Description
Technical field
The present invention relates to the process of deterioration diesel oil, specifically provide a kind of processing method of power plant's backup diesel of deterioration.
Background technology
Power station generator backup diesel, deposited for a long time with the more than ten years, and in oil, color is brown, oil ageing sign
Tend to obvious.The deterioration of oil, is because diesel oil is in long storage time, the oxidization time such as undersaturated alkene containing in oil
Long, participate in plastic reaction containing for example most of sulphur of non-hydrocarbons, especially in color burn or oil after generating gummy precipitation
Mercaptan, mercaptan ethers；Nitride, either neutral nitride or basic nitrogen compound can make to generate during oil product storage and sink in a large number
Form sediment and make colour-darkening.Mechanical admixture refers to not dissolve in the oily precipitation with regulation solvent or suspension in oil or oil product,
As iron filings, fiber and some insoluble salts.For light oil, mechanical admixture can block oil circuit, promotes rubber and corrosion.In oil
Sulfur content to discharge impact also very big.
How to process with scientific and technological means and to deteriorate the performance indications of oil product and reach the standard running oil, to extend it
The service life of oil, saves fund cost, is the problem that oily business personnel are now to solve.
Require heat to more than 200 degree when originally deterioration diesel oil being processed, entered by flow processs such as high temperature distillation, extractions
Row is processed it is impossible to carry out regeneration process at the scene；And requirements of process takes the several months and just can complete.
Content of the invention
The technical problem to be solved is a kind of processing method of the power plant's backup diesel providing deterioration, Neng Gouyan
The service life of long diesel oil, cost-effective, energy-conserving and environment-protective.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of power plant's backup diesel of deterioration
Processing method, comprises the following steps：
Silica gel is added to be adsorbed by the 1-2% of deterioration diesel quality, the time is 20-24h, filters；The liquid obtaining is again
Its quality 1-2%XDK adsorbent is added to be adsorbed, the time is 45-48h, filters again；The liquid obtaining adds its quality
The desulfuration adsorbent of 5-8%, the time is 45-48h, and temperature control is at 50-80 DEG C；Finally settled, the upper strata edible vegetable oil obtaining
It is the diesel oil purifying.
Further, when adding desulfuration adsorbent to be adsorbed, temperature control is 50-55 DEG C.
Further, desulfuration adsorbent is added to carry out in adsorption process, oil product viscosity is more than 15mm2During/s, temperature control
For 70-80 DEG C.
Further, the time of described sedimentation is more than 2 hours.
Further, described XDK adsorbent is made using following raw material by weight：The sulfuric acid of 18%-22wt%
24 parts of solution, 22 parts of the aluminum sulfate solution of 6-8wt%, 26 parts of the sodium silicate solution of 4-7wt%, the ammoniacal liquor 1.35 of 21-30wt%
Part；
Its specific preparation process is：
A, sulfuric acid solution is poured in aluminum sulfate solution, adds sodium silicate solution after stirring, after stirring
It is eventually adding ammoniacal liquor, after stirring, become mixed liquor；
B, will be aging in mixed liquor suction reactor, aging temperature controls at 80 DEG C -90 DEG C, and ageing time is in 8-9 hour；
C, aging complete after dry to after service sink washing from reactor, put in baking oven baking drying, by temperature control
At 130 DEG C -140 DEG C；
D, with after phosphoric acid dip, then cleaned with water；
E, finally toasted, at 135 DEG C, baking obtained XDK adsorbent finished product after 24 hours to temperature control.
Preferably in scheme, described XDK adsorbent is made using following raw material by weight：The sulfuric acid of 19.6wt%
24 parts of solution, 22 parts of the aluminum sulfate solution of 6.91wt%, 26 parts of the sodium silicate solution of 6.05wt%, the ammoniacal liquor 1.35 of 25wt%
Part.
Further, in each adsorption process, stir 1 time within every 10 hours.
The invention has the beneficial effects as follows：
1), during desulfuration adsorbent is adsorbed, deterioration diesel oil is heated so that diesel oil can penetrate into suction
Attached dose of inner surface, if the viscosity of deterioration diesel oil is big, the temperature that can further improve heating is to 70-80 DEG C.
2) being stirred in adsorption process is also for allowing molecule be diffused into inner surface,
3) present invention is processed at ambient pressure, and heating-up temperature is relatively low, has the spy such as nontoxic, nonflammable, non-explosive
Point；And due to this process cold operation, safe and reliable.By this process mainly to the organic acid in deterioration diesel oil, particulate
The materials such as carbon, metal, sulphur, moisture and colloid are adsorbed by force, so that adsorbent is fully contacted with oil, thus except the middle deterioration thing that deoils
Matter, the waste oil indices after adsorption treatment, especially the paint film index of deterioration diesel oil, sulfur content and colourity, all reach country
Standard, and processing method is safe and reliable, the fire hidden danger that no power plant pays special attention to.
