The present invention relates to a liquefied fuel power generation and distribution system, and a loading and unloading method using the system, and more specifically, to generate electricity by using LNG as fuel in a power generation system mounted on an upper part of a floating structure. Cooling the inside of the refrigeration container mounted on the upper part of the floating structure by using the vaporization heat generated when the LNG is regasified, and configured to use the heat generated in the process of cooling the inside of the refrigeration container as a LNG regasification heat source, Container loading and unloading is to save energy by recycling waste energy by using cargo ships entering the loading dock of refrigerated containers through connecting lamps connecting floating structures and land, or by using cargo ships mooring the side of floating structures. And of course, liquefied fuel generation and water to improve the logistics utilization of refrigerated containers It relates to a system and method for handling input the system.

Recently, the interest in power generation using natural gas has increased due to the demand for environmentally friendly power generation.

In particular, with the emergence of a combined cycle power generation technology that recovers waste heat and drives a steam turbine, demand for gas power generation is increasing due to increased efficiency of gas power generation and stabilization of gas prices.

There is a growing interest in gas power generation in emerging developing countries where power supply is not smooth, and gas power generation has many limitations because development is possible only when gas infrastructure such as gas storage is provided on land.

In order to solve this problem, a floating offshore gas storage regasification plant line called Floating Storage Re-gasfication Unit (FSRU) has emerged, and the offshore gas storage regasification plant line is used to supply gas to land power plants. Was done.

However, such land-based power generation using FSRUs creates a double burden of installing FSRUs at sea and building power plants on land. That is, as well as the FSRU, there is a disadvantage that it takes place and secures the construction cost according to the construction of the land power plant. In particular, it takes a lot of time to build a land power plant, it is difficult to perform the power supply in a short time.

Therefore, in addition to the above-described method, research on a new and advanced type of floating and storage power plant (FSPP) capable of generating electricity by using waste heat while having a gas reservoir at sea has been actively conducted. .

On the other hand, the vessel is provided with a refrigerated container for refrigeration and freezing storage of agricultural products, fish products, meat and the like.

Refrigerated container (Reefer container) is used to transport cargo that must maintain a constant temperature during transportation, such as refrigerated and refrigerated cargo in a container ship, the refrigerated container is able to maintain the temperature inside -30 ℃ ~ 30 ℃ It is equipped with a refrigeration system and is insulated.

The refrigerated container loaded on the container ship operates a separate refrigeration system to control the temperature from about -26 ℃ to 26 ℃, and to continue to supply a separate power to continue cooling during transportation.

In such a refrigeration system, the refrigerant compressed in the compressor supplies cold air to the container box over each part, and a separate air-con system is provided for cooling the ship's residence. It is installed at the to supply cold air. In this case, the refrigeration container uses a refrigeration cycle that generates cool air in a predetermined path, that is, compression, condensation, expansion, and evaporation.

A brief description of such a refrigeration cycle includes a compressor for compressing a refrigerant and discharging it into a liquid state at a high temperature and high pressure, a condensation unit for exchanging the compressed refrigerant with an outside air (heat release) to a state of high temperature and high pressure, and condensing An expansion valve for adiabatic expansion of the refrigerant to phase change into a low-temperature low-pressure gas state, and an evaporation unit for exchanging the low-temperature low-pressure gaseous refrigerant with an outside air and sending it back to the compressor in a low-temperature low-pressure state.

However, the conventional container ship refrigeration system has to supply a lot of power to the refrigerator attached to the refrigeration container itself, there is a problem to install a separate additional generator, the cost burden and oil cost burden due to the additional installation of the generator There is a problem.

In addition, the conventional refrigeration system is to use a generator running on heavy oil (HFO), there is a problem that causes environmental pollution by discharging pollutants such as SOx, NOx, CO ₂ and fine dust.

In addition, in the related art, since complicated mechanical equipment such as a refrigerator is installed in the container itself, there is a problem that a high risk of damage to the refrigerated container during container loading and unloading is excessively consumed.

In the case of a conventional LNG fuel propulsion container ship, there is a problem that energy efficiency is lowered by directly consuming cryogenic energy of boil gas (BOG) naturally occurring in a fuel tank as fuel of an engine or a boiler without a separate process.

In addition, the conventional refrigeration system has a risk of leaking in the process of forcibly compressing and expanding the refrigerant through the refrigerator, such a refrigerant is a material that destroys the global ozone layer, causing a problem of global warming.

As is well known, since the liquefaction temperature of LNG is cryogenic at atmospheric pressure of -163 ° C, the LNG evaporates even if the temperature is only slightly higher than the atmospheric pressure of -163 ° C.

Since external heat is transferred to the LNG tank during ship operation, LNG is vaporized in the LNG tank to continuously generate boil-off gas (BOG).

A fuel supply line is connected to the upper portion of the LNG tank, and the boil-off gas generated in the LNG tank is compressed in the compressor and then supplied to the power generation system.

Normally, only the boil-off gas generated in the LNG tank is insufficient for the amount of fuel gas required in the power generation system. Therefore, in order to compensate for the insufficient fuel gas, the LNG is removed from the LNG tank, vaporized in a vaporizer, compressed by a compressor, and then Will be supplied.

The carburetor is disposed in the fuel supply unit, and serves to vaporize the liquefied gas. In the vaporizer, a heat source for vaporizing the liquefied gas is required at this time.

Conventionally, seawater is used as a heat source for vaporization of liquefied gas, but when the seawater cooled by liquefied gas and heat is discharged to the sea as it is, it causes the marine ecosystem to be destroyed by the temperature difference with the surrounding seawater. It causes environmental problems.

In addition, when the sea water is just discharged into the sea, the cold heat energy absorbed in the process of heat exchange with the liquefied gas is not used where necessary, and is discarded into the sea. In addition, even when a glycol solution is used as a heat source to prevent freezing in the vaporizer, seawater is usually used to increase the temperature of the glycol solution cooled by heat exchange with liquefied gas, which in this case also results in the same result. do.
