    PURPOSE: An LNG(Liquefied Natural Gas) carriage tank is provided to load and carry a container in a container carrier after installing an LNG storage tank and an insulating equipment inside the container. CONSTITUTION: An LNG storage tank(20) is installed by separating from the inner wall of a container. A cooling device(30) maintains the LNG storage tank under a certain temperature. A support(40) connects the LNG storage tank with the inner wall of the container. An insulating material(50) is installed inside the container. By installing an LNG carriage tank and an insulating material inside the container, the LNG carriage tank is carried by a container carrier instead of an exclusive LNG carrier.

    Container type LNG tank {Container type LNG tank}
    [7] The present invention relates to a LNG transport method, and more particularly, a container type LNG transport tank in which an LNG storage tank is embedded inside a general freight transport container and then loaded on a container transport ship to transport LNG even in a general container transport ship. It is about.
    [8] LNG is a colorless, transparent, cryogenic liquid that cools methane-based natural gas to minus 162 degrees and reduces its volume to one-hundredth by mass, commonly referred to as liquefied natural gas.
    [9] As LNG emerged as an energy resource, an efficient transportation method that can transport large quantities from the production base to the destination of the demand site was considered to use this gas as energy, and the result was the LNG carrier for the maritime transportation of LNG. appear.
    [10] Natural gas is liquefied to cryogenic conditions, and LNG storage tanks are built on large vessels for the storage and transportation of LNG, which is used as a major energy source. LNG carriers design and design tanks that can withstand ultra low temperatures of minus 162 degrees. As it needs to be built, the highest level of drying technology is needed for the entire shipbuilding industry.
    [11] LNG storage tank manufacturing technology, the most distinctive form of LNG carriers, is limited to Moss and Membrane types depending on the type of ship being built in some developed countries. Not only was there an irrational point that the drying method was selected, but there was also a problem of high production costs,
    [12] In addition, the technology of the LNG storage tank, which has to maintain a very large volume, accurate specific gravity and cryogenic temperature, is limited to only a limited type, and the technology has been closed.
    [13] LNG carriers are liquefied mined natural gas (LNG) at low temperatures and then transported to the required place. Because natural gas is liquefied at low temperatures, natural gas must be continuously cooled during transportation, thus requiring heat insulation from the outside. Therefore, transportation is possible only when using a dedicated carrier provided with a natural gas liquefaction facility and an insulation facility.
    [14] In case of LNG carriers, a natural gas liquefaction facility and a thermal insulation facility are essential, which results in a long production period and a high production cost. Therefore, when the LNG consumption is increased, such as the winter period, there was a problem that can not transport the amount required by the existing transport capacity alone.
    [15] In addition, the transported LNG must build a dedicated storage facility onshore for storage. However, LNG storage facilities, like LNG carriers, have long construction periods and high manufacturing costs, making it difficult to expand the LNG supply and demand.
    [16] In order to solve the above-mentioned problems, an object of the present invention is to provide a container-type LNG transport tank that can be carried by loading the container on the container carrier after installing the LNG storage tank and the insulation facility inside the container for cargo transportation. It is done.
    [17] In order to achieve the above object, the present invention provides a container for cargo transportation, the LNG storage tank spaced apart from the inner wall of the container, a cooling device for maintaining the LNG storage tank below a predetermined temperature, the LNG storage tank and the container inner wall Consists of a support to connect the.

    [18] EMBODIMENT OF THE INVENTION Hereinafter, with reference to an accompanying drawing, the structure and working state of this invention are demonstrated.
    [19] 2 is a cross-sectional view showing the configuration of an embodiment of a container-type LNG transport tank according to the present invention, in a freight transport container, an LNG storage tank 20 spaced apart from an inner wall of the container, and the LNG storage tank 20. It is characterized by consisting of a cooling device 30 for maintaining the temperature below a predetermined temperature, the support 40 for connecting the LNG storage tank 20 and the container inner wall.
    [20] Hereinafter, the present invention will be described with reference to the drawings.
    [21] The LNG storage tank 20 is installed inside the freight transport container to manufacture the LNG transport container 10. At this time, the storage tank 20 to be installed may be the same as a gas storage tank for vehicle transportation, or may be manufactured separately for the container. In any case, a space must be formed between the LNG storage tank 20 and the inner wall of the container, and the inner wall of the storage tank 20 and the container 10 so that the storage tank 20 does not move by an externally applied vibration. Install the support 40 so that it can be fixed by connecting. The support 40 is also connected to each storage tank 20 installed in the container 10.
    [22] Since the gas storage tank must be maintained at a constant temperature, it is necessary to attach the cooling device 30 to the container. Power used in the cooling device 30 is to be supplied from the outside.
    [23] Insulating material 50 to block the movement of heat in the space between the LNG storage tank 20 and the inner wall of the container 10 to be installed. Since the liquefaction temperature of LNG is very low, the heat insulating material 50 should be installed to prevent external heat from invading. In addition to the function of the heat insulating material which blocks heat transfer, the heat insulating material also serves as a buffer for absorbing external shocks. .
    [24] As the heat insulating material installed inside the container, it is preferable to use a lightweight material such as styrofoam.
    [25] When the present invention is completed, the same method as the general container handling method is used when loading the container carrier and unloading and storing the loaded container.
    [26] According to the present invention as described above, by installing the LNG transport tank inside the cargo transport container and by installing a cooling device and heat insulator to move to the container carrier instead of the LNG carrier, the LNG carrier by the surge of LNG demand In case of shortages, LNG carriers can be transported by container cargo ships. In addition, when the LNG storage facility is full, it can be stored in the same way as general container storage, so there is no need to install a separate storage facility.
