Gas Turbine Emission Reduction Systems

Meeting the strictest NOx and CO emissions standards while maintaining flexibility and reliability

The shifts to renewable energy sources such as wind and solar require the modern power grid to adapt, becoming more flexible and responsive to meet evolving market demands. Open cycle gas turbines (OCGT) are essential in providing the flexibility and expediency required, but their NOx emissions pose significant challenges. The NEM Selective Catalyst Reduction system using tempered air (T-SCR) offers a robust solution, allowing gas turbines to provide reliable and flexible power to the grid while complying with strict environmental emission regulations. By effectively reducing OCGT emissions to the most stringent NOx requirements achieving NOx levels as low as 2.0 ppm, our T-SCR system ensures clean, reliable energy, seamlessly stepping in when renewable sources fall short, and ultimately creating a healthier, more resilient power grid.

Yara Technology

Unmatched experience in catalyst technology with more than 100 units supplied globally

The NEM T-SCR uses Yara catalyst technology. NEM and Yara exclusively work together to offer T-SCR for any gas turbine type. Leveraging Yara’s advanced catalyst technology and NEM’s extensive expertise in heat recovery, this collaboration aims to deliver cutting-edge solution that increase grid reliability and ensures adherence to strict emission standards.

Hydrogen Ready

Equipped to meet the challenges of tomorrow, today

As the shift from natural gas to renewable fuel sources accelerates, controlling NOx emissions becomes more critical.
The NEM T-SCR system is fully hydrogen ready, reducing air pollution and helping meet stringent emission standards, ensuring the advantages of hydrogen as a fuel source are not compromised.

Leading Solution

To efficiently and reliably control emissions

The NEM T-SCR system contains a self-adjusting air injection unit ensuring the right mix of ammonia and air at every load. This also ensures maximizing NOx reduction and still achieve very low ammonia slip (< 2.0 ppm). This reduces catalyst aging by 15% and minimizes ammonia consumption, guaranteeing consistent emission control, enhanced performance, and lower operational expenses.

✓ Flexible operations
✓ Reduces the risk of catalyst degradation
✓ Lowers operational expenses
✓ Lowest total cost of ownership
