Description

선박 혼합연료공급시스템{MIXED FUEL SUPPLY SYSTEM OF SHIP}Mixed fuel supply system for ships {MIXED FUEL SUPPLY SYSTEM OF SHIP}

본 발명은 선박 혼합연료공급시스템에 관한 것이다.The present invention relates to a mixed fuel supply system for ships.

액상유기물수소운반체(LOHC, Liquid Organic Hydrogen Carrier) 기술은 액상유기물(H0-LOHC)에 수소(H2)를 결합시켜 원하는 곳으로 수송하고, 촉매를 이용하여 수소를 다시 분리한 후 액상유기물을 수소 저장 및 운반에 재사용할 수 있는 기술이다.The liquid organic hydrogen carrier (LOHC) technology combines hydrogen (H2) with liquid organic matter (H0-LOHC), transports it to a desired location, separates the hydrogen again using a catalyst, and stores the liquid organic matter as hydrogen. and reusable technology for transportation.

예컨대 10 내지 50 bar의 조건에서 촉매를 사용하면 액상유기물(H0-LOHC)과 수소(H2)가 서로 결합하여 Hx-LOHC를 형성한다. 그리고 1 내지 5 bar의 조건에서 Hx-LOHC에 열에너지 및 적절한 촉매를 가하면, 수소(H2)가 다시 방출되고 원래의 액상유기물 분자로 복귀한다. 따라서 액체 상태의 Hx-LOHC를 저장하고, 이로부터 수소를 방출시켜 수소 연료로 제공함으로써 수소연료 시스템을 안정적으로 구현할 수 있다. For example, when a catalyst is used under a condition of 10 to 50 bar, Hx-LOHC is formed by combining liquid phase organic matter (H0-LOHC) and hydrogen (H2). And when heat energy and an appropriate catalyst are applied to Hx-LOHC under the condition of 1 to 5 bar, hydrogen (H2) is released again and the original liquid organic molecules are returned. Therefore, a hydrogen fuel system can be stably implemented by storing Hx-LOHC in a liquid state and releasing hydrogen therefrom to provide hydrogen fuel.

한편, 연료가스 중에서 널리 이용되고 있는 천연가스(Natural Gas)는 메탄(Methane)을 주성분으로 하며, 통상적으로 그 부피를 1/600로 줄인 액화가스(Liquefied Gas) 상태로 변화되어 저장 및 운반되고 있다.On the other hand, natural gas, which is widely used among fuel gases, has methane as its main component, and is usually stored and transported in a state of liquefied gas with its volume reduced to 1/600. .

천연가스는 석유 연료보다 탄소 성분이 적어 탄소계 유해배기가스의 배출은 적으나, 좁은 가연 한계, 느린 연소 속도 등으로 연소가 불안정하다. 반면, 수소는 연소 속도가 빠르고 가연 한계가 넓어서 안정적으로 운전이 가능하고, 연소 반응에 의해 이산화탄소가 발생하지 않는다.Natural gas has fewer carbon components than petroleum fuel, so it emits less carbon-based harmful exhaust gases, but combustion is unstable due to a narrow combustibility limit and slow combustion speed. On the other hand, hydrogen has a fast combustion rate and a wide combustibility limit, so it can be stably operated and does not generate carbon dioxide due to a combustion reaction.

따라서, 상술한 액상유기물수소운반체 기술을 활용하여 수소 저장 및 운반을 수행하는 한편, 수소와 천연가스를 적절히 혼합하여 선박의 엔진 연료로 공급할 필요성이 제기된다.

도 1에 도시한 바와 같이 제1저장탱크(111)는 액상유기물(H0-LOHC)과 수소(H2)가 결합된 결합물을 저장한다. 액상유기물은 예컨대 벤젠 등과 같은 방향족 분자, 바이페닐과 디페닐메탄이 특정 비율로 섞여있는 액상 혼합물 등을 포함할 수 있다.As shown in FIG. 1, the first storage tank 111 stores a combination of liquid organic matter (H0-LOHC) and hydrogen (H2).

제1저장탱크(111) 내의 결합물은 로딩라인(L10)을 통해 반응기(120)로 공급된다. 로딩라인(L10)에는 펌프(P)가 마련되어, 제1저장탱크(111)로부터 공급된 결합물을 반응기(120)의 요구 조건에 맞게 가압할 수 있다.The combined material in the first storage tank 111 is supplied to the reactor 120 through the loading line L10. A pump P is provided in the loading line L10 to pressurize the combined material supplied from the first storage tank 111 according to the requirements of the reactor 120.

반응기(120)는 제1저장탱크(111)로부터 공급된 결합물을 엔진(E)의 배기가스와 열교환시켜 탈수소화 과정을 수행하여 해당 결합물을 액상유기물과 수소로 변환시킨다. The reactor 120 performs a dehydrogenation process by heat-exchanging the combined material supplied from the first storage tank 111 with the exhaust gas of the engine E, thereby converting the combined material into liquid organic matter and hydrogen.

선박 내의 엔진 행정을 거치고 하면, 대략 섭씨 150도 이상의 배기가스가 배출되는 데, 본 발명의 실시 예에서는 이러한 배기가스의 열에너지를 이용하여 결합물로부터 수소를 방출시킬 수 있다.Exhaust gas of about 150 degrees Celsius or more is discharged after passing through the engine stroke in the ship.

이때, 엔진(E)의 배기가스와 제1저장탱크(111)로부터 공급된 결합물은 반응기(120) 내의 열교환 수단에 의해 열교환되면서 탈수소화 과정을 거치게 되며, 기체 상태의 액상유기물과 수소로 변환된다. 이러한 탈수소화 과정에서 촉매가 사용될 수 있으며, 결합물로부터 수소가 방출되어 액상유기물 분자와 결합이 끊어진 상태가 된다.At this time, the combined product supplied from the exhaust gas of the engine E and the first storage tank 111 undergoes a dehydrogenation process while being heat exchanged by the heat exchange means in the reactor 120, and is converted into gaseous liquid organic matter and hydrogen. do. In this dehydrogenation process, a catalyst may be used, and hydrogen is released from the bonds, so that the bonds with liquid organic molecules are broken.

그리고 엔진(E)의 배기가스는 배기가스공급라인(L4) 상에 마련된 감압부(160)에 의해 감압된 후 반응기(120)로 보내질 수 있다. 감압부(160)는 예컨대 터보 팽창기(Turbo Expander)를 포함할 수 있다. In addition, the exhaust gas of the engine E may be sent to the reactor 120 after being reduced in pressure by the pressure reducing unit 160 provided on the exhaust gas supply line L4. The pressure reducing unit 160 may include, for example, a turbo expander.

액화부(130)는 반응기(120)에 의해 변환된 액상유기물과 수소가 혼합된 혼합물을 쿨링시켜 액상유기물을 액화시킨다. 액화부(130)는 예컨대 쿨링워터 등과 같은 냉매와 상술한 혼합물 간 열교환을 수행하여, 액상유기물을 액화시킬 수 있다.The liquefaction unit 130 liquefies the liquid organic matter by cooling the mixture of the liquid organic matter converted by the reactor 120 and hydrogen. The liquefaction unit 130 may liquefy the liquid organic matter by performing heat exchange between a refrigerant such as cooling water and the above mixture.

기액분리기(140)는 액화부(130)를 통과한 액상유기물과 수소의 혼합물을 공급받고, 액체 성분의 액상유기물과 기체 성분의 수소로 분리시킨다. 여기서, 기액분리기(140)에 의해 분리된 액체 성분의 액상유기물은 액상유기물저장라인(L3)을 통해 제2저장탱크(112)에 저장되어 수소운반체로서 다시 사용될 수 있다. 그리고, 기액분리기(140)에 의해 분리된 기체 성분의 수소는 합류라인(L2)을 통해 액화가스공급라인(L1)으로 공급된다.The gas-liquid separator 140 receives a mixture of liquid organic matter and hydrogen that has passed through the liquefaction unit 130, and separates the mixture into liquid organic matter and gaseous hydrogen. Here, the liquid organic matter of the liquid component separated by the gas-liquid separator 140 is stored in the second storage tank 112 through the liquid organic matter storage line L3 and can be used again as a hydrogen carrier. Then, the gas component hydrogen separated by the gas-liquid separator 140 is supplied to the liquefied gas supply line L1 through the confluence line L2.

액화가스공급라인(L1)은 액화가스를 저장하는 액화가스저장탱크(150)와 엔진(E)을 연결하며, 액화가스를 저장하는 액화가스저장탱크(150)의 액화가스의 증발가스를 엔진(E) 쪽으로 공급한다. The liquefied gas supply line (L1) connects the liquefied gas storage tank 150 for storing liquefied gas and the engine (E), and converts the boil-off gas of the liquefied gas in the liquefied gas storage tank 150 to the engine ( E) is supplied.

The liquefied gas may include LNG (Liquefied Natural Gas) that can be stored in a liquefied state, but is not limited thereto, and may include various types of liquefied gas that can be combined with hydrogen and supplied as fuel for an engine.

액화가스공급라인(L1)에는 엔진(E)의 요구 조건에 맞게 액화가스저장탱크(150)로부터 공급받은 액화가스의 증발가스를 압축시키는 압축기(155)가 마련될 수 있다.A compressor 155 may be provided in the liquefied gas supply line L1 to compress boil-off gas of the liquefied gas supplied from the liquefied gas storage tank 150 to meet the requirements of the engine E.

압축기(155)에 의해 압축된 증발가스는 상술한 합류라인(L2)을 통해 공급된 수소와 혼합되어 엔진(E)의 연료로 공급된다.The boil-off gas compressed by the compressor 155 is mixed with hydrogen supplied through the above-described confluence line L2 and supplied as fuel for the engine E.

이와 같이, 수소와 액화가스의 증발가스를 적절히 혼합하여 선박의 엔진 연료로 사용할 경우 운전 가능한 영역이 확장되고 유해한 배기가스 배출 감소 및 운전 성능 향상을 가져올 수 있다.In this way, when the boil-off gas of hydrogen and liquefied gas is appropriately mixed and used as engine fuel of a ship, the operable range can be expanded, harmful exhaust gas emissions can be reduced, and driving performance can be improved.

또, 엔진으로부터 방출되는 배기가스를 탈수소화 과정에 효과적으로 활용함으로써, 선박 혼합연료공급시스템(100)의 효율성 향상 및 운영비 등을 절감시킬 수 있다.In addition, by effectively utilizing the exhaust gas emitted from the engine in the dehydrogenation process, it is possible to improve the efficiency of the mixed fuel supply system 100 and reduce operating costs.

한편, 도 2를 참조하면 선박 혼합연료공급시스템(100)은 제1저장탱크(111)와 반응기(120) 사이에 마련되며, 제1저장탱크(111)로부터 공급된 결합물과 반응기(120)를 통과한 변환된 액상유기물과 수소의 혼합물 간 열교환을 수행하여, 결합물을 예열시키는 예열기(125)와, 제1저장탱크(111), 예열기(125) 및 반응기(120)를 연결하는 예열라인(L6)을 포함할 수 있다. 이때, 반응기(120), 예열기(125), 액화부(130) 및 기액분리기(140)는 분리라인(L5)에 의해 연결될 수 있다.On the other hand, referring to FIG. 2, the ship mixed fuel supply system 100 is provided between the first storage tank 111 and the reactor 120, and the combination supplied from the first storage tank 111 and the reactor 120 A preheating line connecting the preheater 125 for preheating the combined material by performing heat exchange between the mixture of hydrogen and the converted liquid organic matter passing through the first storage tank 111, the preheater 125, and the reactor 120. (L6) may be included. At this time, the reactor 120, the preheater 125, the liquefaction unit 130, and the gas-liquid separator 140 may be connected by a separation line L5.

예열라인(L11)은 제1저장탱크(111)로부터 공급된 결합물이 반응기(120)로 공급되기 이전에, 도 1에서 설명한 바와 같이 반응기(120)를 거쳐 탈수소화되어 액상유기물과 수소가 혼합된 혼합물과 열교환되어 미리 온도가 상승되도록 한다. 이를 통해 액상유기물과 수소가 혼합된 혼합물이 열에너지를 빼앗겨 온도가 상대적으로 내려가 이후의 액화부(130)에서 효과적인 액화 과정이 이루어질 수 있다. 또한 열에너지를 얻은 제1저장탱크(110)로부터 공급된 결합물은 반응기(120)에서 효과적인 탈수소화 과정이 이루어질 수 있다.In the preheating line L11, before the combined material supplied from the first storage tank 111 is supplied to the reactor 120, as described in FIG. 1, it is dehydrogenated through the reactor 120 and liquid organic matter and hydrogen are mixed. It exchanges heat with the mixture so that the temperature rises in advance. Through this, the mixture of the liquid organic matter and hydrogen is deprived of thermal energy and the temperature is relatively lowered, so that an effective liquefaction process can be performed in the liquefaction unit 130 thereafter. In addition, the combined material supplied from the first storage tank 110 obtained thermal energy may be subjected to an effective dehydrogenation process in the reactor 120.

이를 위해 예열라인(L11)은 제1저장탱크(111), 예열기(125) 및 반응기(120)를 연결하며, 제1저장탱크(111)로부터 공급된 결합물이 예열기(125)를 통과하여 온도가 상승한 후 반응기(120)로 유입되도록 한다. 이후의 과정은 도 1에서 설명되었으므로 생략한다.To this end, the preheating line (L11) connects the first storage tank 111, the preheater 125, and the reactor 120, and the combination supplied from the first storage tank 111 passes through the preheater 125 to reach a temperature After rising, it is introduced into the reactor 120. Subsequent processes are omitted because they have been described in FIG. 1 .
