System and method for liquefying natural gas with turbine inlet cooling

A system for processing natural gas to produce liquefied natural gas, the system comprising:

• one or more heat exchangers;
• a first refrigerant configured to cool the natural gas in the one or more heat exchangers;
• a first compressor driven by a first gas turbine, the first compressor configured to compress the first refrigerant, the first compressor having a first inlet air stream, wherein the first inlet air stream has a dry bulb temperature and a wet bulb temperature associated therewith;
• a second refrigerant configured to liquefy the cooled natural gas in a cryogenic heat exchanger;
• a second compressor driven by a second gas turbine and configured to compress the second refrigerant, the second compressor having a second inlet air stream, wherein the second inlet air stream has a dry bulb temperature and a wet bulb temperature associated therewith;
• a chiller located at an inlet of each of at least one of the first and second gas turbines, the cooler configured to chill, using the first refrigerant, at least one of the first and second inlet air streams from about the respective dry bulb temperature to a temperature below the respective wet bulb temperature;
• a separator located downstream of each chiller and configured to separate water in the chilled at least one of the first and second inlet air streams;
• and
• a wet air fin cooler that combines the separated water with an air stream to condense or sub-cool at least a portion of the first refrigerant passing through the wet air fin cooler, wherein the wet air fin cooler comprises
• a tube bundle through which the at least a portion of the first refrigerant passes;
• a spray header configured to deliver the separated water to the air stream, to thereby vaporize the water within the air stream;
• and
• a fan that forces the air stream and vaporized water over or across the tube bundle through which the at least a portion of the first refrigerant passes.
