問題点があった。(Prior Art) When raw oil is desulfurized by a direct desulfurization method, the desulfurization is performed by a hydrocracking reaction using a catalyst. In this case, if there are many magnetic particles in the feedstock oil (for example, heavy oil such as atmospheric residual oil), there are problems such as deterioration of the catalytic reaction and increased accumulation of sludge in the reaction tower. Conventionally, therefore, magnetic particles have been removed from the raw material oil using a mesh filter. However, mesh filters have problems in that they have poor ability to remove fine particles and are difficult to backwash because they are captured mechanically.

なかった。Therefore, the inventor of the present application attempted to use an electromagnetic filter. However, there was a problem in that even when the liquid was passed through the treatment object at room temperature, only a low removal rate of the magnetic particles could be obtained. Furthermore, the inventor has determined that the temperature of the feedstock oil that passes through the electromagnetic filter is within a range that does not reduce the magnetization characteristics of the magnetic particles (as shown in FIG. 2, the higher the temperature, the lower the degree of magnetization). I tried to keep it around ℃. However, it has not been possible to improve the removal rate of the magnetic particles to a level that is practical.

い。In the desulfurization system as described above, crude oil at room temperature is sent to a distillation unit 1, where gasoline, kerosene, etc. are distilled as is well known. The atmospheric residual oil (heavy oil) remaining after the above distillation is passed through an electromagnetic filter 2, where magnetic particles contained in the residual oil are removed by magnetic adsorption. In addition to iron sulfide, which is originally present in crude oil, the magnetic particles may also be mixed into residual oil due to equipment corrosion. When the residual oil is passed through the electromagnetic filter 2 as described above, the temperature of the residual oil is set to a temperature in the range of approximately 150 to 260°C. As a means for bringing the residual oil to the above temperature, if the residual oil sent out from the distillation apparatus 1 has a temperature within the above range, that temperature is used,
The remaining oil is passed through the electromagnetic filter 2 as it is. Also, if it is lower than the above range, 'N, (

が行われる。If the temperature of the residual oil is higher than the above range, it is preferable to provide a cooling device at the location (a) to cool the residual oil. Further, the heating or cooling described above may be performed within the electromagnetic filter 2 by providing a heating or cooling means within the electromagnetic filter 2. By passing the residual oil through the electromagnetic filter 2 in the above temperature range, magnetic particles such as iron sulfide are removed at a high removal rate in the filter 2. The residual oil that has passed through the filter 2 is sent to a desulfurization device 3, where it is desulfurized by a well-known direct desulfurization method. In this case, since magnetic particles such as iron sulfide are removed at a high removal rate in the am filter 2 as described above, the catalytic reaction in the desulfurization device 3 is maintained at a high level, and the accumulation of sludge in the reaction tower is extremely low. less maintained. The desulfurized residual oil that has passed through the desulfurization device 3 is sent to the next step 4, where it undergoes well-known treatment.

行うようにすれば良い。When removing magnetic particles such as iron sulfide using the electromagnetic filter 2 as described above, if the amount of magnetic particles captured by the electromagnetic filter 2 increases, the electromagnetic filter 2 is backwashed as well-known, All you have to do is repeat the iron sulfide removal process as described above.

て原料油とも呼ぶ。Next, in the above, the electromagnetic filter 2 is connected to the distillation device 1 and the desulfurization device 3.
Although an example has been described in which the electromagnetic filter 2 is installed in the front stage of the distillation device 1, magnetic particles such as iron sulfide are removed from the crude oil in advance, and the crude oil from which the magnetic particles have been removed is transferred to the distillation device 1. In this specification, the normal pressure residual oil, crude oil, etc. passed through the electromagnetic filter 2 are also referred to as feedstock oil.

一例として、硫化鉄の磁化の温度依存性を調べた結果を
示せば第２図のグラフの通りである。Next, the selection of the above-mentioned temperature of about 150 to 260° C. when passing the raw material oil through the electromagnetic filter 2 will be explained. The magnetic separation performance of the electromagnetic filter 2 largely depends on the magnetization of the particles to be captured. The graph in FIG. 2 shows the results of investigating the temperature dependence of magnetization of iron sulfide as an example of magnetic particles.

範囲が好ましい範囲であることが判明した。Further, as shown in FIG. 3, the iron sulfide contained in the raw material oil has a highly viscous substance called asphaltene 6 attached around the iron sulfide 5. The amount of asflutin attached to iron sulfide is temperature dependent. Therefore, let the magnetization value of the iron sulfide be 8, and let the value obtained by dividing the weight of asphaltene attached to the iron sulfide by the weight of the iron sulfide be B, and show the relationship between the value obtained by dividing the above A by B and the temperature. This is as shown in the graph of FIG. From this graph, it was found that the optimum temperature is about 200°C, and the preferable range is about 150 to 260°C.
次に実際の処理結果における温度と硫化鉄除去率との関
係を示せば第５図のグラフの通りである。Next, the relationship between temperature and iron sulfide removal rate in actual treatment results is shown in the graph of FIG. 5.

付けられた。Under these conditions, the magnetic field is 5 k Oes, and the iron sulfide concentration of the raw oil is 18 pp-. From this graph, the above 20
The highest removal rate is shown around 0°C, proving that it is the optimal temperature, and as the temperature gets lower or higher, the removal rate decreases, but it is around 150 to 260°C.
A high removal rate of 80 to 85% or more was obtained in this range, proving that the temperature in this range is a preferable temperature condition.

の場合である。Next, the strength of the magnetic field preferably used in the electromagnetic filter 2 will be explained. FIG. 6 shows the relationship between the strength of the magnetic field and the iron sulfide removal rate. Such a relationship is largely due to the magnetization characteristics of iron sulfide as shown in FIG. The measurement conditions in Figure 6 are that the temperature of the raw oil is 200°C, and the concentration of iron sulfide in the raw oil is 18 ppm.
This is the case.
この第６図から上記電磁フィルタ２において用いる磁界
の強さは３ｋＯｅ以上が好ましいと言える。From FIG. 6, it can be said that the strength of the magnetic field used in the electromagnetic filter 2 is preferably 3 kOe or more.

It has the feature of being able to change the state.

It has the effect of being able to remove the magnetic particles with a high removal rate.
