The method of oil.
Background technology
At present, basic product oil is refined to obtain by carrying out distillation to waste mineral oil mostly, but existing useless
Mineral oil is when refining, its easy high-temperature coking and occluding device；And when refining, burned black, colloid in waste mineral oil and
The coloring matters such as asphalitine, which are easily distilled, to be entrained out, and this easily influences the oil product of basic product oil；It is therefore desirable to give
Improve.
The content of the invention
The purpose of the present invention is to be directed to above-mentioned the shortcomings of the prior art, there is provided one kind compounding refining agent and its refining are useless
The method of mineral oil, it has the characteristics of preventing waste mineral oil occluding device and improving basic finished product oil quality.
To achieve these goals, the technical solution adopted in the present invention is：One kind compounding refining agent, its formula is with matter
Amount number calculates to be made up of following component：45~55 parts of sodium hydroxide, 7~13 parts of anhydrous sodium sulfite and sodium metasilicate 35~45
Part；During preparation, above-mentioned sodium hydroxide, anhydrous sodium sulfite and sodium metasilicate are mixed and stirred for uniformly in a kettle.
40 parts of 50 parts of the sodium hydroxide, 10 parts of anhydrous sodium sulfite and sodium metasilicate.
The method for compounding refining agent refining waste mineral oil, its step are as follows：
A, the water of refining agent and its equivalent is mixed and stirred for uniformly, to obtain solvent；
B, the solvent for accounting for waste mineral oil total amount 2~4% is added in waste mineral oil and stirred, it is molten to obtain mixing
Liquid；
C, the mixed solution obtained is put into distillation equipment and distilled, the basic crude oil colourity obtained after distillation
≤2.5；
D, basic crude oil is put into clay-filtered kettle, the basic crude oil in carclazyte refining kettle is stirred and add account for it is total
The Emathlite of amount 4~6%；
E, the temperature in clay-filtered kettle is heated to 150 DEG C, and constant temperature stirs 10~20 minutes；
F, the temperature in clay-filtered kettle is cooled to 100 DEG C, basis can be obtained by then carrying out filtering by filter
Product oil.
Solvent accounts for the 3% of waste mineral oil weight in the step b.
Mixing time in the step e is 15 minutes.
The invention has the advantages that compared with the prior art,：The compounding refining agent of the present invention can effectively prevent abandoned mine
Thing oil high-temperature coking and occluding device, while the functional group that refining agent contains with the coloring matter in waste mineral oil by forming hydrogen
Key, it is allowed to form Bridge configuration to increase the intensity of intermolecular bridge formation, and then to the carbon black in waste mineral oil, colloid, asphalitine
Trapped Deng coloring matter and form bulky grain, so these coloring matters can be prevented to be carried in distillation, improve base
The oil product of plinth product oil.
