Abstract:
A method of fueling a gas turbine with methane gas from natural gas reserves having from about 40 to about 80 volume percent methane, the method comprising:providing a first natural gas stream from the natural gas reserve; separating inert gases from methane gas in the first natural gas stream to provide a separated methane gas and a separated inert gas; blending the separated inert gas with a second natural gas stream having from about 40 to about 80 volume percent methane; and using the blended stream of separated inert gas with said second natural gas stream to fuel said gas turbine wherein after blending the amount of inert gas in the blended stream is sufficient to increase the output of a gas turbine by at least about 5 percent as compared to a turbine fueled with pipeline quality natural gas.
