산업화가 시작된 19세기 초반부터 에너지 산업에서 사용되는 석탄, 석유, LNG 등의 화석연료의 사용 증가로 인하여 대기 중에 CO2, CH4, H2S, COS 등의 산성 가스 농도가 급격하게 증가하였다. 이러한 산성 가스, 특히 이산화탄소는 지구를 온난화시킨다는 것이 밝혀지면서, 세계적으로 배출 및 처리에 대한 규제가 엄격해지고 있다. 1992년 6월 브라질 리우에서 열린 환경과 개발에 관한 UN 회의를 통하여 지구온난화에 대한 국제적 관심을 불러 일으켰고, 미국과 일본을 포함한 선진국들은 지구온실가스 배출량을 1990년 대비 5.2% 감축하기로 합의하는 등 산성가스 저감방안에 대한 국제적 합의가 이루어지고 있다.From the early 19th century, when industrialization started, the concentration of acidic gases such as CO2, CH4, H2S, and COS increased rapidly in the atmosphere due to the increased use of fossil fuels such as coal, petroleum, and LNG. As these acid gases, especially carbon dioxide, have been found to warm the earth, regulations on emissions and disposal are becoming more stringent worldwide. In June 1992, the United Nations Conference on Environment and Development in Rio, Brazil, raised international attention to global warming, and developed countries including the United States and Japan agreed to reduce global greenhouse gas emissions by 5.2% compared to 1990.

이하에서는 본 발명의 실시예에 따른 산성 가스 흡수 분리 시스템 및 방법을 설명하도록 한다.Hereinafter will be described an acid gas absorption separation system and method according to an embodiment of the present invention.

도 1은 본 발명의 실시예에 따른 산성 가스 흡수 분리 시스템을 도시한 구성도이다. 도 1을 참조하여, 본 발명의 실시예에 따른 산성 가스 흡수 분리 시스템 및 방법을 함께 설명하도록 한다.1 is a block diagram showing an acid gas absorption separation system according to an embodiment of the present invention. Referring to Figure 1, it will be described together with the acid gas absorption separation system and method according to an embodiment of the present invention.

도 1을 참조하면, 본 발명의 실시예에 따른 산성 가스 흡수 분리 시스템(100)은 보일러(110), 리보일러(120), 흡수탑(130), 탈거탑(140), 콘덴싱 물탱크(150), 리플럭스 드럼(160)을 포함하여 구성될 수 있다.Referring to Figure 1, the acid gas absorption separation system 100 according to an embodiment of the present invention is a boiler 110, reboiler 120, absorption tower 130, stripping tower 140, condensing water tank 150 ), The reflux drum 160 may be configured.

본 발명의 실시예에 따른 산성 가스 흡수 분리 시스템 및 방법에서는 먼저, ①의 공급 라인을 따라, 상기 보일러(110)에서 상기 리보일러(120)에 증기를 공급한다. 즉, 상기 보일러(110)에서 발생한 증기가 직접 상기 리보일러(120)에 공급된다. 따라서, 증기의 공급 경로에 터빈이 존재하지 않기 때문에, 증기의 단위 열량을 보다 많이 확보할 수 있다.In the acid gas absorption separation system and method according to an embodiment of the present invention, first, steam is supplied from the boiler 110 to the reboiler 120 along a supply line of ①. That is, steam generated in the boiler 110 is directly supplied to the reboiler 120. Therefore, since a turbine does not exist in the steam supply path, more unit heat amount of steam can be ensured.

또한, 별도로 도시하지는 않았지만, 상기 보일러(110)에서 갓 나온 증기는 과열도가 높기 때문에, 상기 리보일러(120)에 증기를 공급할 때 물을 뿌려줌으로써 과열도를 낮출 수 있다. 따라서, 상기 리보일러(120)에 연결된 상기 탈거탑(140)의 재생용 열원으로 활용시 열교환기의 재질 선정 등에 있어서 탄력적인 대응이 가능하다.In addition, although not separately illustrated, since fresh steam from the boiler 110 has a high superheat, the superheat may be lowered by spraying water when steam is supplied to the reboiler 120. Therefore, when used as a heat source for regeneration of the stripping column 140 connected to the reboiler 120, it is possible to flexibly respond to the material selection of the heat exchanger.

다음으로, 상기 리보일러(120)로부터 상기 증기가 린 아민 펌프(lean amine pump, 121)에 의해 ②의 공급 라인을 따라서 린/리치 아민 교환기(122, lean/rich amine exchanger)에 공급된다. 이 때, 상기 린/리치 아민 교환기(122)는 상기 ②의 공급 라인을 따라 증기(린 아민, lean amine)을 공급받고, 이와 교차하는 ⑤의 공급 라인을 따라 콘덴서(161)로부터 흡수제(리치 아민, rich amine)를 각각 공급받는다. 그리고 상기 린/리치 아민 교환기(122)는 상기 증기의 열로써, 상기 흡수제의 온도를 높인다.Next, the steam from the reboiler 120 is supplied to a lean / rich amine exchanger 122 along a supply line of ② by a lean amine pump 121. At this time, the lean / rich amine exchanger 122 is supplied with steam (lean amine) along the supply line of ②, and the absorbent (rich amine) from the condenser 161 along the supply line of ⑤ to cross the and rich amine). The lean / rich amine exchanger 122 increases the temperature of the absorbent by heat of the steam.

따라서, 저온의 흡수제를 상기 흡수탑(140)에 공급하기 전에 미리 상기 증기를 통해 흡수제의 온도를 높이는 것이 가능하기 때문에, 상기 흡수제를 가열하는데 필요한 열량 만큼의 에너지를 줄일 수 있다.Therefore, since it is possible to raise the temperature of the absorbent through the vapor in advance before supplying the low temperature absorbent to the absorption tower 140, energy by the amount of heat required to heat the absorbent can be reduced.

그리고, 상기 증기는 린 아민 쿨러(lean amine cooler, 123)를 통해 산성 가스 흡수에 적합한 저온으로 냉각되고, ③의 공급 라인을 따라 상기 흡수탑(130)에 공급된다. 상기 흡수탑(130)은 인렛관(131)로부터 산성 가스를 주입받고, 흡수제를 통해 이를 흡수한다. 이 때의 산성 가스는 일 예로, 이산화탄소(CO2), 황화수소(H2S), 이산화황(SO2), 이산화질소(NO2) 또는 황산화탄소(COS)등 일 수 있다.The steam is cooled to a low temperature suitable for acid gas absorption through a lean amine cooler 123, and is supplied to the absorption tower 130 along a supply line 3. The absorption tower 130 receives the acid gas from the inlet tube 131 and absorbs it through the absorbent. In this case, the acid gas may be, for example, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), sulfur dioxide (SO 2), nitrogen dioxide (NO 2), or carbon sulfate (COS).

이후, ④의 공급 라인을 따라, 리치 아민 펌프(132)에 의해 저온의 상기 흡수제가 콘덴서(161)에 공급된다. 또한, 상기 콘덴서(161)는 이와 교차하는 ⑦의 공급 라인을 통해, 상기 탈거탑(140)로부터 고온의 처리 가스를 공급받는다.Then, along the supply line ④, the low temperature absorbent is supplied to the condenser 161 by the rich amine pump 132. In addition, the condenser 161 receives a high temperature processing gas from the stripping column 140 through a supply line ⑦ that crosses the condenser 161.

그리고 상기 콘덴서(161)는 상기 저온의 흡수제와 고온의 처리 가스의 상호간에 열 교환이 일어나도록 한다. 따라서, 상기 저온의 흡수제는 상기 고온의 처리 가스의 열을 흡수하고, 그 결과 공정 자체에서 발생한 열을 흡수할 수 있다. 또한, 이와 동시에 상기 고온의 처리 가스는 상기 저온의 흡수제에 열을 방출함에 따라 냉각될 수 있다.The condenser 161 causes heat exchange between the low temperature absorbent and the high temperature processing gas. Accordingly, the low temperature absorbent absorbs heat of the high temperature process gas, and as a result, may absorb heat generated in the process itself. At the same time, the high temperature process gas may be cooled by dissipating heat to the low temperature absorbent.

이후, 상기 콘덴서(161)를 통과한 흡수제는 ⑤의 공급 라인을 통해, 상기 린/리치 아민 교환기(122)에 공급된다. 따라서, 상술한 바와 같이, 상기 리보일러(120)로부터 상기 흡수탑(130)으로 공급되는 증기는 상기 콘덴서(161)로부터 공급된 흡수제에 의해 냉각되는 반면, 상기 콘덴서(161)로부터 공급된 흡수제는 증기에 의해 가열된다. 따라서, 상기 콘덴서(161)로부터 공급된 흡수제는 가열된 상태로 ⑥의 공급 라인을 통해, 상기 탈거탑(140)으로 공급되고, 이후 탈거 공정이 진행된다.Thereafter, the absorbent passing through the condenser 161 is supplied to the lean / rich amine exchanger 122 through a supply line ⑤. Thus, as described above, the steam supplied from the reboiler 120 to the absorption tower 130 is cooled by the absorbent supplied from the condenser 161, while the absorbent supplied from the condenser 161 Heated by steam. Therefore, the absorbent supplied from the condenser 161 is supplied to the stripping column 140 through the supply line of ⑥ in a heated state, and then the stripping process is performed.

그리고 상술한 바와 같이, ⑦의 공급 라인을 통해, 상기 탈거탑(140)의 처리 가스는 상기 콘덴서(161)에 공급되고, 상기 콘덴서(161)에 공급된 저온의 흡수제에 의해 냉각된 상태로 상기 리플럭스 드럼(160)에 공급된다.As described above, the processing gas of the stripping column 140 is supplied to the condenser 161 through the supply line ⑦ and is cooled in the state of being cooled by the low temperature absorbent supplied to the condenser 161. Supplied to the reflux drum 160.

또한, 상기 콘덴서(161)를 통과하여 냉각된 고온의 처리 가스는 리플럭스 드럼(160)에 공급되어 응축된다. 또한, 응축된 처리가스는 상기 탈거탑(140)의 상부로 환류되지 않고, ⑧의 공급 라인을 따라 상기 리보일러(120)에 직접 공급된다. 따라서, 상기 탈거탑(140)의 탈거시 독립적인 운전이 가능하게 되어, 탈거 능력을 향상시킬 수 있다.In addition, the hot processing gas cooled by passing through the condenser 161 is supplied to the reflux drum 160 to condense. In addition, the condensed process gas is not directly refluxed to the upper portion of the stripping column 140, but is directly supplied to the reboiler 120 along the supply line of ⑧. Therefore, independent operation is possible when the stripping tower 140 is removed, thereby improving the stripping capability.

한편, 상기 흡수탑(130)으로부터 나온 처리 배가스는 콘덴서(151)를 통해 콘덴싱 물탱크(150)로 공급된다. 또한, 상기 처리 배가스의 습분은 상기 콘덴싱 물탱크(150)에 수집되고, 수집된 습분은 ⑨의 공급 라인을 따라 발전용 용수로 재사용된다. 따라서, 자원 활용 효과를 향상시킬 수 있다.On the other hand, the treatment off-gas from the absorption tower 130 is supplied to the condensing water tank 150 through the condenser 151. In addition, the moisture of the treated exhaust gas is collected in the condensing water tank 150, and the collected moisture is reused as water for power generation along the supply line of ⑨. Therefore, the resource utilization effect can be improved.
