Abstract
Description
본 발명은 황화수소 제거용 무기 흡착제에 관한 것으로서, 보다 상세하게는, 상온보다 높은 고온에서뿐만 아니라 상온에서도 황화수소에 대한 흡착성능이 장시간 유지되는 황화수소 제거용 무기 흡착제에 관한 것이다.The present invention relates to an inorganic adsorbent for removing hydrogen sulfide, and more particularly, to an inorganic adsorbent for removing hydrogen sulfide whose adsorption performance against hydrogen sulfide is maintained not only at a high temperature higher than room temperature but also at a room temperature for a long time.
악취는 황화수소, 메르캅탄류, 아민류 기타 자극성 있는 기체상 물질이 사람의 후각을 자극하여 불쾌감과 혐오감을 주는 냄새로, 인체에 미치는 위험성보다는 정신적, 심리적 피해를 끼치는 감각공해로서, 악취의 원인이 되는 물질은 그 종류가 대단히 많을 뿐만 아니라 악취물질간의 복합적인 작용이나 후각의 개인적인 차이 등으로 인하여 느끼는 정도나 피해정도를 일률적으로 나타내기가 어려워 대기오염 중에서도 가장 까다롭고 해결하기 어려운 공해문제 중의 하나로 취급하고 있다.Odor is a sensory pollution that causes psychological and psychological damage rather than a danger to human body due to the smell that hydrogen sulfide, mercaptans, amines and other irritating gaseous substances stimulate the smell of people by giving offensive and disgusting odor. In addition to the large number of substances, they are regarded as one of the most difficult and difficult to solve pollution problems among air pollution because it is difficult to uniformly measure the degree of damage or damage due to the complex action of odorous substances or individual differences in smell .
이러한 악취는 다양한 산업시설과 공정, 그리고 생활주변에서 광범위하게 발생함에 따라 대기환경보전법에서는 문제발생 여지가 큰 대기오염물질 배출시설에 대해서는 배출허용기준을 정하여 엄격하게 관리하고 있으며, 대기오염물질 배출시설 이외의 일정 시설들을 생활악취시설로 규정하여 관리하고 있다. Since these odors are generated in a wide range of industrial facilities, processes, and living environments, the Air Pollutant Conservation Act strictly controls air pollutant emission facilities, Other facilities are designated and managed as living odor facilities.
이러한 악취물질은 단독으로 발생하여 피해를 주는 것이 아니라 악취물질 서로간의 상호작용으로 인하여 복합적으로 작용하여 측정과 탈취에 많은 어려움이 따르고 있다. 탈취기술은 제거하고자 하는 물질의 물리적, 화학적 성질에 따라 그 방법이 다양하며, 최근에는 생물공학기술의 급격한 발전에 따라 미생물에 의한 생물학적 탈취가 개발되고 보급되고 있다. 그러나 탈취기술의 국내 개발수준은 연구차원에서만 진행되어 악취공해문제 해결을 위한 적절한 탈취대책을 제공하지 못하고 있으며, 시범적으로 하수처리장에 설치된 약액세정이나 활성탄 등의 탈취방법이 이용되지만 운용여건상의 한계로 인해 탈취성능이 거의 상실되고 있어 탈취기술의 상용화가 절실한 실정이다. These odorous substances are not caused by themselves and they are harmful, but they are complex due to mutual interaction of odorous substances, which makes it difficult to measure and deodorize them. Deodorization techniques vary depending on the physical and chemical properties of the substance to be removed. Recently, biological deodorization by microorganisms has been developed and popularized due to the rapid development of the biotechnology. However, the domestic development level of deodorization technology is only in the research level, and it does not provide proper deodorization measures to solve the odor pollution problem, and the deodorization method such as chemical solution cleaning or activated carbon installed in the sewage treatment plant is used as a pilot, The deodorization performance is almost lost, and commercialization of the deodorization technology is urgently required.
악취물질을 제거하기 위한 탈취방법 중 흡착법이 가장 많이 이용되는데 흡착제로 사용되는 활성탄은 그 광범한 표면의 물리적 힘이나 기공으로의 내부확산, 모세관 응축 등의 작용에 의하여 많은 물질을 상당히 대량으로 흡착 보전할 수 있다. 또한 활성탄은 소수성의 중성물질에 대하여 특히 효과적인 흡착성을 발휘하기 때문에 탈취용 흡착제로 많이 사용되어 왔지만 중성성분 이외의 산성 성분이나 염기성 성분에 대하여 더욱 효과적인 흡착작용을 일으키는 흡착제의 출현이 요구되고 있다. 따라서 활성탄 표면을 개질하거나 화학약품을 첨착시켜 특정 성분에 대한 선택적 흡착성을 가지는 악취가스 제거용 활성탄이 많이 이용되고 있다. 활성탄에 대한 흡착 친화도가 낮은 가스의 경우에는 화학적 첨착물을 첨가한 첨착활성탄을 사용함으로써 탈취효과도 증대시키고, 탈취조작 운전시간의 연장으로 인한 경제적인 탈취조작이 가능하다.Among the deodorization methods for removing odor materials, the most widely used adsorption method is activated carbon, which is used as an adsorbent, because of the physical force of its wide surface, internal diffusion into pores, capillary condensation, etc., can do. In addition, activated carbon has been widely used as an adsorbent for deodorization because it exhibits particularly effective adsorption to hydrophobic neutral substances, but the appearance of an adsorbent that causes a more effective adsorption action on acidic or basic components other than the neutral component is required. Therefore, activated carbon for removing odor gas, which has selective adsorption on specific components by modifying the activated carbon surface or impregnating chemicals, is widely used. In the case of gas with low adsorption affinity for activated carbon, impregnated activated carbon added with chemical impregnation increases the deodorization effect and economical deodorization operation is possible due to extension of operation time of deodorization operation.
한편, 또 다른 흡착제로 사용되는 산화철은 적당한 탈황률을 얻을 수 있고, 탈황평형도 운전압력에 영향을 주지 않기 때문에 적당하며, 활성성분인 산화철은 환원반응(Fe2O3→Fe3O4→FeO→Fe), 황화반응(Fe3O4, FeO, Fe→FeS), 재생반응(FeS→Fe2O3)의 3가지 반응으로 인해 반복사용 가능하다.On the other hand, iron oxide used as another adsorbent is suitable because it can obtain an appropriate desulfurization rate and does not affect the operation pressure of the desulfurization equilibrium. The iron oxide which is the active ingredient is reduced (Fe 2 O 3 → Fe 3 O 4 → (FeO → Fe), sulfation reaction (Fe 3 O 4 , FeO, Fe → FeS) and regeneration reaction (FeS → Fe 2 O 3 ).
그러나 상술한 바와 같은 종래의 황화수소 흡착제에서는 그 성능의 유지시간이 대략 500~2200 min으로 알려져 있으나, 대략 20~30℃의 상온에서는 성능 유지시간이 현저히 감소하여 대략 500 min 내외를 나타내고 있다. 따라서 종래의 황화수소 흡착제에서는 상온에서 장시간 사용할 수 있는 흡착제로는 부적합한 실정이었다.However, in the conventional hydrogen sulfide adsorbent described above, the performance retention time is known to be about 500 to 2,200 min. However, at a room temperature of about 20 to 30 캜, the performance retention time is remarkably reduced to about 500 min. Therefore, the conventional hydrogen sulfide adsorbent is not suitable as an adsorbent which can be used at room temperature for a long time.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은, 상온보다 높은 고온에서뿐만 아니라 상온에서도 황화수소에 대한 흡착성능이 장시간 유지되는 황화수소 제거용 무기 흡착제를 제공하는 데 있다.It is an object of the present invention to provide an inorganic adsorbent for removing hydrogen sulfide in which adsorption performance against hydrogen sulfide is maintained for a long time not only at a high temperature higher than room temperature but also at a room temperature.
상기한 바와 같은 목적을 달성하기 위한 본 발명의 특징에 따르면, 본 발명은, 황화수소 제거용 무기 흡착제에 관한 것으로, 산화철, 수산화칼슘, 알루미나, 분말형 활성탄, 벤토나이트 및 탄산칼륨을 포함하여 구성된다.According to an aspect of the present invention, there is provided an inorganic adsorbent for removing hydrogen sulfide, which comprises iron oxide, calcium hydroxide, alumina, powdered activated carbon, bentonite, and potassium carbonate.
여기서, 상기 산화철(Fe2CO3)은 20~40중량%, 상기 수산화칼슘(Ca(OH)2)은 15~25중량%, 상기 알루미나는 10~30중량%, 상기 분말형 활성탄은 15~25중량%, 상기 벤토나이트는 3~7중량%이고, 상기 탄산칼륨(K2CO3)은 8~30중량%인 것이 바람직하다.20 to 40 wt% of the iron oxide (Fe 2 CO 3 ), 15 to 25 wt% of the calcium hydroxide (Ca (OH) 2 ), 10 to 30 wt% of the alumina, 15 to 25 wt% of the powdery activated carbon By weight, the bentonite is 3 to 7% by weight, and the potassium carbonate (K 2 CO 3 ) is 8 to 30% by weight.
또한 본 발명에 따른 무기 흡착제는, 상기 산화철(Fe2CO3) 27중량%, 수산화칼슘(Ca(OH)2) 18중량%, 알루미나 13.5중량%, 분말형 활성탄 18중량%, 벤토나이트 4.5중량%, 및 탄산칼륨(K2CO3) 19중량%를 포함하여 구성되는 것이 보다 바람직하다.The inorganic adsorbent according to the present invention may further contain 27 wt% of iron oxide (Fe 2 CO 3 ), 18 wt% of calcium hydroxide (Ca (OH) 2 ), 13.5 wt% of alumina, 18 wt% of powdery activated carbon, And 19 wt% of potassium carbonate (K 2 CO 3 ).
그리고 상기 알루미나는 활성알루미나 또는 수산화알루미나 중 하나이다.And the alumina is one of activated alumina or alumina hydroxide.
또한 상기 탄산칼륨은 분말상으로 가공되어 혼합되는 것이 바람직하다.Further, it is preferable that the above-mentioned potassium carbonate is processed and mixed in a powder form.
본 발명에 따른 황화수소 제거용 무기 흡착제에 따르면, 상온보다 높은 고온에서뿐만 아니라 상온에서도 황화수소에 대한 흡착성능이 장시간 유지되므로, 고온환경에서 황화수소가 발생되는 산업설비뿐만 아니라 상온환경에서 황화수소가 발생하는 가정 등에서도 폭넓고 유용하게 활용가능하다는 효과가 있다. According to the inorganic adsorbent for removing hydrogen sulfide according to the present invention, since the adsorption performance against hydrogen sulfide is maintained for a long time not only at a high temperature higher than room temperature but also at a room temperature, not only industrial equipment in which hydrogen sulfide is generated in a high temperature environment, Is also widely available and useful.

이하, 첨부된 도면을 참조하여 본 발명에 따른 황화수소 제거용 무기 흡착제의 구성을 자세히 설명한다.Hereinafter, the structure of the inorganic adsorbent for removing hydrogen sulfide according to the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 황화수소 제거용 무기 흡착제는 산화철(Fe2CO3) 20~40중량%, 수산화칼슘(Ca(OH)2) 15~25중량%, 알루미나 10~30중량%, 분말형 활성탄 15~25중량%, 벤토나이트 3~7중량%, 및 탄산칼륨(K2CO3) 8~30중량%를 포함하여 구성된다. The inorganic adsorbent for removing hydrogen sulfide according to the present invention comprises 20 to 40% by weight of iron oxide (Fe 2 CO 3 ), 15 to 25% by weight of calcium hydroxide (Ca (OH) 2 ), 10 to 30% by weight of alumina, % By weight of bentonite, 3 to 7% by weight of bentonite, and 8 to 30% by weight of potassium carbonate (K 2 CO 3 ).
상기 구성요소 중에서 산화철과 활성탄은, 종래기술에서도 언급한 바와 같이, 황화수소의 흡착 성능이 우수한 것으로 알려진 재료로서, 본 발명에서도 이들 재료를 활용하되, 보다 향상된 흡착성능을 발휘 및 유지하기 위해서 다양한 활성물질을 연구하였고, 그 결과로서 상기와 같은 구성요소들의 배합을 얻을 수 있게 되었다. Among the above-mentioned components, iron oxide and activated carbon are materials known to have excellent adsorbing ability of hydrogen sulfide as mentioned in the background art. In order to exhibit and maintain a more improved adsorption performance, various active substances And as a result, a combination of the above-described components can be obtained.
그리고 수산화칼슘과 알루미나에서 황화수소의 제거 효능은 특별히 발견되지 않지만, 흡착제의 강도 향상을 위하여 수산화칼슘이 첨가되고, 또한 알루미나는 활성알루미나 및 수산화알루미나 중에서 사용 가능하지만, 수산화칼슘과 더불어 강도향상에 기여할 뿐만 아니라 원가 절감이 가능한 수산화알루미나를 사용하는 것이 보다 바람직하다.Although the effect of removing hydrogen sulfide from calcium hydroxide and alumina is not particularly found, calcium hydroxide is added to improve the strength of the adsorbent, and alumina can be used in activated alumina and alumina hydroxide. However, in addition to calcium hydroxide, It is more preferable to use alumina hydroxide which can be used.
한편, 탄산칼륨(K2CO3)은 황화수소 제거 효능을 향상시킬 수 있는 활성물질로 확인된 재료로서, 전체 중량비에서 8~30중량% 범위 내에서 우수한 성능을 발휘하는 것으로 나타났다.On the other hand, potassium carbonate (K 2 CO 3 ) is a material identified as an active material capable of improving the hydrogen sulfide removal efficiency, and exhibits excellent performance within a range of 8 to 30 wt% based on the total weight ratio.
이와 같이 황화수소 제거 성능 및 유지 성능을 발휘하는 활성물질 및 배합비율을 검증하기 위하여 평가 레진(resin)과 상기 평가 레진에 '요오드화 칼륨(potassium iodide, KI)', '수산화칼륨(potassium hydroxide, KOH)', 또는 '탄산칼륨(K2CO3)'을 첨가하여 실험을 실시하였다, In order to verify the active material and the mixing ratio exhibiting the hydrogen sulfide removal performance and maintenance performance, 'potassium iodide (KI)', 'potassium hydroxide (KOH)', ', Or' potassium carbonate (K 2 CO 3 ) ',
이때 평가 레진은, 산화철 30g, 분말 활성탄 10g, 활성 알루미나 15g, 수산화칼슘 30g 및 벤토나이트 5g을 혼합하여 제조하였고, 상기 평가 레진에 KOH 5g을 첨가한 형태, KI 5g을 첨가한 형태, K2CO3 5g을 첨가한 형태를 제조하였다. The evaluation resin was prepared by mixing 30 g of iron oxide, 10 g of powdered activated carbon, 15 g of activated alumina, 30 g of calcium hydroxide and 5 g of bentonite. 5 g of KOH was added to the evaluation resin, 5 g of KI was added, 5 g of K 2 CO 3 To prepare a form.
그리고 그에 대한 결과가 도 1에 도시된 바와 같고, 황화수소를 90% 제거하는 시점까지의 효능유지 시간값을 나타내면 다음의 [표 1]과 같다.The results are shown in FIG. 1, and the efficacy holding time until 90% removal of hydrogen sulfide is shown in Table 1 below.
Resin Resin Series
도 1과 [표 1]을 토대로 정리하면, 활성물질별 평가 결과는 K2CO3를 첨가한 형태가 가장 우수하였고, KOH를 첨가한 형태보다는 대략 60% 이상, KI를 첨가한 형태보다는 대략 160% 이상 향상된 성능을 나타내었다.Based on the results of Table 1 and Table 1, the evaluation results of the active materials showed the best results with K 2 CO 3 added, about 60% higher than that with KOH, and about 160 with KI % Performance improvement.
다음으로는, 이와 같이 우수한 황화수소 제거 성능을 보이는 활성물질로 K2CO3를 활용할 때, 다른 물질과의 최적의 배합비율을 결정하기 위하여 산화철, 수산화칼슘, 알루미나, 분말 활성탄 및 벤토나이트의 배합비율은 고정한 상태에서 K2CO3의 함량만 변경하면서 실시예 1 내지 5를 제조하였고, 그 구체적인 배합비율은 [표 2]와 같다. 그리고 대비를 위하여 활성탄 97중량%와 KI 3중량%를 혼합한 흡착제를 비교예로 제조하였다.Next, when K 2 CO 3 is used as an active material exhibiting such excellent hydrogen sulfide removal performance, the compounding ratio of iron oxide, calcium hydroxide, alumina, powdered activated carbon and bentonite is fixed to determine the optimal blending ratio with other materials Examples 1 to 5 were prepared by changing only the content of K 2 CO 3 in the form of [Table 2]. For comparison, an adsorbent prepared by mixing 97 wt% of activated carbon and 3 wt% of KI was prepared as a comparative example.
K 2 CO 3
[표 2]에 나타난 바와 같은 실시예 1 내지 5와 비교예에 대해 황화수소의 제거 효율을 대략 27℃의 온도에서 실험하였고, 그 결과는 도 2에 도시된 바와 같다. As shown in Table 2, the removal efficiency of hydrogen sulfide was tested at temperatures of about 27 캜 for Examples 1 to 5 and Comparative Example, and the results are shown in Fig.
도시된 바와 같이, 비교예에서 황화수소 90% 제거 효능 유지시간은 대략 950min이고, 실시예 1은 700min, 실시예 2는 1750min, 실시예 3은 2770min, 실시예 4는 1950min으로서 실시예 1을 제외하고는 실시예 2 내지 4가 비교예에 비해 대략 2배 정도의 효능 향상을 나타내었고, 특히 실시예 3은 대략 3배 정도의 효능 향상을 나타내었다. 따라서 K2CO3는 [표 2]와 같은 배합비율일 때 대략 20중량% 전후에서 가장 좋은 활성을 나타냄을 확인할 수 있다. As shown in the figure, in the comparative example, the holding time of the 90% hydrogen sulfide removal efficacy is about 950 min, except that Example 1 is 700 min, Example 2 is 1750 min, Example 3 is 2770 min and Example 4 is 1950 min. Of Examples 2 to 4 exhibited an improvement in efficacy of about two times as compared with those of Comparative Example, and in Example 3, the efficacy was improved by about three times. Therefore, it can be confirmed that K 2 CO 3 shows the best activity at around 20 wt% when the compounding ratio is as shown in [Table 2].
그리고 실시예 1 내지 4에서는 K2CO3를 증류수 30㎖에 용해한 후에 첨가한 것이고, 실시예 5는 분말상으로 첨가한 것으로, 실시예 1과 대비하여 분말상의 효과를 검증하기 위하여 제조된 것이다. 이에 대한 결과로 도 2를 보면, 실시예 1은 비교예에 비해 효능이 떨어지지만, 실시예 5는 대략 1400min으로서 비교예에 비해 향상된 효능을 나타냄을 알 수 있다. 따라서 K2CO3를 첨가할 경우, 용액상 보다는 분말상으로 첨가하는 것이 효능 향상에 기여함을 알 수 있다. 이는 K2CO3를 분말상으로 사용할 경우에 화학반응에 의해 공기중으로 유출되는 탄산의 발생을 억제하여 황화수소의 제거에 기여하는 K2CO3를 보다 온전히 보전할 수 있기 때문으로 판단된다.In Examples 1 to 4, K 2 CO 3 was added after dissolving in 30 ml of distilled water. Example 5 was prepared in order to verify the effect of powder in comparison with Example 1, which was added in powder form. As a result, FIG. 2 shows that Example 1 is less effective than the Comparative Example, but Example 5 shows an improved effect as compared with Comparative Example at about 1400 min. Therefore, when K 2 CO 3 is added, it can be seen that the addition of the powder phase rather than the solution phase contributes to the improvement of the efficacy. This is because the use of K 2 CO 3 in the form of a powder suppresses the generation of carbon dioxide which is released into the air by chemical reaction, and thus K 2 CO 3 , which contributes to the removal of hydrogen sulfide, can be more fully preserved.
이러한 결과를 종합하여 볼 때, 산화철(Fe2CO3) 20~40중량%, 수산화칼슘(Ca(OH)2) 15~25중량%, 알루미나 10~30중량%, 분말형 활성탄 15~25중량%, 벤토나이트 3~7중량%, 및 탄산칼륨(K2CO3) 8~30중량%를 포함하여 구성되되, 상기 탄산칼륨은 분말형으로 가공되어 혼합되는 것이 바람직하다. 또한 황화수소 제거 효능 유지시간을 최상으로 하기 위해서는, 상기 산화철(Fe2CO3) 27중량%, 수산화칼슘(Ca(OH)2) 18중량%, 알루미나 13.5중량%, 분말형 활성탄 18중량%, 벤토나이트 4.5중량%, 및 탄산칼륨(K2CO3) 19중량%를 포함하여 구성할 수 있고, 이 경우 황화수소 제거 효능 유지시간을 대략 2700min 이상으로 예상할 수 있다.These results indicate that 15 to 25 wt% of iron oxide (Fe 2 CO 3 ), 20 to 40 wt% of calcium hydroxide (Ca (OH) 2 ), 10 to 30 wt% of alumina, 15 to 25 wt% 3 to 7% by weight of bentonite, and 8 to 30% by weight of potassium carbonate (K 2 CO 3 ), wherein the potassium carbonate is processed into powder and mixed. In order to maximize the holding time of the hydrogen sulfide removal effect, it is necessary to use the above-mentioned iron oxide (Fe 2 CO 3 ) 27 wt%, calcium hydroxide (Ca (OH) 2 ) 18 wt%, alumina 13.5 wt%, powdery activated carbon 18 wt% By weight, and 19% by weight of potassium carbonate (K 2 CO 3 ). In this case, the hydrogen sulfide removal efficiency holding time can be estimated to be about 2700 min or more.
한편, 본 발명에 따른 황화수소 제거용 무기 흡착제의 제조방법은, 혼합공정, 반죽공정, 가공공정 및 건조공정으로 이루어진다.Meanwhile, the method for producing an inorganic adsorbent for removing hydrogen sulfide according to the present invention comprises a mixing step, a kneading step, a processing step and a drying step.
상기 혼합공정에서는, 상술한 바와 같이, 산화철(Fe2CO3) 20~40중량%, 수산화칼슘(Ca(OH)2) 15~25중량%, 알루미나 10~30중량%, 분말형 활성탄 15~25중량%, 벤토나이트 3~7중량%, 및 탄산칼륨(K2CO3) 8~30중량%를 준비하여 혼합한다.In the mixing step, as described above, 20 to 40 wt% of iron oxide (Fe 2 CO 3 ), 15 to 25 wt% of calcium hydroxide (Ca (OH) 2 ), 10 to 30 wt% of alumina, 3 to 7% by weight of bentonite, and 8 to 30% by weight of potassium carbonate (K 2 CO 3 ) are prepared and mixed.
그리고 반죽공정에서는, 상기에서 혼합된 혼합물 100중량부에 대해 35~45중량부의 증류수를 혼합하여 반죽한다. In the kneading process, 35 to 45 parts by weight of distilled water is mixed with 100 parts by weight of the mixture to be kneaded.
가공공정에서는, 이렇게 반죽된 혼합물은 파쇄 타입 또는 펠렛 타입과 같이, 용도에 따른 성형타입에 맞추어 가공한다. 이때 성형타입에 따른 황화수소의 흡착량 변화는 없는 것으로 확인되었다.In the processing step, the thus kneaded mixture is processed in accordance with the molding type according to the application, such as a crushing type or a pellet type. At this time, it was confirmed that there was no change in adsorption amount of hydrogen sulfide according to the molding type.
마지막으로 건조공정에서는, 가공된 혼합물을 오븐에서 대략 70℃로 가열하여 수분함량이 5%가 되도록 건조한다.Finally, in the drying process, the processed mixture is heated in an oven to approximately 70 DEG C and dried to a moisture content of 5%.
