摘要： The present invention relates to an apparatus for reducing greenhouse gas emission in a vessel and a vessel including the same, in which CO2 absorbed by taking only a part of the absorbent liquid used when collecting CO2 is removed, so that the device sizes of an absorbent liquid recycling unit and an absorbent liquid circulating unit is kept small and continuous operation is enabled. Or in which exhaust gas is cooled by a heat exchange method, thereby preventing the decrease in a concentration of an absorbent liquid, and CO2 absorbed by taking only a part of the absorbent liquid used when collecting CO2 is removed and an unreacted absorbent liquid is continuously circulated, thereby enabling continuous operation.

摘要： Disclosed is a membrane bonding structure for bonding a membrane for forming a sealed wall between first and second surfaces of a storage tank for storing liquefied gas. The membrane bonding structure may comprise: a planar portion panel installed on the first and second surfaces so as to thermally insulate the storage tank; a bonding panel installed on the boundary portion between the first and second surfaces together with the planar portion panel; a first membrane attached to the planar portion panel on the first surface and to the bonding panel so as to seal the storage tank; and a second membrane attached to the planar portion panel on the second surface and to the bonding panel so as to seal the storage tank. The first membrane and the second membrane may be attached to the bonding panel so as to make no direct connection.

摘要： 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.
