含んだ原料油を処理すると、著しく汚れが増大する。In the petroleum refining process, there are processes dedicated to atmospheric distillation equipment, hydrodesulfurization equipment, and catalytic reforming equipment, and each raw material oil is heated, cooled, and heated until each petroleum product is produced from petroleum.
Decomposition, separation, etc. are performed repeatedly. In these devices, when heated in a preheating heat exchanger, heating furnace, etc., the raw material oil undergoes thermal denaturation to generate sludge, which adheres to the vessel walls and generates dirt. Oxygen is dissolved in the feedstock, especially when each feedstock is transported by ship or once stocked in an intermediate tank, but when feedstock containing oxygen is processed, it becomes extremely polluted. increases.

Antioxidants, metal deactivators, dispersants, etc. are used to prevent stains caused by XX oil extraction that occur in piping, etc.
Antifouling agents that combine these are used. Polyalkenyl succinimide is widely known as a typical conventional stain inhibitor, but there are also stain prevention agents containing copolymers of alkyl- or alkenyl-substituted organic carboxylic acids and polyalkylene polyamines, and phosphites. antifouling agents (e.g., Japanese Patent Publication No. 46-6503), and antifouling agents containing reaction products of polyamines and succinic acid compounds, phenolic compounds, and N,N'-disalicylidene-1,2-propanediamine (e.g., Japanese Patent Publication No. 60-543).
No. 27) is known.

る。However, conventional antifouling agents such as polyalkenyl succinimide can manage to suppress staining when the degree of staining is low, but as the degree of staining increases, the antifouling effect becomes less effective. □′-′” Since the composition of Japanese Patent Publication No. 46-6503 contains a polyalkylene polyamine, the amine decomposes under the temperature during petroleum refining. The amines produced in this way poison the catalysts used in petroleum refining, so they cannot normally be used, and even if they are used, they are extremely limited to sunset scenes.

問題点があった。In addition, in the composition of JP-A No. 60-54327, the reaction product of polyamine and succinic acid is oil-insoluble, requiring special measures for dosing, and the phenol compound is generally 150
In the temperature range above ℃, decomposition begins and there are problems such as poor effectiveness.

。The antifouling agent of the present invention can be used to treat all oil refining process systems where fouling occurs, but in particular crude oil atmospheric distillation equipment, naphtha, kerosene and gas oil hydrodesulfurization equipment, and FC' A feed oil heat exchanger system such as C is suitable for the treatment. The method for using the antifouling agent of the present invention is to dissolve the antifouling agent of the above formulation in a hydrocarbon solvent and continuously inject the solution in front of a heat exchanger where fouling occurs in an oil refining process system.
汚れ防止剤の使用濃度は１〜５００ｍｇ／ｋｇ（対処理
オイル）程度である。The concentration of the antifouling agent used is approximately 1 to 500 mg/kg (based on treated oil).

ョンによるスラッジ生成を抑制するものと推測される。When the antifouling agent of the present invention is added, the glycidyl ethers suppress the formation of sludge and at the same time disperse the sludge, thereby providing an excellent antifouling effect. At this time, it is assumed that the glycidyl ethers react with organic acids generated during the process of oxidative deterioration of hydrocarbons, thereby suppressing the formation of sludge due to subsequent polymerization.

なる。In general, hydrodesulfurization equipment that processes naphtha, kerosene, etc. containing oxygen, iron, and copper can only be operated for a few months without the addition of antifouling agents due to fouling, and existing products such as polyalkenyl succinimide Even when the antifouling agent of the present invention is used, it can be operated for only about half a year at most, but with the antifouling agent of the present invention, it can be operated for about one year.
このため熱交換器での汚れが軽減でき、装置の安定運転
と省エネルギーが可能となる。Therefore, contamination in the heat exchanger can be reduced, making it possible to operate the device stably and save energy.

して汚れ防止剤無添加の場合の結果を併記する。FIG. 1 is a block diagram showing the heating block test method, in which a test tube 9 and a heater 10 are set in the first and second heater blocks 7.8 whose outlet temperature can be controlled, and a sample 1 is pumped from a sample tank 11 by a pump 12. It is passed at a constant flow rate, circulated through the cooler 13, and the dirt adhering to the test tube 9 is measured. 14 is a pressure gauge, and 15 is a pressure holding valve. At this time, the sample flow rate was 1,012/hr, the temperature of the first heater block 7 was 150°C, the outlet temperature of the second heater block 8 was 250°C, the pressure was 20kg/aJ, and the dissolved oxygen was 130mg.
/kg, iron 1, 0mgIQ, copper 0.05n+g/Q,
The test time was 20 hours, and the results are shown in Table 1. As a comparative example, the results in the case where no antifouling agent was added are also shown.
