METHOD AND APPARATUS TO IMPROVE OVERALL EFFICIENCY OF LNG LIQUEFACTION SYSTEMS

For a LNG (liquid natural gas) liquefaction system or plant that includes a gas turbine fueled by vaporized LNG and which receives compressed air, via an air compressor, as an input, a means and method to use relatively colder LNG vapor, in a heat exchanger disposed before the inlet to the turbine&#...

More Information
Summary:For a LNG (liquid natural gas) liquefaction system or plant that includes a gas turbine fueled by vaporized LNG and which receives compressed air, via an air compressor, as an input, a means and method to use relatively colder LNG vapor, in a heat exchanger disposed before the inlet to the turbine's air compressor, to remove heat from the air being inputted to the air compressor to improve overall efficiency of the systems or plants.
