Abstract
Provide floating roof arrangements. Floating roof device according to an embodiment of the present invention is a floating body for floating on the surface of the fluid stored in the tank; And a blocking part installed at an upper portion of the floating body to block contact between the fluid and the gas in the tank.
Description
The present invention relates to a floating roof arrangement applied to a fluid tank.
In general, the fluid tank refers to storing a large amount of fluid, such as LNG (Liquefied Natural Gas) or oil, and includes a marine tank and a land tank for storing the liquefied natural gas or oil, etc. do.
Since the fluid stored in the land tank is constantly evaporated from the fluid surface due to contact with the atmosphere, the fluid stored in the tank is not evaporated by using a blocking gas such as an inert gas.
However, in a marine tank that stores a large amount of fluid such as liquefied natural gas (Liquefied Natural Gas) or oil, a lot of fluid flows inside the tank by the flow of the vessel, and due to the sloshing phenomenon A free change surface is formed and a mixture of the fluid and the blocking gas may be generated in the tank, so that the actual vapor pressure (TVP) increases due to the phase equilibrium of the fluid and the blocking gas.
Therefore, the above-described method cannot be used in a marine tank in which a lot of internal flow is generated, and there is a problem in that the impact force or moment component acts on the tank and damages the structure due to the sloshing phenomenon generated by the internal flow. .
Embodiments of the present invention to provide a floating roof device that can reduce the actual vapor pressure by reducing the gas-liquid contact area while suppressing the sloshing phenomenon in the fluid storage tank.
According to an aspect of the invention, the blocking unit for blocking the contact of the gas and the liquefied gas stored in the liquefied gas storage tank for the vessel by the flow of the vessel; A floating body installed below the blocking unit, having a hemispherical shape, the inside of which is formed in a hollow shape, and having a plurality of perforations formed on a surface thereof; And a rail portion formed with a groove into which the blocking portion is inserted to move the blocking portion and the floating body vertically in the marine tank, wherein the floating body has a greater density than the blocking portion and the liquefied gas. Floating roofing devices may be provided that are made of a material having a smaller density.
The blocking portion may be arcuate.

The blocking unit may be sized to cover the fluid stored in the tank.
The roofing device can be made of a material that can withstand cryogenic temperatures and has flexibility.
