| 20090249798 | APPARATUS AND METHOD FOR INCREASING EFFICIENCY OF A GAS TURBINE AND A MARINE STRUCTURE HAVING THE SAME - 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. | 10-08-2009 |
| 20090249799 | APPARATUS AND METHOD FOR INCREASING EFFICIENCY OF A GAS TURBINE AND A MARINE STRUCTURE HAVING THE SAME - 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. | 10-08-2009 |
| 20090259081 | METHOD AND SYSTEM FOR REDUCING HEATING VALUE OF NATURAL GAS - Disclosed is a system for reducing a heating value of natural gas. The system includes a heat exchanger to liquefy a portion of components having high heating values, a gas-liquid separator to separate the liquefied component, and a nitrogen adding mechanism to add nitrogen to remaining non-liquefied components. The system includes an additional heat exchanger to cool and liquefy the remaining non-liquefied components after the gas-liquid separator separates the liquefied component from the natural gas. The heat exchangers employ cold heat generated upon regasification of LNG. The system can reduce the heating value of natural gas composed of a variety of hydrocarbon components according to requirements of a place of demand by separating the component with the higher heating value from the natural gas to allow the separated component to be used as fuel, thereby reducing an overall size and operating costs of the system. | 10-15-2009 |
