Embodiment Construction

[0027] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0028] The following liquefied gas may be LPG (liquefied petroleum gas: Liquefied Petroleum Gas), LNG, ethane, etc., and may refer to LNG (liquefied natural gas: Liquefied Natural Gas) as an example, and boil-off gas may refer to naturally gasified LNG, etc. BOG (boil off gas: Boil Off Gas).

[0029] The liquefied gas may refer to, for example, a liquid state, a gas state, a mixed state of a liquid and a gas, a supercooled state, a supercritical state, etc. regardless of a state change, and the same is true for an evaporated gas. In addition, the processing object of the present invention is not limited to liquid gas, and may be a liquefied gas processing system and / or a boil-off gas processing system.

[0030] figure 1 is a conceptual diagram of a gas treatment system according to an embodiment of the present invention.

Abstract

A ship including a gas treatment system, according to the present invention, comprises: a liquefied gas storage tank; a boil off gas compressor; a reliquefaction device for liquefying surplus boil offgas that is not supplied to a gas-requiring-place; and a control unit for providing an alarm requesting the operation of the reliquefaction device by a user, if the inner pressure of the liquefied gas storage tank reaches, within a normal pressure range, a first preset pressure or more.

Description

technical field [0001] The invention relates to a vessel comprising a gas treatment system. Background technique [0002] A ship is a means of transportation that transports a large amount of minerals, crude oil, and natural gas, or carries more than a thousand containers to sail the ocean. thrust to move. [0003] Such a ship generates thrust by driving an engine. At this time, generally, the engine uses gasoline or diesel to move a piston and the reciprocating motion of the piston rotates a crankshaft, whereby a propeller can be driven by being rotated by a shaft connected to the crankshaft. [0004] However, recently, an LNG fuel supply method that uses LNG as a fuel to drive an engine has been adopted on an LNG carrier that transports liquefied natural gas (Liquefied Natural Gas). on ships other than LNG carriers. [0005] In general, LNG is known to be a clean fuel and is also more abundant in storage than petroleum, and its usage is increasing dramatically with the ...
