摘要： A gas turbine cycle that utilizes the vaporization of liquefied natural gas as an intercooler in an open loop gas turbine system. The system provides an increase in gas turbine cycle efficiencies while providing a convenient system for vaporizing liquefied natural gas. The systems and methods of the present invention permit the vaporization of liquefied natural gas using air that has been compressed in a first compressor, with the resulting cooled air being easier to compress and/or having fewer contaminants therein for compression in a second compressor. As the air is easier to compress, less energy is needed to operate the second compressor, thereby increasing the efficiency of the system. Additionally, unlike prior art systems that use water as an intercooler, no additional equipment is needed to cool the vaporized natural gas, such as cooling towers.
