Selective Catalytic Reduction (SCR) is a post-combustion method to reduce the oxides of nitrogen (NO/sub x/), present in flue gases such as gas turbine exhaust streams, to N/sub 2/ and water. It involves the injection of ammonia and the use of a catalyst module to promote the reaction to obtain high efficiency (60-86+%) NO/sub x/ reduction. Several operating parameters can influence catalyst performance to include temperature, gas flow distribution, presence of sulfur compounds and catalyst age. This paper examines the impact of a SCR integration in a gas turbine heat recovery steam generator (HRSG) design/operation. Limitations on HRSG load and following capabilities, effect on capital cost and overall performance and current SCR system experience represent a number of areas that are examined.
