Ｆ―Ｔ 고정층 반응기 온도조절 장치{Temperature Control Device For A Fischer-Tropsch Fixed-Bed Reactor}FT-T Fixed Bed Reactor Temperature Controller {Temperature Control Device For A Fischer-Tropsch Fixed-Bed Reactor}

본 발명은 F-T 고정층 반응기 내부 온도를 일정하게 유지하여 코발트-촉매와 합성가스의 반응을 촉진시켜 생성되는 합성연료의 선택도를 높일 수 있는 구조의 F-T 고정층 반응기 온도조절 장치에 관한 것이다.The present invention relates to an F-T fixed bed reactor temperature control apparatus having a structure capable of increasing the selectivity of the synthetic fuel produced by maintaining a constant temperature inside the F-T fixed bed reactor to promote the reaction of cobalt-catalyst and syngas.

일반적으로, 메탄가스를 주원료로 하는 천연가스를 이용하여 개질공정-->액화공정을 통해 최종적으로 가솔린, 디젤, 왁스 등의 합성연료를 제조하여 천연가스 원료로 사용하여 액체 연료를 생산할 수 있도록 하는 것이 천연가스 액화 시스템이다.In general, the synthetic gas such as gasoline, diesel, and wax is finally produced through the reforming process-> liquefaction process using natural gas mainly composed of methane gas, and used as natural gas raw material to produce liquid fuel. It is a natural gas liquefaction system.

여기서 개질공정은 천연가스를 수소와 일산화탄소를 주로 포함하는 합성가스(H2와 CO의 비=2)로 변환하는 공정이다.Here, the reforming process is a process of converting natural gas into a synthesis gas (a ratio of H 2 and CO = 2) mainly containing hydrogen and carbon monoxide.

마지막에서 액화공정은 합성가스를 촉매 상에서 반응시켜 액상 합성연료로 변환하는 공정이다.Finally, the liquefaction process is a process of converting syngas to a liquid synthetic fuel by reacting it on a catalyst.

상기에서 액화공정을 수행하기 위해서는 상기 F-T 고정층 반응기로 합성가스 유입시켜 F-T 고정층 반응기의 촉매파이프에 저장된 코발트-촉매와 반응하도록 하여 합성연료를 생성한다. In order to perform the liquefaction process, the synthesis gas is introduced into the F-T fixed bed reactor to react with the cobalt-catalyst stored in the catalyst pipe of the F-T fixed bed reactor to generate synthetic fuel.

이러한 F-T 고정층 반응기는 촉매파이프의 내부에서 합성가스(CO + H2)와, 코발트(Co)-촉매가 반응하면 합성연료가 생성된다.The FT fixed bed reactor generates synthetic fuel when the synthesis gas (CO + H 2 ) and the cobalt (Co) -catalyst react inside the catalyst pipe.

이 때 반응 초기에는 합성가스와 코발트-촉매의 반응을 촉진시키기 위해 F-T 고정층 반응기 내 온도를 일정 반응온도까지 상승시켜야 한다.At this time, the temperature in the F-T fixed bed reactor must be raised to a certain reaction temperature in order to promote the reaction of the syngas and the cobalt catalyst.

이 후 합성가스와 코발트-촉매가 반응이 시작되면 심한 발열 반응에 의해 F-T 고정층 반응기 내 온도는 급격히 상승하게 되어 메탄가스와 이산화탄소의 발생이 증가되며, 이에 따라 합성연료의 선택도를 저하시킨다.Afterwards, when the synthesis gas and the cobalt-catalyst are reacted, the temperature in the F-T fixed bed reactor increases rapidly due to a severe exothermic reaction, thereby increasing the generation of methane gas and carbon dioxide, thereby decreasing the selectivity of the synthetic fuel.

따라서 상기 F-T 고정층 반응기의 내부 온도는 반응 전, 반응 시, 반응 후가 일정하게 유지하는 것이 선행되어야 한다.Therefore, the internal temperature of the F-T fixed bed reactor should be preceded by maintaining a constant before and after the reaction.

하지만 종래에는 F-T 고정층 반응기 내부의 온도를 효율적으로 조절할 수 있는 장치가 없어 합성연료의 생산이 저하되는 문제점이 있었다.However, in the related art, there is a problem in that the production of synthetic fuel is reduced because there is no device that can efficiently control the temperature inside the F-T fixed bed reactor.

본 발명은 상기와 같은 문제점을 감안하여 안출된 것으로, 본 발명의 목적은, F-T 고정층 반응기 내부 온도를 일정하게 유지하여 코발트-촉매와 합성가스의 반응을 촉진시켜 생성되는 합성연료의 선택도와 생산량을 높일 수 있는 구조의 F-T 고정층 반응기 온도조절 장치를 제공하는데 있다.The present invention has been made in view of the above problems, and an object of the present invention is to maintain a constant internal temperature of the FT fixed bed reactor to promote the reaction between cobalt-catalyst and syngas, and to select the amount and the amount of synthetic fuel produced. It is to provide a FT fixed bed reactor temperature control device having a high structure.

더 나아가 본 발명의 목적은, 천연가스에서 개질공정을 통해 변환된 합성가스를 공급받아 촉매파이프 내의 코발트-촉매와 반응시켜 합성연료를 생성하는 F-T 고정층 반응기에 있어서, 상기 F-T 고정층 반응기 내부에 다수의 촉매파이프를 고정할 수 있도록 상부 및 하부에 개재되는 상/하부격판과, 상기 상/하부격판을 통해 F-T 고정층 반응기 내부에 순차적으로 형성되는 합성가스유입공간부, 촉매파이프고정공간부 및 합성연료회수공간부와, 외부에서 상기 촉매파이프고정공간부와 상통되도록 연결되어, 합성가스가 촉매파이프 내의 코발트-촉매와 반응하도록 반응온도까지 촉매파이프를 가열하는 히팅부와, 상기 촉매파이프와 근접되도록 촉매파이프고 정공간부에 설치되어 합성가스가 코발트-촉매와 반응시 촉매파이프의 급격한 온도 상승을 방지할 수 있도록 냉각수를 분사하여 촉매파이프를 냉각하는 냉각부를 포함하여 이루어지는 것을 특징으로 하는 F-T 고정층 반응기 온도조절 장치를 제공하는데 있다.Furthermore, an object of the present invention, in the FT fixed bed reactor for producing a synthetic fuel by receiving the synthesis gas converted through the reforming process in natural gas and cobalt-catalyst in the catalyst pipe, a plurality of inside the FT fixed bed reactor Upper and lower plates interposed between the upper and lower plates so as to fix the catalyst pipe, and the synthesis gas inlet space portion, the catalyst pipe fixed space portion, and the synthetic fuel recovery which are sequentially formed inside the FT fixed bed reactor through the upper and lower partition plates. A space part connected to the catalyst pipe fixed space part from the outside, and a heating part for heating the catalyst pipe to the reaction temperature so that the synthesis gas reacts with the cobalt-catalyst in the catalyst pipe, and the catalyst pipe so as to be close to the catalyst pipe.

It is to provide a F-T fixed bed reactor temperature control device comprising a cooling unit for cooling the catalyst pipe by spraying the cooling water to be able to.

본 발명에 따른 F-T 고정층 반응기 온도조절 장치에 따르면, 실시간으로 촉매파이프 내부 온도를 측정하여 히팅부와 냉각부를 제어하여 촉매파이프의 내부온도를 조절함은 물론 반응기 내부의 열로 인해 냉각관에서 증발되는 냉각수는 스팀형태로 배출되어 별도의 에너지원으로 사용이 가능하고, 더불어 에너지 소비가 작은 장점이 있다.According to the FT fixed bed reactor temperature control apparatus according to the present invention, by measuring the temperature inside the catalyst pipe in real time to control the heating unit and the cooling unit to adjust the internal temperature of the catalyst pipe as well as the cooling water evaporated in the cooling tube due to the heat inside the reactor It is discharged in the form of steam can be used as a separate energy source, and also has the advantage of low energy consumption.

또한 F-T 고정층 반응기 내부의 온도를 일정하게 유지하여 메탄가스와 이산화탄소의 발생을 최소화하고, 생산되는 합성연료의 선택도를 증가시킬 수 있는 장점이 있다.In addition, by maintaining a constant temperature inside the F-T fixed bed reactor to minimize the generation of methane gas and carbon dioxide, there is an advantage that can increase the selectivity of the synthetic fuel produced.

이러한 F-T 고정층 반응기 온도조절 장치(100)는 크게 2부분으로 구성되는데, 이는 F-T 고정층 반응기(10)의 내부에 설치되는 히팅부(30)와 냉각부(40)로 구성된다.The F-T fixed bed reactor temperature control device 100 is largely composed of two parts, which consists of a heating unit 30 and a cooling unit 40 installed inside the F-T fixed bed reactor 10.

여기서 상기 F-T 고정층 반응기(10)는 내부에 다수 설치되는 촉매파이프(70)를 고정할 수 있도록 상부 및 하부에 상/하부격판(11,12)이 개재되어 있는 구성이다. 이 때 상기 촉매파이프(70)는 F-T 고정층 반응기(10)의 단면적 전체에 걸쳐 균일하게 설치되는 구조이다.(도 2에 도시)In this case, the F-T fixed bed reactor 10 is configured to have upper and lower plates 11 and 12 interposed therebetween so as to fix a plurality of catalyst pipes 70 installed therein. At this time, the catalyst pipe 70 is a structure that is uniformly installed over the entire cross-sectional area of the F-T fixed bed reactor 10 (shown in Figure 2).

아울러 상기 촉매파이프(70)는 양단에 망체가 결합되어 있어, 합성가스의 유입과 더불어 합성가스가 코발트-촉매와 반응 후 생성되는 합성연료가 배출될 수 있도록 구성된다.In addition, the catalyst pipe 70 has a mesh connected to both ends thereof, and is configured to allow the synthesis fuel generated after the synthesis gas reacts with the cobalt-catalyst with the introduction of the synthesis gas to be discharged.

그리고 상기 상/하부격판(11,12)을 통해 F-T 고정층 반응기(10) 내부에 순차적으로 합성가스유입공간부(21), 촉매파이프고정공간부(22) 및 합성연료회수공간부(23)가 형성되는 구조이다.In addition, the synthesis gas inflow space 21, the catalyst pipe fixed space 22, and the synthetic fuel recovery space 23 are sequentially in the FT fixed bed reactor 10 through the upper and lower plates 11 and 12. It is a structure to be formed.

아울러 상기 히팅부(30)는 외부에서 상기 촉매파이프고정공간부(22)와 상통 되도록 연결되어, 합성가스가 촉매파이프(70) 내의 코발트-촉매와 반응하도록 반응온도까지 촉매파이프(70)를 가열하는 기능을 한다.In addition, the heating unit 30 is connected to the outside of the catalyst pipe fixed space 22 from the outside, heating the catalyst pipe 70 to the reaction temperature so that the synthesis gas reacts with the cobalt-catalyst in the catalyst pipe 70 Function.

이러한 히팅부(30)는 히터(31)와, 블로워팬(32)으로 구성되어 촉매파이프(70)를 가열할 수 있도록 상기 촉매파이프고정공간부(22)에 열풍을 공급하는 구조이다.The heating unit 30 is configured of a heater 31 and a blower fan 32 to supply hot air to the catalyst pipe fixing space 22 to heat the catalyst pipe 70.

이 때 상기 F-T 고정층 반응기(10)의 내부에 유입된 열풍은 열풍배출구(13)를 통해 외부로 유출된다.At this time, the hot air introduced into the F-T fixed bed reactor 10 flows out through the hot air outlet 13.

아울러 냉각부(40)는 촉매파이프(70)의 외주면에 근접되도록 촉매파이프고정공간부(22)에 다수 설치되는 구조이다.In addition, the cooling unit 40 is a structure that is installed in the plurality of catalyst pipe fixed space 22 so as to be close to the outer peripheral surface of the catalyst pipe (70).

이러한 냉각부(40)는 합성가스가 코발트-촉매와 반응시 촉매파이프(70)의 급격한 온도 상승을 방지할 수 있도록 촉매파이프(70)를 냉각하는 기능을 한다.The cooling unit 40 functions to cool the catalyst pipe 70 to prevent a sudden temperature rise of the catalyst pipe 70 when the syngas reacts with the cobalt-catalyst.

여기서 상기 냉각부(40)는 상기 각 촉매파이프(70)의 둘레에 일정간격을 두고 설치되는 다수의 냉각수분사관(41)으로 이루어진다.(도 2에 도시)Here, the cooling unit 40 is composed of a plurality of cooling water injection pipe 41 is installed at a predetermined interval around the respective catalyst pipes 70 (shown in Figure 2).

상기 냉각수분사관(41)은 외주면에 다수의 상기 분사구(411)가 형성되되, 상기 분사구(411)는 냉각수가 넓은 범위로 분포되어 분사될 수 있도록 내측에서 외측으로 갈수록 직경이 넓어지는 구조이다.The cooling water injection pipe 41 has a plurality of injection holes 411 are formed on the outer circumferential surface, the injection hole 411 is a structure that the diameter from the inner side to the outer side so that the cooling water is distributed in a wide range to be injected.

한편 냉각부(40)는 냉각수의 압력조절과 송출 여부를 제어할 수 있는 밸브(412)가 냉각수분사관에 더 연결되는 구조이다.On the other hand, the cooling unit 40 has a structure in which a valve 412 capable of controlling the pressure control and delivery of the cooling water is further connected to the cooling water injection pipe.

아울러 F-T 고정층 반응기 온도조절 장치(100)는 촉매파이프(70)의 내부에 다수의 온도센서(50)가 구비되며, 상기 온도센서(50)를 통해 밸브(412), 히팅 부(30) 및 냉각부(40)의 가동을 제어하는 제어부(60)가 구비되는 구조이다.(도 3에 도시)In addition, the FT fixed bed reactor temperature control device 100 is provided with a plurality of temperature sensors 50 inside the catalyst pipe 70, the valve 412, the heating unit 30 and the cooling through the temperature sensor 50 It is a structure provided with the control part 60 which controls the operation of the part 40. (shown in FIG. 3).

이하에서는 본 발명에 따른 F-T 고정층 반응기 온도조절 장치의 작동에 관하여 첨부되어진 도면과 함께 더불어 간단히 설명하기로 한다.Hereinafter, the operation of the F-T fixed bed reactor temperature control device according to the present invention will be briefly described together with the accompanying drawings.

도 4는 본 발명에 따른 F-T 고정층 반응기 온도조절 장치의 제 1작동도 및 도 5는 본 발명에 따른 F-T 고정층 반응기 온도조절 장치의 제 2작동도이다.4 is a first operation of the F-T fixed bed reactor temperature control apparatus according to the present invention and Figure 5 is a second operation of the F-T fixed bed reactor temperature control apparatus according to the present invention.

먼저 도 4에 도시된 바와 같이, 히팅부(30)의 히터(31)와 블로워팬(32)을 가동시켜 합성가스와 촉매가 반응될 수 있는 온도 요건을 충족될 때까지 촉매파이프고정공간부(22)로 열풍을 공급한다.First, as shown in FIG. 4, the heater pipe 31 and the blower fan 32 of the heating unit 30 are operated so that the catalyst pipe fixed space portion (s) is maintained until the temperature requirement for syngas and the catalyst can be reacted ( 22) to supply hot air.

이와 동시에 촉매파이프 내부에 비활성가스인 질소가스를 공급하여 온도상승에 의한 촉매의 성질이 변화되지 않도록 한다.At the same time, nitrogen gas as an inert gas is supplied into the catalyst pipe so that the properties of the catalyst are not changed due to the temperature rise.

그리고 열풍공급에 따라 반응온도가 충족되는 온도 요건인 200 ~ 350℃되면 감지되는 온도센서(50)의 센싱값에 따라 제어부(60)가 히터(31)와 블로워팬(32)의 가동을 조절하여 열풍량을 조절한다.The controller 60 controls the operation of the heater 31 and the blower fan 32 according to the sensing value of the temperature sensor 50, which is detected when the reaction temperature is 200 to 350 ° C. according to the hot air supply. Adjust the hot air volume.

이 후 합성가스를 F-T 고정층 반응기(10)의 합성가스유입공간부(21)로 유입시킨다.Thereafter, the synthesis gas is introduced into the synthesis gas inflow space 21 of the F-T fixed bed reactor 10.

합성가스유입공간부(21)로 유입된 합성가스는 다수의 촉매파이프(70)의 내부로 유입된다.Syngas introduced into the synthesis gas inflow space 21 is introduced into the plurality of catalyst pipes 70.

그러면 촉매파이프(70)의 내부에 저장된 촉매와 합성가스가 반응하게 된다.Then, the catalyst and the synthesis gas stored in the catalyst pipe 70 react.

이 때 촉매파이프(70)는 합성가스(CO + H2)와, 코발트(Fe)-촉매가 반응에 의한 발열 때문에 촉매파이프(70)의 온도가 350℃ 이상으로 급격히 상승하게 된다.At this time, the temperature of the catalyst pipe 70 rapidly rises to 350 ° C. or higher due to the exothermic reaction between the synthesis gas (CO + H 2 ) and the cobalt (Fe) -catalyst.

여기서 촉매파이프(70) 내 온도는 대략 200 ~ 350℃ 정도의 범위 내에서 일정하게 유지되어야 하는데, 그렇지 못하면 메탄가스와 이산화탄소의 발생이 증가되어 합성연료의 선택도를 저하시킨다.Here, the temperature in the catalyst pipe 70 should be kept constant within the range of about 200 ~ 350 ℃, otherwise the generation of methane gas and carbon dioxide is increased to reduce the selectivity of the synthetic fuel.

따라서 F-T 고정층 반응기(10) 내 온도를 어느 정도 냉각하여 일정하게 유지시켜야할 필요가 있으며, 이는 냉각부(40)을 통해 가능하다.Therefore, it is necessary to cool the temperature in the F-T fixed bed reactor 10 to a certain degree and keep it constant, which is possible through the cooling unit 40.

이러한 냉각 과정은 먼저, 도 5와 같이, 냉각수가 냉각수분사관(41)을 통해 F-T 고정층 반응기(10)의 내부로 송출되기 전에 밸브(412)를 거치게 되는데, 상기 밸브(412)를 통해 냉각수의 압력과 송출 여부를 제어하게 된다.This cooling process, first through the valve 412 before the coolant is discharged into the FT fixed bed reactor 10 through the coolant spray pipe 41, as shown in Figure 5, through the valve 412 It will control the pressure and delivery.

냉각수가 송출되면, 냉각수분사관(41)의 분사구(411)를 통해 촉매파이프고정공간부(22)로 냉각수를 분사하게 된다.When the coolant is sent out, the coolant is injected into the catalyst pipe fixing space 22 through the injection port 411 of the coolant spray pipe 41.

그러면 인접한 촉매파이프(70)는 냉각수의 증발잠열에 의해 온도가 200 ~ 350℃ 의 범위로 내려가게 된다.Then the adjacent catalyst pipe 70 is lowered in the temperature range of 200 ~ 350 ℃ by the latent heat of evaporation of the cooling water.

여기서 증발된 냉각수는 고온에 의해 스팀화 되어 열풍배출구(13)로 배출된다.The cooling water evaporated here is steamed by the high temperature and discharged to the hot air outlet (13).

이러한 냉각과정은 작은 량의 냉각수를 냉각수분사관(41)에 고압으로 분사시켜 증발 잠열로 촉매파이프(70)의 발열온도를 조절함은 물론 반응기 내부의 열로 인해 증발되는 냉각수는 스팀형태로 배출되어 별도의 에너지원(반응기 내부로 공급 되는 합성가스 예열용)으로 사용이 가능하고, 에너지 소비가 작은 장점이 있다.In this cooling process, a small amount of cooling water is injected into the cooling water injection pipe 41 at high pressure to control the exothermic temperature of the catalyst pipe 70 as the latent heat of evaporation, and the cooling water evaporated by the heat inside the reactor is discharged in the form of steam. It can be used as a separate energy source (for preheating the syngas supplied into the reactor) and has the advantage of low energy consumption.
