Embodiment 1

[0017] Example 1: A compound refining agent and its method for refining waste mineral oil. The formula of the compound refining agent consists of the following components in terms of mass parts: 50 parts of sodium hydroxide, 10 parts of anhydrous sodium sulfite and metasilicon 40 parts of sodium bicarbonate; during preparation, mix the above-mentioned sodium hydroxide, anhydrous sodium sulfite and sodium metasilicate in a reaction kettle and stir evenly.

[0018] The method for refining waste mineral oil with compound refining agent, its steps are as follows:

[0019] a. Mix and dilute the prepared refining agent with water at a ratio of 1:1, and then stir it evenly with a stirring rod to obtain the required solvent;

[0020] B. Mix the obtained solvent with the waste mineral oil, the ratio is: the solvent accounts for 3% of the total waste mineral oil, after mixing, stir evenly with a stirring rod, and obtain the required mixed solution after fully mixing;

[0021] c. Put th...

Embodiment 2

[0025] Embodiment 2, the preparation steps of embodiment 2 are roughly the same as embodiment 1, and its difference is that the formula of compound refining agent is calculated by the following composition in parts by mass: 45 parts of sodium hydroxide, 7 parts of anhydrous sodium sulfite and partial 35 parts of sodium silicate; wherein, the solvent accounts for 2% of the total waste mineral oil in step b, acid clay accounts for 4% of the total base crude oil in step d, and the stirring time in step e is 10 minutes; the rest are the same as in the examples 1.

Embodiment 3

[0026] Embodiment 3, the preparation procedure of embodiment 3 is roughly the same as embodiment 1, and its difference is that the formula of compound refining agent is calculated by the following composition in parts by mass: 55 parts of sodium hydroxide, 13 parts of anhydrous sodium sulfite and partial 45 parts of sodium silicate; wherein, the solvent accounts for 4% of the total waste mineral oil in step b, acid clay accounts for 6% of the total base crude oil in step d, and the stirring time in step e is 20 minutes; all the other are the same as in the examples 1.

Abstract

The invention discloses a compound refining agent and a waste mineral oil refining method thereof. The refining agent is prepared from the following components in parts by mass: 45-55 parts of sodium hydroxide, 7-13 parts of anhydrous sodium sulfite and 35-45 parts of sodium metasilicate. The refining agent is prepared by mixing sodium hydroxide, anhydrous sodium sulfite and sodium metasilicate in a reaction kettle, and uniformly stirring. The method for refining waste mineral oil comprises the following steps: mixing the refining agent and water having equal amount as that of the refining agent; adding solvent into waste mineral oil, and uniformly stirring to obtain a mixed solution; distilling the mixed solution to obtain base crude oil; and adding acid earth into the base crude oil, stirring and filtering to obtain bas finished product oil. The method has the advantages of preventing waste mineral oil from blocking equipment and improving the quality of the base finished product oil.

Description
