SCR Systems for Gas Turbines

Selective catalytic reduction (SCR) systems have been utilized in various fossil fuel-fired combustion applications for decades as a means to control harmful emission levels. As gas combusts in turbines in combined cycle or simple cycle plants, nitrogen oxide (NOx) is formed—this can create intense environmental health hazards, including smog and acid rain. HANLAN excels at the design and installation of customized SCR equipment that will dramatically reduce the harmful emissions of your gas turbines.

How does SCR NOx Reduction Work?

Within the SCR equipment, an ammonia-based reagent is injected into the post-combustion flue gas which causes a specific type of reaction, known as a reduction, with the nitrogen oxide. In the presence of a catalyst like vanadium or tungsten oxide, this reduction is possible at much lower temperatures than selective non-catalytic reduction (SNCR). This improves the NOx reducing capabilities as a result. The byproduct of this chemical reduction is harmless nitrogen and water vapor.

The primary components of a typical selective catalytic reduction system include the aqueous ammonia storage and forwarding system, vaporization and dilution air equipment, the ammonia injection grid (AIG) and the SCR and CO catalysts installed in a custom-designed reactor housing. SCR gas turbines can usually be retrofitted into existing power plant systems or used in the initial construction to optimize the efficiency, reliability, and performance of your system, and they will meet rigorous energy standards. The team of engineers at HANLAN has extensive experience building site-specific SCR systems for power plants and petrochemical processing sites across the country. By utilizing the deep wealth of knowledge and resources of our team, we can deliver the best performing SCR equipment in the industry.
