Innovation in Catalyst Technology: Using Direct Injection of Liquid Ammonia Provides Many Benefits

Jeff Wirt, Director of Catalyst Systems at EnergyLink International sat with Turbomachinery to discuss a new direct injection system for liquid ammonia that streamlines Selective Catalytic Reduction (SCR) in gas turbines. By eliminating the need for vaporization skids, blowers, and extensive piping, the technology reduces costs, improves NOx reduction efficiency, and lowers parasitic power consumption. Full-scale field tests confirm the system not only meets regulatory limits but also outperforms traditional SCR methods while offering faster deployment for a range of turbine models.
