ABSTRACT:
The invention is directed to a method of fueling gas turbines from natural gas reserves with relatively low methane concentrations. The invention permits the use of such reserves to be used to fuel gas turbines to generate electric power. The method of the invention includes providing a natural gas comprising not more than about 40 percent methane on a volume basis and mixing the methane of the natural gas with hydrogen gas to provide a hydrogen enhanced methane/hydrogen gas blend which has sufficient hydrogen to provide flame stability during burning. Thereafter, if required, the hydrogen enhanced methane/hydrogen gas blend is dehydrated to remove a sufficient amount of water to provide a flame stable hydrogen enhanced dehydrated methane/hydrogen gas blend. The hydrogen enhanced natural gas blend is used to fuel gas turbine generators.
