GE says its mobile aero-derivative gas turbines can now meet the most stringent emissions standard requirements. The first system was successfully installed on four GE TM2500 aero-derivative gas turbines in California, and the developed solution is now available for GE TM2500 units globally, the company says. The solution includes GE’s proven Selective Catalytic Reduction (SCR) technology, and effective post-combustion control systems to help lower emissions from thermal power generation.

The company says that TM2500 aero-derivative gas turbines are installed in Nigeria, Angola, and Ghana, to provide much-needed power. These turbines produce lower emissions than diesel generators when operating on gas, and the availability of an SCR solution enables customers further to reduce NOx and CO emissions by 90%.

The SCR technology removes typical emissions through a catalytic converter, transforming the nitrogen oxides in the exhaust gas into water vapor and nitrogen.

Aero-derivative gas turbines are often used for emergency power and peaking power worldwide, and can also complement renewable energy resources perfectly.
