ALSTOM has signed an agreement with Vosteen Consulting of Germany to market and sell its innovative technology of bromine additives, for the removal of mercury from coal-fired boilers and other industrial processes. According to the terms of the agreement, ALSTOM has exclusive rights to market this technology to the power generation industry in the United States and Canada.
Available in KNXTM coal additives and systems sold exclusively by ALSTOM, this technology significantly enhances mercury oxidation in coal-fired boilers and has already been demonstrated at numerous utility plants throughout North America. Oxidized mercury is known to be easier to collect in downstream air pollution control equipment, including ESPs, FFs, DFGD and WFGD systems.
Recent tests have demonstrated the potential of the KNX coal additive to not only enhance mercury oxidation but, in some cases, even improve the inherent mercury removal of an existing boiler and downstream air pollution control system, without the use of activated carbon injection. On boilers that incorporate WFGD systems for SO2 removal, KNX technology may enhance total mercury capture, regardless of the coal being combusted. The KNX injection system is extremely simple and cost-effective to retrofit to any coal-fired boiler.
ALSTOM has extensive experience in mercury emission control and has designed and supplied a number of dedicated, mercury control systems that include activated carbon injection systems. Over the past 15 years, ALSTOM has retrofitted some 20 commercial units with activated carbon injection into a dedicated, polishing fabric filter. These systems, combined, have achieved over 1.5 million hours of demonstrated reliable operation.
Vosteen Consulting is based in Cologne, Germany and specializes in research and development of mercury removal from power generation and industrial processes. KNX is a trademark of ALSTOM Power Inc.
