ジである。2. Description of the Related Art Crude oil used in Japan is generally used after being stored for a long time in a storage tank of several tens of thousands to 100,000 kiloliters. National reserves are increasing, storage tanks are getting bigger and storage periods are long. In this situation, a problem is sludge that gradually accumulates at the bottom of the storage tank.

いる。[0003] This sludge is generally a complex mixture of wax, resin, asphaltenes, and other high-molecular substances in crude oil, and may reduce the storage capacity of a tank or clog oil feed pipes and pumps. This is a major problem when storing crude oil. As a method for preventing the sludge from accumulating, generally, a method is employed in which the liquid is stirred by a mechanical method using a stirrer or the like to prevent sedimentation and sedimentation of the sludge.

ージタンクには法定点検が必要となっている。However, it is very difficult to disperse the crude oil sludge in these huge tanks by stirring, and it is not economically advantageous. Therefore, a method of stably dispersing sludge by adding a small amount of an oil-soluble dispersant has been studied.
(Japanese Patent Publication No. 62-1435). However, no drug has been found that has a wide range of effects on various types of crude oil produced around the world. Furthermore, in recent years, legal inspections of crude oil storage tanks have become necessary.

０３８号公報に詳細に述べられている通りである。That is, the present invention is a method for effectively dispersing sludge present in crude oil by adding 10 to 5000 ppm of a polyamide represented by the general formula (1) to crude oil. [In the formula, when one of R 1 and R 2 is a hydrogen atom, the other is a saturated aliphatic hydrocarbon group having 6 to 30 carbon atoms, and both R 1 and R 2 are saturated aliphatic hydrocarbon groups. When it is a hydrogen group, the total number of carbon atoms of R 1 and R 2 is 6 to 30, and X 1 and X 2
One is a -NY 1 Y 2 group (Y 1 and Y 2 each represent an aliphatic hydrocarbon group having 10 to 28 carbon atoms), and the other is a -OM group (M represents hydrogen, an alkali metal, or an amine) , N represents a positive number of 2 to 30].
