ABSTRACT:
A method of generating electricity in synthesis gas in which a fuel is combusted in a gas turbine to generate the electricity that at least about 60 percent by volume is derived from a source independent of the synthesis gas. The synthesis gas is produced by reacting a hydrocarbon stream, by for example, partial oxidation, autothermal reforming or steam methane reforming. After the synthesis gas stream is cooled, heat is transferred from the heated synthesis gas stream to the fuel prior to combustion in the gas turbine. All or at least a portion of the heat is transferred at a temperature no greater than about 500° F. and at a flow ratio of the fuel to the gas turbine to the synthesis gas stream from at least about 1.5. The heating of the fuel to the gas turbine lowers fuel consumption and thereby the total expenses involved in generating electricity and syngas.
