Description
Technical field
The present invention relates to energy field, being specifically related to a kind of is novel slurry-base fuel oil and the production method and the device of main raw material with pitch, refinery coke.
Background technology
Because skyrocketing and the lighting of petroleum products structure of crude oil price, China's oil fuel output sharply reduces, and the domestic economy development is very fast, and the oil fuel demand is constantly risen.The glass stove producer etc. that with heavy oil is main fuel presses for and uses substitute energy cheaply under the pressure of cost pressure.Refinery coke is the low value-added product after the crude oil processing.Its annual production surpasses 1,000 ten thousand tons, and supply exceed demand, and the source is sufficient, and price is low.
The substitute of heavy oil mainly contains coal water slurry, the burnt slurry of water, coal oil mixture, oil coke slurry, coal tar oil fuel (asphaltum oil) etc. at present, generally often sees with coal water slurry, the burnt slurry of water.The used coal water slurry of glass stove, the burnt slurry of water require the ash content of coal or refinery coke, sulphur content low, and simultaneously because moisture height, calorific value is lower, and life-time service has certain infringement to body of heater; Utilize fat coal to make coal oil mixture, cause the wasting of resources; Coal tar oil fuel is limited by industrial scale, and output can not be flexible and changeable.
Summary of the invention
The object of the present invention is to provide a kind of novel slurry-base fuel oil, utilize low value-added refinery coke, be mixed with, thereby improve the output of oil fuel, reduce the cost of oil fuel with pitch and carbolineum.
Another object of the present invention is to provide the production method of above-mentioned novel slurry-base fuel oil.
The present invention also provides the modulating device for preparing above-mentioned novel slurry-base fuel oil.
A kind of slurry-base fuel oil is made up of following materials in parts by mass: 45～80 parts of pitch and carbolineum mixture, 20～50 parts of refinery cokes, 0～10 portion of viscosity-depression agent, 0.1～2 part stablizer;
Pitch of the present invention and carbolineum are that tar distillation produces.In pitch and the carbolineum mixture, bituminous quality percentage composition is 50%～75%.Pitch can be selected coal-tar pitch or petroleum pitch for use.
Stablizer of the present invention is a tensio-active agent, plays dissemination.Can select for use as tween 80, wooden sodium, cetyl trimethylammonium bromide, polyoxyethylene-type nonionogenic tenside, synthetic NEW type negatively charged ion fragrant tensio-active agent or their mixture.The polyoxyethylene-type nonionogenic tenside can be selected alkylphenol polyoxyethylene for use.
Viscosity-depression agent of the present invention is solvent oil or the raffinate that produces in tar or the refining of petroleum, product from tar processing has heavy residual stocks, dephenolize oil, heavy benzol, carbolineum, flash oil or its mixture, from the product of refining of petroleum diesel oil, heavy oil or its mixture is arranged.
The production method of this class novel slurry-base fuel oil comprises the steps:
Pitch and carbolineum are pressed (50%～75%): the mass ratio of (50%～25%) mixes, be heated to 90 ℃～120 ℃, with granularity is that the refinery coke of 1 μ m～1000 μ m mixes, and adding stablizer and viscosity-depression agent, the mass ratio of the mixture of its medium pitch and carbolineum, refinery coke, viscosity-depression agent and stablizer is (45～80): (20～50): (0～10): (0.1～2).
Be used to produce the modulating device of this novel slurry-base fuel oil, comprise the transferpump, preparation vessel, mixing pump, emulsify at a high speed shears and the storagetank that connect successively, be provided with well heater and agitator in the preparation vessel, and be connected with volume pump, header tank, coke powder hopper.
In the production, transferpump is pitch and carbolineum input preparation vessel, and by heater heats to certain temperature.Add viscosity-depression agent by header tank, volume pump adds stablizer; Or by volume pump adding viscosity-depression agent, header tank adds stablizer.Refinery coke jaw crusher fragmentation, suitably dry back is milled to certain fineness in ball mill or rod mill, lean on transfer roller or manually add the coke powder hopper, progressively adds preparation vessel again.Be deployed into novel slurry-base fuel oil through agitation as appropriate, shearing.
By aforesaid method and equipment, the resulting product in allotment back by measuring viscosity, density, calorific value, sulfur-bearing, ash content, stability etc., makes it satisfy customer requirements.The invention has the beneficial effects as follows that the refinery coke that will be difficult to effectively utilize is modulated into slurry-base fuel oil, can reduce cost, satisfy glass stove user's needs.
