

Initial production capacity for SOLVAir Select 300 will be 125,000 ton/yr, and the plant is designed to be easily expanded to accommodate the anticipated growth of market demand that will result from tightening air pollution regulations. The startup of production — using a process that will improve the environmental efficiency of the Green River plant — is scheduled in 2010.

SOLVAir Select 300 is dry-injected in the ducts of power plants or industrial manufacturing units whose fluegases require treatment. The sulfur oxides (SOx) in the flue gases react with the sodium bicarbonate present in SOLVAir Select 300 to form sodium sulfate, a solid, fine particulate matter that can be captured by control equipments such as bag filters or electrostatic precipitators.
