Embodiment 1

[0122] Add 1-methylnaphthalene to the heavy oil that is mined or / and exported to reduce the viscosity of the heavy oil, thereby reducing the flow resistance of the heavy oil, and making the heavy oil flow smoothly;

[0123] Tests show that: adding the 1-methylnaphthalene to the heavy oil can effectively reduce the viscosity of the heavy oil (see the test data in Table 3 of the test results);

Embodiment 2

[0125] Repeat Example 1, except that: in order to prevent the 1-methylnaphthalene from generating crystals, solids or solidification in a low temperature environment, fusel oil is added to the 1-methylnaphthalene;

[0126] The fusel oil refers to any one of fusel oil from the by-product of alcohol production by fermentation and fusel oil from the by-product of butadiene production by alcohol, or a mixture of them in any ratio;

[0127] Any one of the fusel oils is a commodity or can be purchased from the market;

[0128] The added fusel oil ensures that the 1-methylnaphthalene is always liquid in a low temperature environment, and does not produce crystals, solids or solidification.

Embodiment 3

[0130] Repeat Example 1, except that: in order to prevent the 1-methylnaphthalene from generating crystals, solids or solidification in a low temperature environment, a special organic solvent is added to the 1-methylnaphthalene;

[0131] The special organic solvent refers to any of alcohols (such as octanol, isoamyl alcohol, etc.), glycol derivatives (such as ethylene glycol butyl ether, diethylene glycol butyl ether, diethylene glycol ethyl ether, etc.) One or a mixture of any two or more of them in any ratio;

[0132] Any one of the special organic solvents is a commodity or can be purchased from the market;

[0133] The added special organic solvent ensures that the 1-methylnaphthalene is always liquid in a low temperature environment, and does not produce crystals, solids or solidification.

Abstract

The invention discloses application of methylnaphthalene in lowering viscosity of thickened oil, which comprises application of 1-methylnaphthalene in lowering viscosity of thickened oil and the specific implementation steps, 2-methylnaphthalene in lowering viscosity of thickened oil and the specific implementation steps and mixed methylnaphthalene in lowering viscosity of thickened oil and the specific implementation steps. The invention enlarges the application method of methylnaphthalene, clearly demonstrates the specific application method of using methylnaphthalene to lower viscosity of thickened oil, solves the problems of great load and power consumption, frequent machinery accidents, high surface line return pressure, and the like of an oil extractor during extracting and outwards transporting thickened oil in the background art, and can effectively lower viscosity of thickened oil and reduce extraction and outward transportation cost of thickened oil.

Description

Technical field [0001] The invention relates to the application field of methyl naphthalene, in particular to the application of methyl naphthalene in reducing the viscosity of heavy oil. Background technique [0002] The current public information shows that: methyl naphthalene is mainly used to produce disperse dye additives (dispersants), and can also be used as heat carriers and solvents, surfactants, sulfur extractants, and can also be used to produce plasticizers and fiber dye additives It can also be used to determine standard fuels for the alkane number and cetane number. [0003] China University of Petroleum Press, the first printing of the first edition of "Oil Field Chemistry" in July 2000, stated in the bottom 5-6 lines on page 175, "Due to the heavy oil, the pumping unit has a large load and a large power consumption. Frequent mechanical accidents and high back pressure of ground pipelines have brought difficulties to the exploitation and export of heavy oil.” Theref...
