Detailed description of the invention
Carry out as described below in conjunction with jet fuel regeneration economic benefits and social benefits absorption distillation process system flow chart:
1, jet fuel to be regenerated is extracted out by raw material pump 1 from head tank 2, sends into adsorptive rectification tower 7 feed zone after pump pressurizes twice heat exchange;
2, top gaseous phase material enters return tank of top of the tower 4 after air cooler 6 and condensate cooler 5 condense cooling, and reflux pump 3 extracts liquid of top of the tower phase materials out from return tank of top of the tower, and a road therein is sent into tower top and refluxed, and overhead product tank 13 is delivered on another road;
3, base oil is delivered to adsorb blender 9 by column bottoms pump 8, heating furnace pump 10 is extracted the tower base oil containing jet fuel regeneration Special adsorbent out from absorption blender and is delivered to heating furnace 11, furnace outlet material one tunnel is sent at the bottom of economic benefits and social benefits adsorptive rectification tower, cooler 14 at the bottom of heat exchanger 12 at the bottom of another Lu Jingta and tower enters bottom product tank 15, the material pumping of bottom product tank, to filtration system, removes adsorbent and obtains the bottom product without adsorbent.
4, a line pump 16 Extract phase materials in the middle part of economic benefits and social benefits adsorptive rectification tower rectifying section, via line heat exchanger 17 and a line cooler 18, sends into a line products pot 19 after its heat exchange and cooling.
Backflow makeup oil is introduced through return tank of top of the tower when 5, driving.
The preparation method of described adsorbent:
With Anhydrite as raw material, through roughly selecting, remove sandstone and Organic substance, then dried, making moisture percentage content below 10, crushed after being dried to 200 mesh, through 15% sulphuric acid by solid-to-liquid ratio 1:2.5, activation temperature 95 DEG C, soak time is acidified for 8 hours, separates solid-state, washing after acidifying, be washed till sulfuric acid content≤0.2%) after carry out second time be dried, packaged as jet fuel reproducing adsorbent.
Can remove, by economic benefits and social benefits absorption, heavy constituent, colloid, deposit and the additive that jet fuel is formed through nozzle test, obtain the blending component oil of jet fuel;
Blend component oil cuts specific fractions, overhead product, bottom product and a line product through essence gold-plating, specific fraction is added additive in proportion, becomes the jet fuel met the technical standards.
Know-why illustrates:
Showing through related data investigation, jet fuel is after nozzle test, and the character of key component does not degenerate but becomes more preferably in addition to additives.Jet fuel, after nozzle test, can cause the loss of light component, and the consumption of chemical reaction occurred is naphthalenes, tetrahydronaphthalene, alkene；In the case of temperature is higher, non-hydrocarbon compound is easiest to aoxidize, and non-persistent hydrocarbon oxidation plays the effect of initiator, and oxidation reaction product is aggregated, condensation ultimately forms sediment.Therefore the jet fuel after nozzle test, retained after removing sediment and impurity is ideal composition cycloalkane and the isoparaffin of jet fuel.Certainly also having a small amount of alkene under the conditions of nozzle test to generate, alkene is the undesirable components of jet fuel.
Defining title and the addition of additive in the annex of jet fuel GB6537-2006, in addition to waterproofing agent, the addition of other additives is the most fewer, and character is the most more stable.Therefore, less on the impact of jet fuel ideal composition by the change of additive character after nozzle, relatively big on undesirable components impact, even generate heavy constituent, colloid and deposit.
If heavy constituent, colloid, deposit and the additive component of itself that jet fuel is formed when nozzle test can be removed, reasonable jet fuel blend component will be obtained, prove that by the recovery of jet fuel be feasible.
Jet fuel reproducing adsorbent is to antioxidant 2,6-ditertbutylparacresol, antiwear additive T1602 turpentole aphthenic acids, anti-freezing agent diethylene glycol dimethyl ether, matal deactivator N, N bis-salicyl-1, the additives such as 2 propanediamine and heavy constituent, colloid, deposit have selective absorption effect, and more weak to jet fuel ideal composition cycloalkane and isoparaffin absorbability, thus realize additive and heavy constituent, colloid, deposit separate with jet fuel ideal composition through special process.
