Abstract
The present invention discloses fuel oil prepared by modifying coke tar residue in a coke-oven plant and a preparation method thereof. The present invention solves the technical problem of tar oil residue pollution of coke-oven plants and modifies the tar oil residue into fuel oil, and the present invention provides a preparation method of fuel oil. The present invention is characterized in that the fuel oil prepared by modifying the tar oil residue has the components of 60 to 90 wt% of tar oil residue, 5 to 30 wt% of diluent A, 0.0 to 10 wt% of diluent B and 0.05 to 0.5 wt% of stabilizing dispersant. The present invention has the modification method that the tar oil residue and the diluent A are conveyed to a raw material processing tank to be mixed, the stabilizing dispersant is added for modifying quality and grinding, the diluent B is subsequently added and ground, and then oil is filled in an oil tank for being stored. The present invention has the advantages that the tar oil residue is industrial waste residue of the coke-oven plants, the grain sizes of solids in the residue, such as coke powder, coal powder, etc., are decreased by decreasing the viscidity of the tar oil residue, asphaltene in the residue is dissolved so as to avoid oil-water separation, oil sludge precipitation, etc., and the present invention has pumping application effect and can satisfy fuel requirements of industrial furnaces.
Description
Relate to the field and the present invention relates to the waste oil residue processing technology field, particularly coke-oven plant's coke tar refuse upgrading made fuel oil and preparation method thereof.
Technical background is present, and coke-oven plant's coke tar refuse is the thick solid slag that is adsorbed with coal tar that produces in the production process, mainly is made up of polycyclic aromatic hydrocarbons hydrocarbon polymer, phenol and naphthalene and coal dust, coke powder.Under the normal temperature extremely thickness be difficult to direct utilization.Because some toxicant in its composition, as far back as 1976, U.S. environment administrative authority was just definite, and coke tar refuse is indusrial toxic, harmful waste residue, and the storage and the processing of this class waste residue proposed strict restriction.
For many years, owing to lack corresponding coke tar refuse process and utilization technology, domestic coke-oven plant adopts following two kinds of approach that it is disposed usually: (1) directly sneaks into coking in the coke making and coal blending; (2) free or extremely low price transports the rural area, suburb to, uses as earth kiln fuel.First kind of approach makes coke quality produce fluctuation because the coke tar refuse thickness is difficult to batching accurately, and the thermal load of coke oven is improved.Therefore most of coke tar refuse is disposed by second kind of approach.And this method has not only been wasted resource but also polluted environment because coke tar refuse air storage and incomplete combustion pollute again the suburb surrounding enviroment.Therefore, still be environment protection and social benefit aspect no matter from economic benefit of enterprises, carry out the processing and utilization of coke tar refuse, all be necessary.
Summary of the invention technical problem to be solved by this invention is the pollution at coke-oven plant's coke tar refuse, with its coke tar refuse upgrading made fuel oil and preparation method thereof.Characteristics such as the oil fuel that this coke tar refuse upgrading is made is the fluid fuel with good combustionproperty, and its technology has that technological process is simple, less investment, floor space are little are industrial residue process and utilization technologies highly significant.
Usually, solid phase partly is that toluene insolubles accounts for 40%～50% in the coke tar refuse, and all the other are coal tar.Wherein moisture is 5%～11%, and ash content is 4%～6%, and full sulphur is 1.6%～2.5%; The density of anhydrous tar slag is 1.29～1.35g/cm
3Each coke-oven plant of coke tar refuse quality and yield is because of the different difference to some extent of shove charge coal ature of coal, fineness and coking operation technology.The coke tar refuse quality index (seeing Table 1) that table 1 scrapes for certain coke-oven plant's mechanize tar clarifying tank.
Table 1 coke tar refuse quality index
| Moisture, % | Ash content, % | Volatile matter, % | Thermal value (Qb, ad), MJ/kg | Toluene insolubles, % |
| 8.4 | 4.2 | 50.1 | 29.78 | 50.53 |
As can be seen from Table 1, the solid contents of this coke tar refuse is very high, and toluene insolubles is up to 50.53%; Thermal value is 29.78MJ/kg; Moisture, ash content, volatile content are respectively 8.4%, 4.2% and 50.1%.
Coke-oven plant's coke tar refuse upgrading made fuel oil is characterized in that coke tar refuse upgrading made fuel oil composition consists of: coke tar refuse accounts for that weight percent (as follows) 60%～90%, thinner A account for 5%～30%, diluent B account for 0%～10% and stable dispersant account for 0.05%～0.5%.
Thinner A is: coal tar, revivifier Residual oil (Residual oil between coke-oven plant's recovery vehicle) or carbolineum, and diluent B is: crude benzol or heavy benzol; Stable dispersant is: the C of 10%-60%
6 ~ 18The compound of the sorbitan monooleate of alkylphenol polyoxyethylene, 28%-90% and 0%-12% alkyl sodium sulfonate.
Described coke-oven plant coke tar refuse upgrading made fuel oil preparation method is characterized in that:
1, getting coke tar refuse is that main raw material accounts for 60%-90%, and coke tar refuse is by bucket elevator charging feed treatment trough, and thinner A accounts for 5%-30% and squeezes into the raw material treatment trough with volume pump; Mixture under 20～95 ℃ temperature, is handled back adding stable dispersant through 0.1～4 hour stirring viscosity reduction and is accounted for 0.05%～0.5% modifiedly in the raw material treatment trough, then its mixture is sent into grinding machine for grinding;
2, reduce the granularity of solid particulate, mixture was ground 0.5～5 hour, add diluent B by volume pump in shredder and account for 0%-10%, wherein solid particulate≤200 orders account for more than 98%;
3, shredder discontinuous operation.Each milling time 0.5～5 hour.Shredder is shut down, and drains the oil in ramp pan, after oil pump, strainer filter, sends into oil tank and stores.
The invention has the beneficial effects as follows that coke tar refuse is coke-oven plant's industrial residue; By reducing coke tar refuse viscosity, reduce the wherein granularity of solids such as coke powder, coal dust, dissolving bituminous matter has wherein been avoided oily water separation and greasy filth precipitation etc., it is reached have the pumping effect, satisfies the requirement of industrial furnace fuel.Prepared coke tar refuse oil fuel viscosity 50～330mPa.s (80 ℃), moisture≤8.0%, ash content≤5.0%, sulphur content≤1.06%, density is 1.1～1.3g/cm
3, thermal value is 29.26～37.62MJ/kg, flash-point 〉=105 ℃, and coke tar refuse oil fuel is under 80 ℃～85 ℃ temperature, and precipitation and oily water separation phenomenon do not take place in 20 days or longer time.
