Reducing Emission Rates with SCR Technology

Danvers, MA – Riley Power, Inc. based in Worcester, MA, a member of the Babcock Power Inc. family of companies, headquartered in Danvers, MA, received a contract to design and supply a Selective Catalytic Reduction (SCR) system for Salt River Project’s (SRP) Coronado Generating Station (CGS) near St. Johns, Arizona.

Riley Power will supply an SCR system for the Coronado Unit 2, which is rated at 435 megawatts. The SCR will reduce Nitrogen Oxide (NOx) emissions as part of SRP’s overall air quality improvement program at CGS. The SCR is expected to be commissioned by June 2014. SCR systems designed by Riley Power offer a unique Delta Wing® static mixing technology that provides uniform flue gas and ammonia mixing, high NOx removal efficiencies over a wide operating load range, and rapid start-up and commissioning. SCR systems furnished by Riley Power utilize technology under an exclusive license from Balcke Durr GmbH, and from other proprietary sources.

Jim Dougherty, President of Babcock Power Environmental, commented “We’re pleased SRP chose Riley Power’s SCR technology as part of its total emissions control program. When this project is complete, Coronado Unit 2 emissions rates should be among the lowest of any coal generation station in the country.”

SRP is the largest provider of electricity to the greater Phoenix metropolitan area, providing service to nearly 940,000 customers. SRP also is the metropolitan area’s largest supplier of water, delivering about 1 million acre-feet to agricultural, urban and municipal water users.

“This technology will be a valuable addition to our ongoing environmental efforts, through which we strive to improve energy efficiency,” Stated David G. Areghini, Associate General Manager of SRP.
