GE’s LM6000-PF mechanical drive aeroderivative gas turbine has been designed to operate as the driver for refrigeration compressors in floating and onshore liquefied natural gas plants. GE’s LM6000-PF mechanical drive is the highest efficiency gas turbine currently available for mechanical drive in the 40-60 MW range that delivers 15 parts per million NOx emissions. This enables lower fuel consumption per unit power output than competitive technologies, yielding fuel cost savings and lower NOx and CO2 emissions for turbine operators.
Compared to a heavy duty gas turbine in the 40-60 MW range with an efficiency of 34.2% at baseload conditions, GE's LM6000-PF mechanical drive aeroderivative gas turbine operating on natural gas with an efficiency of 42% avoids approximately 25,500 metric tons of CO2 per year for 43 MW of output, equivalent to the annual CO2 emissions of approximately 5,000 cars on US roads. Additionally, by premixing the air and fuel combustion mixture using a triple annular system, GE's LM6000-PF mechanical drive gas turbine maintains a very precise flame temperature that delivers 15 parts per million NOx emissions, helping operators meet current environmental regulations across the operating range.
