Description

바이오 디젤 증류 장치 및 바이오 디젤 정제 방법Biodiesel Distillation Apparatus and Biodiesel Purification Method
본 발명은 바이오 디젤 생산 공정에서 생성되는 바이오 디젤 원액으로부터 바이오 디젤을 효과적으로 정제하기 위한 장치 및 방법에 관한 것이다. The present invention relates to an apparatus and method for effectively purifying biodiesel from biodiesel stock produced in a biodiesel production process.
일반적으로 상압에서 바이오 디젤(이하, 'BD'로 지칭되기도 함)은 300℃ 이상에서 끓지만, 300℃ 이상에서 바이오 디젤은 폴리머 형태로 변하여 특유의 성질을 상실한다. 증류 과정에서 바이오 디젤이 변성되는 것을 방지하기 위해 종래의 바이오 디젤 생산 공정에서는 절대압 기준 1 내지 2 토르 정도의 고진공으로 감압하고 약 200℃에서 바이오 디젤을 증류한다. In general, biodiesel (hereinafter also referred to as 'BD') at normal pressure boils at 300 ° C. or higher, but at 300 ° C. or more, biodiesel turns into a polymer form and loses its characteristic properties. In order to prevent biodiesel from being denatured during the distillation process, the conventional biodiesel production process reduces the pressure to a high vacuum of about 1 to 2 Torr based on absolute pressure and distills the biodiesel at about 200 ° C.
도 1은 종래의 방식으로 바이오 디젤을 증류하고 기체와 액체를 분리하기 위한 장치로서, 증발기(10)와 기액분리기(20)가 별도로 구비되어 있고, 증발기(10)와 기액분리기(20)가 연결 배관(30)을 통해 연결되어 있다. 따라서 증발기(10)에서 증발된 바이오 디젤 증기는 연결 배관(30)을 통해 기액분리기(20)로 이송되어, 바이오 디젤 증기는 기액분리기(20)의 상부로 배출되고, 바이오디젤 증기와 함께 증발되었던 바이오 디젤 액적은 기액분리기(20)의 하부에 모이게 된다. 1 is a device for distilling biodiesel in a conventional manner and separating gas and liquid, and an evaporator 10 and a gas-liquid separator 20 are separately provided, and the evaporator 10 and the gas-liquid separator 20 are connected. It is connected via the pipe (30). Therefore, the biodiesel vapor evaporated in the evaporator 10 is transferred to the gas-liquid separator 20 through the connection pipe 30, so that the biodiesel vapor is discharged to the upper portion of the gas-liquid separator 20, and has been evaporated together with the biodiesel steam. The biodiesel droplets are collected at the bottom of the gas-liquid separator 20.
연결 배관(30)을 통해 유입되는 액적에는 증류되어야 하는 바이오 디젤이 다량 함유되어 있어서 기액분리기(20)의 상부로 배출되는 바이오 디젤 증기량이 상대적으로 적어지므로 바이오 디젤 증류 효율이 낮아진다. 또한 증발기에서 증류된 바이오 디젤 증기는 연결 배관(30)을 통과하는 동안에 일부가 응축되어 기액분리기(20)의 하부로 모이게 되므로, 바이오 디젤 증류 수율이 낮아지는 결과를 초래한다.The droplet flowing through the connection pipe 30 contains a large amount of biodiesel to be distilled, so that the amount of biodiesel vapor discharged to the upper portion of the gas-liquid separator 20 is relatively low, thereby reducing the biodiesel distillation efficiency. In addition, since the biodiesel vapor distilled from the evaporator is partially condensed while passing through the connecting pipe 30 and collected at the bottom of the gas-liquid separator 20, the biodiesel distillation yield is lowered.
그 외에도, 고진공 감압 조건에서 증류하는 경우 증발되는 바이오 디젤 증기의 밀도가 낮아지므로 증기가 통과하기 위한 연결 배관(30)의 단면적이 증가되어야 한다. 즉, 연결배관의 단면적이 충분히 크지 않으면 증발기(10)와 기액분리기(20)를 연결하는 연결 배관(30)에서의 바이오 디젤 증기 유속이 과다하여 압력 손실이 커지고, 이로 인해 바이오 디젤 증발기(10)의 진공도가 약화되고, 이는 최종적으로 수득되는 바이오 디젤 증기의 품질이 저하되는 문제를 야기한다.In addition, since the density of the biodiesel vapor evaporated when the distillation under high vacuum decompression conditions is lowered, the cross-sectional area of the connecting pipe 30 for passing the steam should be increased. That is, if the cross-sectional area of the connecting pipe is not large enough, the biodiesel vapor flow rate in the connecting pipe 30 connecting the evaporator 10 and the gas-liquid separator 20 is excessive, resulting in a large pressure loss, and thus the biodiesel evaporator 10. The vacuum degree of is weakened, which causes a problem that the quality of the biodiesel vapor finally obtained is degraded.
나아가, 연 5만톤 생산 기준으로 바이오 디젤을 증류하려면 연결 배관(30)의 직경(D2)이 1500㎜ 이상이어야 하는데, 증발기(10)의 외경(D1)이 800㎜에 불과하기 때문에 연결 배관(30)과 증발기(10)를 연결하기 어려운 설계상의 문제가 있다. 즉, 연결 배관(30)에서의 유속을 감소시키려면 연결 배관(30)의 직경(D2)을 키워야 하지만, 이 경우 연결 배관(30)의 직경(D2)이 증발기(10)의 외경(D1)보다 커져서 증발기(10)의 제작이 불가능하게 되고, 연결 배관(30)의 직경(D2)을 증발기(10)의 외경(D1)에 맞추면 배관 내에서 초음속 유동이 발생하여 장치 자체에 손상을 초래할 우려가 있다. 반대로 증발기(10)를 연결 배관(30) 직경(D2)에 맞추면, 증발기(10)의 가열튜브의 길이가 작아져서 충분한 가열 시간을 확보할 수 없기 때문에 바이오 디젤 증류가 어려워진다.Furthermore, in order to distill biodiesel on a production basis of 50,000 tons per year, the diameter D2 of the connection pipe 30 should be 1500 mm or more, and the connection pipe 30 because the outer diameter D1 of the evaporator 10 is only 800 mm. ) And the design problem is difficult to connect the evaporator 10. That is, in order to reduce the flow rate in the connecting pipe 30, the diameter D2 of the connecting pipe 30 should be increased. In this case, the diameter D2 of the connecting pipe 30 is the outer diameter D1 of the evaporator 10. It becomes larger and it becomes impossible to manufacture the evaporator 10, and when the diameter D2 of the connection pipe 30 is matched with the outer diameter D1 of the evaporator 10, a supersonic flow will generate | occur | produce in a piping, and it may cause damage to the apparatus itself. There is. On the contrary, when the evaporator 10 is matched to the diameter D2 of the connecting pipe 30, the biodiesel distillation becomes difficult because the length of the heating tube of the evaporator 10 is small and sufficient heating time cannot be secured.
