Description

Storage tank {STORAGE TANK}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage tank capable of preventing leakage of liquefied gas and storing liquefied gas safely and efficiently.

It should be noted that the contents described in this section merely provide background information on the present invention and do not constitute the prior art.

Due to rising oil prices and stringent environmental regulations, the use of liquefied gas, cheaper and more environmentally friendly than petroleum, is on the rise. For example, increased use of fuel for self-generation of transportation fuels such as automobiles, ships, and domestic / foreign island areas.

For example, the liquefied gas may include liquefied natural gas (LNG) or liquefied petroleum gas (LPG).

The liquefied gas is much more voluminous than gas (1/600 for LNG and 1/250 for LPG), which is convenient for storage and transportation, but the temperature is boiling (-162 ° C for LNG and -50 ° C for LPG) ) Or less.

To store such liquefied gas, a cryogenic liquefied gas storage tank is required to keep the liquefied gas below the boiling point.

Since most of the liquefied gas is at a cryogenic temperature, the liquid evaporates and vaporizes due to heat exchange with the outside, thereby generating a boil-off gas, thereby raising the pressure of the liquefied gas storage tank. The tanks are made using special materials that do not exhibit brittleness even at extremely low temperatures.

 Depending on the application of the liquefied gas storage tank, it can be divided into land / marine tanks and can be divided into pressure type or non pressure type tanks depending on whether the internal pressure is allowed or not.

In the case of pressure type tanks, they are manufactured in the form of a sphere or cylinder so as to resist the internal pressure. In the case of the non-pressure type, there is a tendency to make a box type considering space efficiency.

It is much more difficult to construct and install liquefied gas storage tanks on the sea than on land, where constraints are more constrained. Additional techniques are needed to solve these problems.

The blocking barrier 200 may be spaced apart from the tank body 100 through the barrier installation module 300 and may be spaced to surround the entire tank body 100.

Since the liquefied gas is mainly in a low temperature state, when such liquefied gas leaks, the temperature of the steel constituting the hull (S) is lowered, which may cause low-temperature brittle fracture, so that leaked liquefied gas is blocked, It is necessary to install a blocking barrier unit 200 for temporarily storing the signal until it is repaired.
