The systems and methods described herein integrate a supercritical fluid power generation system with a LNG production/NGL separation system. A heat exchanger thermally couples the supercritical fluid power generation system with the LNG production/NGL separation system. A relatively cool heat transfer medium, such as carbon dioxide, passes through the heat exchanger and cools a first portion of extracted natural gas. The relatively warm heat transfer medium returns to the supercritical fluid power generation system where a compressor and a thermal input device, such as a combustor, are used to increase the pressure and temperature of the heat transfer medium above its critical point to provide a supercritical heat transfer medium. A second portion of the extracted natural gas may be used as fuel for the thermal input device.

Natural gas processing using supercritical fluid power cycles

A method of removing liquid from the surface of an airfoil of equipment that handles a wet gas mixture. The airfoil has at least one interior passage, such as a bore, for travel of air or other gas through the interior of the airfoil. A series of holes are cross drilled from one or both exterior surfaces of the airfoil to the passage. Forced air or other gas is introduced into the passage such that the air or other gas is expelled to the surface of the airfoil via the holes, thereby removing the surface liquid.
