Description

FUEL GAS SUPPLY SYSTEM [0002]

The present invention relates to a fuel gas supply system.

As IMO regulations on the emission of greenhouse gases and various air pollutants are strengthened, shipbuilding and marine industries are replacing the use of heavy fuel oil and diesel oil, In many cases.

Natural gas, which is widely used in fuel gas, is mainly stored as methane and is stored and transported in a liquefied gas state where the volume thereof is reduced to 1/600.

The ship carrying the liquefied gas has a storage tank which is insulated to store the liquefied gas. In addition, such a vessel can provide a fuel gas supply system that vaporizes naturally occurring boiling off gas in the storage tank or liquefied gas in the storage tank and supplies it to the fuel of the engine. The engine of the ship is equipped with a low-pressure (about 5-8 bar) injection engine such as a DFDE (Dual Fuel Disel Electric) engine, a high-pressure (about 150-700 bar) injection engine such as the ME-GI engine (Man B & W's Gas Injection engine) A medium pressure gas injection engine capable of combusting with medium pressure (about 16-18 bar) fuel gas may be used.

The above-described fuel gas supply system can compress the evaporated gas supplied from the storage tank by the compression unit and supply it to the fuel of the ME-GI engine. At this time, when more evaporation gas than the fuel consumption amount required by the engine is supplied, the surplus evaporation gas is heat-exchanged with the evaporation gas supplied from the storage tank by the heat exchanger and is liquefied, and then supplied to the gas-liquid separator. The gas-liquid separator separates the evaporated gas of the excess heat-exchanged gas into gas and liquid components. The liquid component separated by the gas-liquid separator is stored in the storage tank, and the gas component is mixed with the evaporation gas supplied from the storage tank and then circulated again.

However, since the gas component separated by the gas-liquid separator contains a large amount of nitrogen components, it is possible to increase the processing capacity of the compression section and accordingly the energy consumption, and the liquefaction efficiency of the heat exchange section can be lowered. As a related art, refer to Korean Patent Laid-Open No. 10-2014-0052898 (published on May 31, 2014).

[

The above-described storage tank 101 may include a membrane type tank, an SPB type tank, and the like, which store the fuel in a liquefied state while maintaining an adiabatic state. The liquefied gas stored in the storage tank 101 may be any one of Liquefied Natural Gas (LNG), Liquefied Petroleum Gas (LPG), Dimethylether (DME), and Ethane which can be stored in a liquefied state, but is not limited thereto .

The internal pressure of the storage tank 101 may be maintained at 1 bar when the liquefied gas to be stored is LNG, or may be maintained at a pressure higher than the 1 bar considering the fuel supply conditions. The internal temperature of the storage tank 101 may be maintained at about -163 DEG C to maintain the liquefied state of the LNG. The evaporated gas of the liquefied gas stored in the storage tank 101 is supplied to the first engine E1 through the heat exchange unit 120 and the compression unit 110 via the first supply line L1.

The compression unit 110 may be configured to include a plurality of alternately arranged compressors 111 and a cooler 112 and may supply the evaporated gas of the liquefied gas supplied from the storage tank 101 to the first engine E1 And is compressed to meet the fuel gas supply conditions. The first engine E1 may be, for example, a high pressure gas injection engine such as an ME-GI engine (Gas Injection engine manufactured by Man B & W). When more compressed evaporative gas than the fuel consumption required by the first engine E1 is supplied, the surplus compressed evaporative gas flows into the refill line L2.

The evaporated gas compressed by the compression unit 110 may be supplied to the heat exchange unit 120 while being depressurized by the first control valve V1. Thus, the liquefaction efficiency can be improved.

The evaporated gas liquefied by the heat exchange unit 120 may be supplied to the gas-liquid separator 130 while being depressurized by the second control valve V2.

The above-mentioned mixture is composed of a first gas containing a relatively high concentration of nitrogen separated by the filter 150 and a gas component separated by the second gas-liquid separator 160. This mixture is supplied to the second engine E2 through the second supply line L12 in accordance with the fuel consumption of the second engine E2, and the excess mixture is circulated through the refrigerant circulation line L11.

At this time, the expanded mixture passing through the refrigerant inflator 166 can transfer the cold heat from the heat exchanging unit 120, and the liquefaction efficiency of the heat exchanging unit 120 can be increased through this. The second engine E2 may be a low pressure (about 5-8 bar) injection engine such as a Dual Fuel Disel Electric (DFDE) engine or the like.

The filter 150 separates the gas component separated by the first gas-liquid separator 130 into a first gas containing a high concentration nitrogen component and a second gas mainly containing a methane component relatively. The gas component separated by the first gas-liquid separator 130 contains a large amount of nitrogen.

The first gas separated by the filter 150 is supplied to the refrigerant circulation line L11 through the first gas supply line L5 and the second gas is supplied to the recovery line L7 via the heat exchange unit 120, And stored in the storage tank 101.

At this time, the second gas containing a relatively low concentration of nitrogen is stored in the storage tank 101 together with the liquid component of the second gas-liquid separator 140, and is circulated again. Accordingly, it is possible to reduce the processing capacity of the compression unit 110 and thus the energy consumption, thereby improving the efficiency of operation. In addition, the liquefaction performance of the heat exchanging unit 120 can be improved.

The foregoing has shown and described specific embodiments.
