29 May 2008 -- URS Corp. won a contract worth approximately $6.7 million to engineer and provide its SBS Injection technology for a Midwestern electric coal-fired utility. The technology for SO3 control is offered by URS and licensed through Codan Development LLC. The process will be installed on four 600 MW coal-fired boilers and is scheduled to begin operation in summer 2008. This will be the tenth application of this technology, and the first to inject sorbent directly upstream of the selective catalytic reduction (SCR) system to remove SO3 generated by both the boiler and the SCR catalyst. SBS Injection technology is designed to remove more than 95 percent of SO3 at low sorbent injection rates with the intention of eliminating the visible sulfuric acid plumes that are often produced by coal-fired power plants.
