Description

원유(原油)의 신(新)처리방법New treatment method of crude oil

도면은 본 발명에 관한 1실시예의 플로우 차아트.Figure 1 is a flow chart of one embodiment according to the present invention.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1,4 : 원료탱크 2 : 수소하 분리탈황장치(HSP)1,4: Raw material tank 2: Separation desulfurization unit under hydrogen (HSP)

3 : 상압(常壓) 증류탑(topper)3: atmospheric distillation column (topper)

본 발명은 원유를 수소화(化)분리·탈황하는 방법 즉, HSP(Hydrostripping Process)의 개량방법에 관한 것과 동시에 보통의 상압 증류탑의 효율적인 이용방법에 관한 것이다.The present invention relates to a method for hydrocracking and desulfurizing crude oil, that is, a method for improving the HSP (Hydrostripping Process) and at the same time an efficient method for using a normal atmospheric distillation column.

현재에 있어서, 원유는 탈염시킨 후 상압증류탑에 도입되어 분리·정제되어 있으나, 원유는 반드시 전부, 상압증류탑에 있어서 최종제품으로는 되고있지 않을 뿐만아니라 원유의 종류에 따라서 변환운전을 하고, 그때문에 상압증류탑의 가동률을 떨어뜨리고 있었다. 이것은 원유의 종류에 따라 상압증류탑에 있어서 그대로 제품으로되는 것, 안되는 것이 존재하기 때문이며, 최종제품으로 하기 위하여 각종의 수소화처리가 행해지고 있는 것이 실태이다. 특히 경질·양질원유는 그대로 제품으로되는 것이 많은 반면, 중질·고유황 원유등은 이후의 처리를 필요로하기 때문에, 상압 증류탑에서의 상기한 종류의 원유의 동시운전에 의한 정제는 비경제이기 대문에 변환운전을 행하고 있었다.At present, crude oil is desalted and introduced into an atmospheric distillation column to be separated and refined. However, not all crude oil is necessarily the final product in the atmospheric distillation column, and the conversion operation is performed according to the type of crude oil. The operation rate of the atmospheric distillation tower was falling. This is because in the atmospheric distillation column depending on the type of crude oil, there are some products which are or cannot be used as they are, and in fact, various hydrogenation treatments are carried out in order to obtain a final product. In particular, since light and high quality crude oils are often produced as they are, heavy and high sulfur crude oils require further processing, and thus, refinement by simultaneous operation of the above-described types of crude oil in an atmospheric distillation column is not economical. The conversion operation was performed.

본 발명은 이들의 문제를 해결하고, 동시에 상압증류탑에서의 최종제품을 증가시킴과 아울러 상압증류탑의 가동률을 향상시키는 방법을 제공하는 데에있다. 즉 중질원유, 고유황 원유, 고파라피닉 원유등 수소화처리 유분(留分)이 많은 원유는 사전에 수소하 분리 탈황장치를 통하여 중간유분(Middle Distillate)+라이터(Lighter Fraction)를 탈황처리하고, 그 제품의 증류탑으로서 상압증류탑을 이용하여 분리정제한다.The present invention is to solve these problems, and at the same time to provide a method for increasing the final product in the atmospheric distillation column and at the same time improve the operation rate of the atmospheric distillation column. In other words, heavy crude oil such as heavy crude oil, high sulfur crude oil, high paraffinic crude oil, and the like, the crude oil having a large amount of hydrogenated oil is desulfurized by the middle distillate + lighter fraction through a hydrogen-separated desulfurization device. The product is separated and purified using an atmospheric distillation column as a distillation column of the product.

상기한 수소하에서 분리탈황처리한 유분을 그 상압증류탑에 직접통하고 있는 경질·양질원유와의 유뷴과 혼합증류시키는 것에 의하여 최종제품을 증가시키는 것이다. 여기서 말하는 수소하 분리탈황장치로부터의 중간유분+라이터는 탈황처리되어 있기 때문에 경질·양질 원유로부터의 중간유분+라이터보다 양질내지는 손색이 없는 것이며, 따라서 전체적으로 보아 상압증류탑에서의 최종제품은 중량하여서 그 가동률의 향상에 관련되는 것으로 된다. 여기에서 수소하 분리탈황장치에 대하여 설명하면, 본 장치는 HSP라고도 불리우며, 국내외적으로 이미 알려진 것이나, 원유에 수소를 첨가하여 고온·고압하에서 분리하여 경질유분을 첨가수소와 함께 탈황하는 공정이며, 본 방법은 수소화처리를 필요로 하는 유분이 많은 원유의 분리(중간유분+라이터와 증질유분으로 분리)탈황에 이용하는데에 적합한 방법이다. 분리된 중질유분은 다른 적당한 장치로 보내어지게 된다. 즉 본 발명에 의한 원유의 신처리방법이라함은 위치에서 설명한 수소하 분리탈황방법과 기존의 상압증류탑을 경유하는 방법을 종합적으로 결합시킨 것으로서, 이 방법에 의하여The final product is increased by mixing and distilling the oil separated and desulfurized under the above-mentioned hydrogen with the oil and light oil which are directly passed through the atmospheric distillation column. Since the intermediate oil + lighter from the hydrogen-separated desulfurization unit here is desulfurized, it is inferior to the middle oil + lighter from light and high quality crude oil. It will be related to the improvement of the utilization rate. Herein, a description will be given of a separation desulfurization apparatus under hydrogen, which is also known as HSP, and is known at home and abroad, but is a process of desulfurizing light oil with additional hydrogen by adding hydrogen to crude oil and separating it under high temperature and high pressure. This method is suitable for use in the desulfurization of oily crude oil (medium oil + lighter and steam oil) requiring hydrogenation. The separated heavy oil is sent to another suitable device. In other words, the new treatment method of crude oil according to the present invention is a combination of the hydrogen separation and desulfurization method described in the above section and a conventional method of passing through an atmospheric distillation column.
