이하 본 발명 철강재료 절단가스용 첨가제 조성물 제조방법을 설명한다.Hereinafter, a method for manufacturing an additive composition for cutting gas for steel materials of the present invention will be described.
본 발명은,The present invention is
메탄올 40 내지 50 중량부에 인산트리뷰틸 30 내지 40 중량부를 부가하여 인산트리뷰틸을 용해하는 제1단계;A first step of dissolving tributyl phosphate by adding 30 to 40 parts by weight of tributyl phosphate to 40 to 50 parts by weight of methanol;
상기 제1단계에서 제조한 혼합액에 에틸아세테이트 15 내지 25 중량부를 부가하여 혼합하는 제2단계;A second step of mixing by adding 15 to 25 parts by weight of ethyl acetate to the mixture prepared in the first step;
상기 제2단계에서 제조한 혼합액에 중탄산나트륨을 부가하여 혼합하는 제3단계;를 포함한다.and a third step of mixing by adding sodium bicarbonate to the mixed solution prepared in the second step.
본 발명에서 상기 제1단계는 메탄올과 인산트리뷰틸을 교반탱크에 투입한 후 1시간 내지 1시간 30분 교반하여 용해작업을 진행한다.In the first step of the present invention, methanol and tributyl phosphate are added to a stirred tank and then stirred for 1 hour to 1 hour and 30 minutes to proceed with dissolution.
이때 붕사 50 내지 80kg을 부가하여 붕사가 이온화하면서 완전히 용해된다.At this time, 50 to 80 kg of borax is added to completely dissolve the borax while ionizing.
본 발명에서 상기 제2단계는 상기 제1단계에서 제조된 혼합액에 에틸아세테이트 15 내지 25 중량부를 부가하여 혼합하는데, 이때 부가된 에틸아세테이트은 상기 제1단계에서 이온화된 붕사 이온이 다시 석출되는 것을 방지하는 작용을 한다.In the second step in the present invention, 15 to 25 parts by weight of ethyl acetate is added to the mixed solution prepared in the first step and mixed, and in this case, the added ethyl acetate prevents the borax ions ionized in the first step from precipitating again it works
본 발명에서 상기 제3단계는 상기 제2단계에서 제조한 혼합액에 중탄산나트륨을 부가하여 최종적인 첨가제를 제조한다. In the third step of the present invention, sodium bicarbonate is added to the mixed solution prepared in the second step to prepare a final additive.
이때 상기 중탄산나트륨은 철강재료 절단가스용 첨가제 조성물 전체 중량의 3 내지 5 중량부를 부가함이 바람직하다.At this time, it is preferable to add 3 to 5 parts by weight of the sodium bicarbonate based on the total weight of the additive composition for cutting gas for steel materials.
본 발명의 바람직한 실시형태에 따른 철강재료 절단가스용 첨가제 조성물은, 여기에 한정되는 것은 아니지만, LPG, LNG, COG연료의 연소속도 및 연소온도를 증가시켜 연소 효율를 향상시킬 수 있다.The additive composition for cutting gas for steel materials according to a preferred embodiment of the present invention, but is not limited thereto, can improve combustion efficiency by increasing the combustion rate and combustion temperature of LPG, LNG, and COG fuel.
특히 본 발명은 철강재료 절단가스용 첨가제 조성물로서 완전연소를 촉진하도록 활성화 에너지를 낮추고 산소 공급을 극대화시키게 된다.In particular, the present invention is an additive composition for cutting gas for steel materials, which lowers the activation energy to promote complete combustion and maximizes oxygen supply.
여기서 절단가스용 첨가제로 들어간 대부분의 물질이 메탈에 비해 발열량이 커서 연소속도가 빠르기 때문에 짧은 시간 내에 적은 메탄가스 사용으로도 동일한 효과를 얻는다.Here, since most of the materials used as additives for cutting gas have a high calorific value compared to metal and have a faster combustion rate, the same effect can be obtained even with a small amount of methane gas in a short time.
이때 인산트리뷰틸 및 에틸아세테이트는 금속을 용해시키는 기능을 지닌 용매로서 철강재료의 절단이 깨끗해진다.At this time, tributyl phosphate and ethyl acetate are solvents with the function of dissolving metals, and the cutting of steel materials becomes clean.
예를 들어, 가스연료가 빨리 연소되도록 하기 위해서는 산소와 빨리 결합할 수 있도록 반응속도를 높여야 하는데, 이러한 연료의 연소반응은 일반적으로 아래와 같이 표현될 수 있다.For example, in order to rapidly combust gas fuel, the reaction rate must be increased so that it can be rapidly combined with oxygen, and the combustion reaction of such fuel can be generally expressed as follows.
메탄올 연소반응 (45%)Methanol combustion reaction (45%)
CH3OH + 1.5 O2 → CO2 + 2H2O +6,825[kcal/Nm3] CH 3 OH + 1.5 O 2 → CO 2 + 2H 2 O +6,825[kcal/Nm 3 ]
인산트리뷰틸 연소반응 (35%)Tributyl phosphate combustion reaction (35%)
2C12H27O4P + 33½O2 → 24CO2 + 27H2O + P2O4 +81,786[kcal/Nm3] 2C 12 H 27 O 4 P + 33½O 2 → 24CO 2 + 27H 2 O + P 2 O 4 +81,786[kcal/Nm 3 ]
에틸 아세테이트 연소반응 (20%)Ethyl acetate combustion reaction (20%)
C4H3O2 + 6O2 → 4CO2 + 4H2O +22,044[kcal/Nm3] C 4 H 3 O 2 + 6O 2 → 4CO 2 + 4H 2 O +22,044[kcal/Nm 3 ]
메탄 연소반응methane combustion
CH4 + 2O2 → CO2 + 2H2O +8,532[kcal/Nm3] CH 4 + 2O 2 → CO 2 + 2H 2 O +8,532[kcal/Nm 3 ]
따라서 본 발명에서는 첨가제 조성물에 관한 것으로 특정한 공정에 의해 제조된 첨가제 조성물에 기타 구성성분을 순차적으로 부가하여 제조하는 제조방법을 제공하는 것이다.Accordingly, the present invention relates to an additive composition, and to provide a manufacturing method for manufacturing by sequentially adding other components to an additive composition prepared by a specific process.
본 발명의 다른 실시형태에 따르면, 인산트리뷰틸은 메탄에 비해 발열량이 약 10배 높기 때문에 메탄 양을 줄이는데 효과적이며, 이 물질은 금속을 용해하여 추출하는 기능을 지닌 용매로서 가열 커팅으로 금속 표면이 깨끗해진다.According to another embodiment of the present invention, tributyl phosphate has a calorific value that is about 10 times higher than that of methane, so it is effective in reducing the amount of methane, and this material is a solvent having a function of dissolving and extracting the metal. it becomes clean
에틸아세테이트는 메탄에 비해 발열량이 2.5배 크기 때문에 메탄 양을 줄이는데 효과적이다.Ethyl acetate is effective in reducing the amount of methane because its calorific value is 2.5 times greater than that of methane.
메탄올은 메탄에 비해 발열량은 약간 낮지만, 다양한 물질을 혼합하는 용매로서 메탄가스, 에틸아세테이트, 인산트리뷰틸 물질을 균일하게 혼합하여 균일한 발열량을 내는데 역할을 한다.Methanol has a slightly lower calorific value compared to methane, but as a solvent for mixing various substances, it plays a role in uniformly mixing methane gas, ethyl acetate, and tributyl phosphate materials to produce a uniform calorific value.
이와 같이, 본 발명에 따라 제조된 첨가제는 LNG등의 연료의 연소 시 발생되는 오염물질의 원천적인 저감과 Kerf size 및 Burr의 감소시키고 완전 연소를 통해 발열량을 극대화시킬 수 있게 한다.As described above, the additive manufactured according to the present invention enables the fundamental reduction of pollutants generated during combustion of fuels such as LNG, the reduction of kerf size and burr, and maximization of calorific value through complete combustion.
이처럼 상기와 같이 본 발명의 실시한 예에 대하여 상세히 설명하였으나, 본 발명의 권리범위는 이에 한정되지 않으며, 본 발명의 실시한 예와 실질적으로 균등의 범위에 있는 것까지 본 발명의 권리범위가 포함되는 것은 당연하다.As described above, the embodiment of the present invention has been described in detail, but the scope of the present invention is not limited thereto, and the scope of the present invention is included to the extent that it is substantially equivalent to the embodiment of the present invention. Of course.
