Abstract: An apparatus and method for increasing efficiency of a gas turbine and a marine structure having the gas turbine are disclosed. The marine structure has a cargo tank for storing cryogenic liquefied natural gas (LNG) and a gas turbine for generating electric power. The marine structure further includes a heat exchanger to cool air for combustion supplied to the gas turbine using a cold source or cold heat of the LNG stored in the cargo tank, a heat transfer medium circuit to indirectly transfer the cold source of the LNG stored in the cargo tank to the heat exchanger, and a heater to heat a heat transfer medium having undergone heat exchange with the air for combustion while passing through the heat exchanger. The temperature of air supplied to the gas turbine is lowered using the cold source generated upon regasification of LNG in the marine structure, thereby increasing the efficiency of the gas turbine.

Abstract: An apparatus and method for increasing efficiency of a gas turbine and a marine structure having the gas turbine are disclosed. The marine structure includes an ambient LNG vaporizer for regasifying cryogenic LNG via heat exchange with air and the gas turbine for generating electric power. The marine structure includes a moist-air mixing chamber disposed at an upstream side of the gas turbine, a condensed-water nozzle to spray condensed water, generated from air during the heat exchange in the LNG vaporizer, into the moist-air mixing chamber; and a cold air supply pipe to supply air, cooled by the heat exchange in the LNG vaporizer, to the gas turbine via the moist-air mixing chamber. The method reduces the temperature of air supplied to the gas turbine by condensed water or cold air generated during regasification of LNG through the ambient vaporizer in the marine structure, thereby increasing the efficiency of the gas turbine.

Abstract: Disclosed is a liquefied natural gas storage apparatus. The apparatus includes a heat insulated tank and liquefied natural gas contained in the tank. The tank has heat insulation sufficient to maintain liquefied natural gas therein such that most of the liquefied natural gas stays in liquid. The contained liquefied natural gas has a vapor pressure from about 0.3 bar to about 2 bar. The apparatus further includes a safety valve configured to release a part of liquefied natural gas contained in the tank when a vapor pressure of liquefied natural gas within the tank becomes higher than a cut off pressure. The cut off pressure is from about 0.3 bar to about 2 bar.

Abstract: Disclosed is a liquefied natural gas composition. The composition contains methane, ethane and propane and butane. The composition contains a substantial amount of butane while being substantially free of hydrocarbon molecules larger than butane.

Abstract: A fuel gas supply system of a vessel, such as an LNG carrier, is provided for supplying fuel gas to a high-pressure gas injection engine of an LNG carrier, wherein LNG is extracted from an LNG storage tank of the LNG carrier, compressed at a high pressure, gasified, and then supplied to the high-pressure gas injection engine. In one embodiment, the system includes a boil-off gas reliquefaction apparatus for reliquefying boil-off gas generated in the LNG tank.

Abstract: Disclosed are a method and an apparatus for treating boil-off gas generated in an LNG storage tank of an LNG carrier for transporting LNG in a cryogenic liquid state, the LNG carrier having a boil-off gas reliquefaction plant, wherein an amount of boil-off gas corresponding to a treatment capacity of the reliquefaction plant among the total amount of boil-off gas generated during the voyage of the LNG carrier is discharged from the LNG storage tank and reliquefied by the reliquefaction plant. The boil-off gas treating method and apparatus can maintain an amount of boil-off gas discharged from an LNG storage tank at a constant level by storing in the LNG storage tank, instead of discharging and burning, surplus boil-off gas which has not been returned to the LNG storage tank through the reliquefaction plant among the total amount of boil-off gas generated in the LNG storage tank, and can prevent waste of boil-off gas and save energy by allowing an internal pressure of the LNG storage tank to be increased.

Abstract: Production of a dielectric coating on a substrate whereby a poly(arylene ethers) or fluorinated poly(arylene ethers) layer is cured by exposure to electron beam radiation. A wide area electron beam is used which causes chemical reactions to occur in the polymer structure which are thought to cause crosslinks between polymer chains. The crosslinks lead to higher mechanical strength and higher glass transition temperature, lower thermal expansion coefficient, greater thermal-chemical stability and greater resistance to aggressive organic solvents. The polymer layer may also be optionally heated, thermally annealed, and/or exposed to UV actinic light.

Abstract: A process for the preparation of substrates used in the manufacture of integrated circuits wherein spin-on low dielectric constant (low-k) polymer films are applied on semiconductor substrates. A non-etchback processing of spin-on low-k polymer films, without losing the low dielectric constant feature of the film, especially in between metal lines, is achieved utilizing electron beam radiation. A polymeric dielectric film is applied and dried onto a substrate and exposed to electron beam radiation under conditions sufficient to partially cure the dielectric layer. The exposing forms a relatively more hardened topmost portion of the dielectric layer and a relatively less hardened underlying portion of the dielectric layer.
