L51424 Flue Gas Treatment Methods - Volume 2 SCR of NOx by Manually Controlled Ammonia Injection

A performance evaluation of a full-scale selective catalytic reduction process designed for post combustion abatement of nitrogen oxides (NOx) emitted from stationary internal combustion engines was performed. The system was installed on a 1,850 horsepower, gas fueled, Worthington UTC 168, internal combustion engine located at the Tennessee Gas Pipeline Company, East Bernard, Texas natural gas compressor station. The SCR system used vapor phase ammonia as a \selective\" reducing agent for the nitrogen oxides in the presence of a base metal catalyst. This study was undertaken as part of the PRCI program to evaluate the applicability of commercially available nitrogen oxides flue gas treatment systems for use on internal combustion engines used by the natural gas pipeline industry.
