Description
본 발명은 코크스가스중에 다량 함유되어 있는 나프탈렌이 가스배관에 침적되어 가스배관을 폐쇄시키는 것을 예방할 수 있도록 한 코크스 가스중의 나프탈렌 제거장치에 관한 것이다.The present invention relates to an apparatus for removing naphthalene in coke gas to prevent naphthalene, which is contained in a large amount of coke gas, from being deposited in the gas pipe to close the gas pipe.
일반적으로 코크스가스중에는 나프탈렌이 다량 함유되어 있어 이를 제거하지 않으면 가스배관에 침적되어 폐쇄시키는 역할을 하기 때문에 반드시 일정수준 이하로 제거하여야 한다.In general, coke gas contains a large amount of naphthalene, so if it is not removed, it should be removed to a certain level or less because it acts to close the gas pipe.
나프탈렌은 응축할 때 각종 설비와 배관의 폐쇄를 가져오기 때문에 나프탈렌의 제거는 코크스가스의 정제과정중 중요한 일이다.Removal of naphthalene is an important part of the coke gas refining process because naphthalene leads to the closure of equipment and piping when condensing.
종래에는 도 1에서 도시된 바와같이 코크스가스 냉각기(10)에서 냉각수에 냉각되어 응고된 나프탈렌을 타르(13)에 흡수시켜 제거되도록 하고, 여기에서 일부 넘쳐 나오는 타르(13)를 침전조(11)에서 분리하며, 새로운 타르(13)를 보충하는 방법을 사용하였다.Conventionally, as shown in FIG. 1, the naphthalene cooled by cooling water in the coke gas cooler 10 is absorbed and removed by the tar 13, and some overflowing tar 13 from the settling tank 11 is removed. The method of separating and replenishing the new tar 13 was used.
상기 방법의 특징은 단지 냉각되어 응고된 나프탈렌만을 제거하기 때문에 가스 온도를 너무 많이 낮추어 나프탈렌의 응고량이 많게 되면 응고된 나프탈렌의 폐쇄현상 때문에 가스의 온도를 낮추는데 한계가 있다.The feature of this method is that only the cooled and solidified naphthalene is removed, so if the gas temperature is lowered too much and the amount of naphthalene becomes too large, there is a limit to lowering the temperature of the gas due to the closing of the solidified naphthalene.
이에 따라 냉각기(10) 온도가 높게 관리되어 냉각을 위해 분사된 수분의 비말동반 현상으로 많은 양의 수분이 가스에 첨가되며, 이는 다른 가스 정제 설비의 효율을 저하시키는 요인이 되었다.Accordingly, the temperature of the cooler 10 is controlled to be high, so that a large amount of water is added to the gas by the entrainment of the water sprayed for cooling, which causes a decrease in the efficiency of other gas purification equipment.
또한 낮은 나프탈렌 제거율로부터 초래되는 문제인 나프탈렌 침적에 의한 여러가지 폐쇄 문제를 방지하기 위하여 가스의 온도를 높이게 되는데, 이때에는 가스중 다른 불순물을 제거하는데 여러 가지 문제점을 동반하게 된다.In addition, the temperature of the gas is increased in order to prevent various closure problems due to naphthalene deposition, which is a problem resulting from low naphthalene removal rate, which is accompanied with various problems in removing other impurities in the gas.
코크스가스(15)로부터 나프탈렌을 제거하는 또다른 방법은 기름성분에 흡수시켜 제거하는 것인데, 이 흡수유는 재생하여 사용하기도 하고 재생하지 않기도 한다. 다른 공정들은 가스를 냉각시켜 나프탈렌을 제거하거나 고체물질에 흡착시켜 제거하기도 하는 공정들이 있지만 상업적으로 널리 쓰이고 있지 않다.Another method of removing naphthalene from the coke gas 15 is to remove it by absorbing it in an oil component, which may or may not be recycled. Other processes, such as cooling the gas to remove naphthalene or adsorbing on solids, are not commercially available.
흡수유의 종류로는 석유계 흡수유와, 석탄계 흡수유를 쓰고 있다. 흡수탑의 형태는 충전탑의 형태가 주고 쓰이며, 흡수유와 가스는 서로 반대 방향으로 흐르게 되다.Types of absorbent oil include petroleum absorbent oil and coal-based absorbent oil. Absorption towers are used in the form of packed towers, and oil and gas flow in opposite directions.
이 경우 흡수탑은 두 단계로 나뉘어 운전되며, 하단부에서는 대부분의 흡수유를 재순환시키면서 흡수유 유량이 매우 높기 때문에 대부분의 나프탈렌이 이 단계에서 제거되고, 여기서 일부의 나프탈렌을 함유하고 있는 가스는 상단부로 들어가서 나머지의 나프탈렌이 제거되게 된다.In this case, the absorption tower is operated in two stages. At the bottom, most of the naphthalene is removed at this stage because the absorbent flow rate is very high while recycling most of the absorbent oil. The remaining naphthalene is removed.
여기서는 작은 양의 흡수유가 흡수유 재생탑으로부터 공급되며 여기에 공급되는 흡수유는 그 중에 대부분의 나프탈렌이 제거됐기 때문에 미량의 나프탈렌을 제거하기에 적합하다.Here, a small amount of absorbent oil is supplied from the absorption oil regeneration tower, and the absorbent oil supplied thereto is suitable for removing trace amounts of naphthalene since most of the naphthalene is removed therefrom.
따라서 본 발명은 나프탈렌 제거공정에 있어서 흡수유에 의해 흡수되어 제거되도록하는 공정에서의 문제점인 고가의 흡수유 소비를 없애는 동시에 나프탈렌 흡수탑을 따로 두도록 하는 공정상의 복잡성을 해소하며 또한 단지 냉각에 의해 제거되도록 하고 이 때 응축된 나프탈렌은 타르에 의해 흡수되도록 하는 공정에서의 문제점인 낮은 나프탈렌 제거율과 낮은 제거율로 인해 함량이 높은 나프탈렌이 응축되어 배관등을 폐쇄하는 현상을 방지하고자 코크스가스의 온도를 높게 유지함으로써 다른 불순물의 정제효율이 낮아지는 현상을 해결함에 그 목적이 있다.Therefore, the present invention eliminates the expensive absorbent oil consumption, which is a problem in the process of being absorbed and removed by the absorbent oil in the naphthalene removal process, and at the same time eliminates the complexity of the process of leaving the naphthalene absorption tower apart and is only removed by cooling. At this time, the condensed naphthalene is maintained at a high temperature of coke gas in order to prevent the high naphthalene from condensing and closing the pipe due to the low naphthalene removal rate and the low removal rate, which are problems in the process of absorbing tar. The purpose is to solve the phenomenon that the purification efficiency of other impurities is lowered.
이와같은 목적을 갖는 본 발명은 직접식 가스 냉각기의 내측 상부에 설치되어 냉각기내에서 발생하는 물방올을 제거하기 위한 물방올 제거기와, 상기 냉각기의 내측 중앙부에 설치되어 코크스가스 정제중 부산물로 얻어지는 조경유를 투입시켜 나프탈렌 흡수촉진 및 나프탈렌 응축에 의한 냉각기의 막힘현상을 방지하기 위한 분산판과, 상기 분산판의 하부에 설치되어 조경유와 가스와의 접촉효율을 높이기 위한 충전탑과, 침전조의 입측에 설치되어 타르성분 및 나프탈렌을 함유한 조경유성분이 냉각수로부터 타르에 의해 추출해지도록 하는 타르 냉각수 접촉기와, 상기 타르 냉각수 접촉기에 설치되어, 타르를 배관의 원주방향으로 분사시켜 배관내에서 회전력을 일으키도록 하여 난류를 형성시킴으로써 냉각수와 타르와의 접촉효율을 증대시키기 위한 노즐로 이루어진 구성을 특징으로 한다.The present invention having the above object is installed in the upper upper portion of the direct gas cooler to remove the water droplets generated in the cooler, and the tank is installed in the inner central portion of the cooler obtained as a by-product during the coke gas purification Dispersion plate for preventing the blockage of the cooler due to naphthalene absorption promotion and naphthalene condensation by the injection of light oil, and the filling tower to be installed in the lower portion of the dispersion plate to improve the contact efficiency between the landscape oil and gas, and the settling tank A tar coolant contactor installed in the tar coolant contactor for extracting tar and naphthalene-containing landscape oil components from the coolant by tar, and spraying the tar in the circumferential direction of the pipe to generate rotational force in the pipe.

본 발명은 직접식 가스 냉각기(10) 상부에서 코크스가스(15)를 물과 직접 접촉시켜 냉각시키고, 냉각기(10) 중간부에 조경유{14) 투입 및 분산판(17)을 설치하고 여기에 코크스가스 정제중 부산물로 얻어지는 조경유를 투입시켜 나프탈렌 흡수촉진 및 나프탈렌 응축에 의한 냉각기(10) 막힘현상을 방지한다.In the present invention, the coke gas 15 is directly contacted with water to cool the upper portion of the direct gas cooler 10, and the landscape oil {14) is added to the middle of the cooler 10, and the dispersion plate 17 is installed therein. By inputting the landscape oil obtained as a by-product during the coke gas refining to prevent naphthalene absorption and clogging of the cooler (10) by naphthalene condensation.
가스 냉각기(10)의 기본 형태는 공탑에 물을 분사하는 형태지만 조경유(14)와 가스와의 접촉효율을 높이기 위해 조경유 분산판(17)의 바로 밑에는 충전탑(18)부분을 둔다.The basic form of the gas cooler 10 is to inject water into the tower, but in order to increase the contact efficiency between the landscape oil 14 and the gas, a packed tower 18 is disposed directly below the landscape oil distribution plate 17. .
냉각시 침적됨과 동시에 냉각수중에 존재하는 조경유(14)에 의해 용해된 상태로 존재하게 되는 나프탈렌 및 각종 타르 성분들을 제거하기 위하여 타르성분 및 나프탈렌을 함유한 조경유 성분이 냉각수로부터 타르에 의해 추출해지도록 하는 타르 냉각수 접촉기(16)를 둔다.In order to remove naphthalene and various tar components, which are deposited during cooling and remain dissolved by the landscape oil 14 present in the cooling water, the tar component and the landscape oil component containing naphthalene are extracted by tar from the cooling water. A tar coolant contactor 16 is placed.
상기 타르 냉각수 접촉기(16)의 형태는 냉각수가 흘러 빠져나오는 배관에 냉각수 배관보다 단면적이 2배가량 큰배관을 연결하고, 이 지점으로부터 타르를 투입하여 타르와 냉각수가 충분히 섞여 나프탈렌 및 나프탈렌을 함유한 조경유 성분이 타르에 의해 흡수되도록 한다.The tar coolant contactor 16 is connected to a pipe from which the coolant flows out and connects a pipe having a larger cross-sectional area twice as large as that of the coolant pipe, and injects tar from this point so that the tar and the coolant are sufficiently mixed to contain naphthalene and naphthalene. Allows landscape oil components to be absorbed by tar.
타르 냉각수 접촉기(16)에 들어가는 타르 및 냉각수의 온도는 타르의 유동성이 충분히 유지될 수 있는 온도인 50℃정도가 되도록 한다.The temperature of the tar and the coolant entering the tar coolant contactor 16 is about 50 ° C., which is a temperature at which the tar fluidity can be sufficiently maintained.
침전조(11)에서는 타르와 냉각수를 분리하고 분리된 타르는 타르탱크로 보내고 냉각수는 냉각탑(12)에서 냉각하여 가스냉각기에 재순환시킨다.In the settling tank 11, tar and cooling water are separated, and the separated tar is sent to the tar tank, and the cooling water is cooled in the cooling tower 12 and recycled to the gas cooler.
상기 냉각기(10)에 투입되는 조경유(14) 유량은 충분히 사용하여 타르의 유동성을 충분히 유지시킬 수 있도록 하고, 또한 냉각수 중에 미량으로 섞여나가는 타르가 배관내에 침전되어 배관을 폐쇄시키는 것을 방지하도록 한다.The flow rate of the landscape oil 14 introduced into the cooler 10 is sufficiently used to maintain the fluidity of the tar sufficiently, and to prevent the tar, which is mixed in a small amount in the cooling water, from being precipitated in the pipe and closing the pipe. .
또한 조경유(14)의 사용으로 인해 나프탈렌이 응고되어 배관등의 폐쇄현상을 막아주기 때문에 가스의 온도를 가능한한 많이 낮출 수 있게 해주고, 이따라 나프탈렌의 흡수효율 극대화 해주는 상승작용을 하는 효과를 가져온다.In addition, the use of landscaping oil (14) to coagulate naphthalene prevents the closing phenomenon of the pipe, etc., so that the temperature of the gas can be lowered as much as possible, thereby maximizing the absorption efficiency of naphthalene brings a synergistic effect. .
나프탈렌 흡수에 사용하는 타르는 고온의 코크스가스가 일차적으로 80℃정도로 냉각될 때 생기는 응축수와 타르를 분리하는 침전조로부터 일부를 사용한다.The tar used to absorb naphthalene is partially from the settling tank that separates the tar and condensate from the hot coke gas when it is first cooled to around 80 ° C.
냉각수 배관에 투입하는 방법은 타르를 노즐(21)을 통해 배관의 원주방향으로 분사시켜 배관내에서 회전력을 일으키도록 하여 난류를 형성시킴으로써 냉각수와 타르와의 접촉효율을 증대시킨다.In the method of injecting the coolant into the pipe, the tar is sprayed in the circumferential direction of the pipe through the nozzle 21 to generate a rotational force in the pipe to increase the contact efficiency between the coolant and the tar.
이하 본 발명을 실시예를 통하여 설명하면 다음과 같다.Hereinafter, the present invention will be described through Examples.
[실시예]EXAMPLE
유량이 약 30000N㎥/h인 코크스 가스를 직경 3m, 총 높이 26m인 가스 냉각기에 통과시키고, 냉각수 유량을 약 300㎥/h로 한 경우에 가스냉각기로 들어가는 가스온도가 80℃정도에서 배출되는 가스온도가 22℃까지 냉각되었으며, 들어가는 냉각수 온도는 18℃정도에서 50℃정도까지 상승되었다.A gas discharged at a gas temperature of about 80 ° C. when a coke gas having a flow rate of about 30000 Nm 3 / h is passed through a gas cooler having a diameter of 3 m and a total height of 26 m and a cooling water flow rate of about 300 m 3 / h. The temperature was cooled to 22 ° C and the incoming coolant temperature rose from 18 ° C to 50 ° C.
이때 조경유 투입량은 300L/h이었고, 투입위치는 지상으로부터 약 10m위치로 했다. 이 경우 가스냉각기로 들어가는 가스중 나프탈렌 함량은 1g/N㎥정도에서 0.01g/N㎥정도까지 감소되었다.At this time, the amount of landscaping oil was 300 L / h, and the injection position was about 10 m from the ground. In this case, the naphthalene content in the gas entering the gas cooler was reduced from about 1 g / Nm3 to about 0.01g / Nm3.
또한 상기 사용된 타르의 유량은 30㎥/h이었고, 타르와 냉각수와의 접촉거리는 10m정도였다. 조경유의 사용량은 1㎥/h정도였다.In addition, the flow rate of the used tar was 30 m 3 / h, the contact distance between the tar and the cooling water was about 10m. The amount of landscape oil used was about 1㎥ / h.
이와같은 본 발명은 나프탈은 가스가 냉각되면서 응축되며 이 응축된 나프탈렌은 곧바로 냉각되면서 같이 응축된 타르 및 냉각수중에 혼입시키는 조경유 성분이 녹아버리기 때문에 흡수효율을 종래의 공정보다 탁월하게 상승시킬 수 있다.In the present invention, the naphthalene condenses as the gas is cooled, and the condensed naphthalene is immediately cooled, so that the landscape oil component mixed in the condensed tar and the cooling water melts, thereby making it possible to increase the absorption efficiency more excellently than the conventional process. have.
또한 타르 냉각기의 접촉효율을 매우 상승시킨 타르냉각수 접촉기를 두었기 때문에 종래의 방법에서 사용하는 냉각기 하단부에 타르 냉각수 접촉단을 전부 냉각단으로 사용할 수 있어서 가스의 냉각효율도 크게 향상시킬 수 있다.In addition, since the tar coolant contactor which greatly increases the contact efficiency of the tar cooler is provided, all of the tar coolant contacting ends can be used as the cooling end at the lower end of the cooler used in the conventional method, thereby greatly improving the gas cooling efficiency.
이와같은 잇점은 이후 공정에서 나프탈렌 응축에 의한 막힘현상을 해결하여 주기 때문에 가스온도를 얼마든지 낮출 수가 있고, 후단에 황화수소, 암모니아, 조경유 성분을 제거하는 흡수탑에서의 흡수효율을 극대화 할 수 있다.This advantage can reduce the gas temperature by any amount because it solves the blockage caused by naphthalene condensation in the subsequent process, and can maximize the absorption efficiency in the absorption tower that removes hydrogen sulfide, ammonia and landscape oil in the latter stage. .
이상과 같은 본 발명은 코크스가스를 직접 냉각수와 접촉시켜 냉각시키고, 냉각수 중에 부산물로 발생하는 조경유를 혼입시켜 각종 배관등의 막힘현상을 방지하고, 가스 온도를 가능한 많이 낮출 수 있도록 함으로써 나프탈렌 흡수효율을 탁월하게 향상시키는 효과가 있다.In the present invention as described above, the coke gas is directly contacted with the cooling water to cool, and the landscape oil generated as a by-product in the cooling water is mixed to prevent clogging of various pipes and the like, and to lower the gas temperature as much as possible, thereby reducing naphthalene absorption efficiency. There is an effect to excellently improve.
