Abstract
The present invention relates to a method for extracting an acidizer and nitrides from denitrification residue generated from basic lubricating oil production, which comprises: a. a reagent A and a reagent B are stirred and mixed with denitrification residue to obtain the denitrification residue mixture; the reagent A is a diffluent substance for nitrides, and the reagent B is a demulsifying agent; b. a water solution with a reagent C is added to the denitrification residue mixture, and the mixture is stirred, precipitated and separated to obtain a separated liquid A and a separated liquid B; c. the reagent A is distilled out of the separated liquid A to obtain the nitrides, and water and the reagent C are distilled out of the separated liquid B to obtain the acidizer with the reagent B. The method has the advantage that the denitrification residue can be divided into the acidizer and the nitride.
Description
The present invention relates to the petroleum refining field, more particularly, provide a kind of treatment process denitrification residue.
At present, each refinery of China, the denitrification residue that produces in the process of producing lubricant base extremely are difficult for handling, and pollute when garbage emission can produce environment.
The object of the present invention is to provide a kind of treatment process of denitrification residue, it can effectively extract acidizer and nitride in the denitrification residue, suitability for industrialized production environmentally safe.
From production basis lubricating oil denitrification residue, extract the method for acidizer and nitride, it is characterized in that: a, use reagent A and reagent B and denitrification residue, according to denitrification residue: reagent A: the part by weight of reagent B=100: 10-100: 0-10, under 60 ℃-100 ℃ temperature condition, stir and merge, obtain the denitrification residue fusions; Reagent A is the lyotrope of nitride, and reagent B is an emulsion splitter;
B, in the denitrification residue fusions, add the aqueous solution contain reagent C, according to denitrification residue: the aqueous solution=100 that contain reagent C: the part by weight of 100-300, stirring, sedimentation, separate then and obtain two kinds of parting liquids of first, second, first liquid is the fusions of nitride and reagent A, and second liquid is the aqueous solution of acidizer, reagent B, reagent C; Reagent C is a solubilizing agent, is 2-50% in water capacity liquid weight concentration;
C, from first liquid, steam reagent A and obtain nitride, from second liquid, steam the acidizer that moisture content, reagent C obtain containing reagent B.Reagent A is any in following and composition thereof, benzene,toluene,xylene, trimethylbenzene, sherwood oil, solvent oil, gasoline, diesel oil, kerosene, molecular sieve essential oil, solvent treatment extract out oil, coal tar, chemical industry with aromatic hydrocarbon oil, make olefin cracking tail oil, alkylation tail oil; Reagent B is any in following: sulfuric acid, hydrochloric acid, nitric acid and water-soluble salt thereof; Reagent C is any one in the following material: methyl alcohol, ethanol, ethylene glycol, propyl alcohol, butanols.
Reagent B-sulfuric acid, hydrochloric acid, nitric acid and water-soluble salt thereof; Their water-soluble salt is meant sodium sulfate, sulfate of ammoniac, copper sulfate, ferric sulfate, Tai-Ace S 150, sal epsom, manganous sulfate, Lithium Sulphate, zinc sulfate, sodium-chlor, Repone K, cupric chloride, iron trichloride, ferrous chloride, magnesium chloride, calcium chloride, aluminum chloride, bariumchloride, Manganous chloride tetrahydrate, ammonium chloride, ammonium nitrate, cupric nitrate, zinc nitrate, SODIUMNITRATE, reagent B can also be Sulfothiorine, Neutral ammonium fluoride, Potassium monofluoride, brometo de amonio, Potassium Bromide, barium bromide, lithiumbromide, magnesium bromide, ammonium iodide, barium iodide, calcium iodide, potassiumiodide, zinc iodide.
The invention has the advantages that: denitrification residue can be separated into acidizer and two kinds of components of nitride, non-pollution discharge after the industrial application; Acidizer is all reusable with the moisture, the reagent that steam, has not only thoroughly eliminated the pollution of residue to environment, and can reduce the denitrification process cost significantly.
Know-why of the present invention has been to use a kind of reagent A and another kind of reagent B and denitrification residue to merge, give nitride in the denitrification residue floats on solution with the performance of emulsion resistance in the aqueous solution surface, acidizer and reagent B then are dissolved in the aqueous solution that contains reagent C.From two kinds of parting liquids, steam moisture and reagent A and reagent C respectively after adopting skimmer that it is separated, just can obtain containing acidizer and the nitride of reagent B.
Embodiment 1:
With subtracting two fraction denitrification residues and reagent A-toluene, reagent B-sodium sulfate, according to denitrification residue: toluene: the part by weight of sodium sulfate=100: 40: 2, under 90 ℃ temperature condition, merge through stirring, obtain the denitrification residue fusions.Then according to the denitrification residue fusions: the part by weight of water capacity liquid=100 that contain reagent C: 00-300 add weight concentration be 30% contain the reagent C alcoholic acid aqueous solution, under 75 ℃-85 ℃ through stirring, sedimentation, separation, from two kinds of parting liquids, steam moisture content reagent A and reagent C respectively again, just can obtain nitride and acidizer.
Embodiment 2: subtract three parts of denitrification residues and reagent A toluene, denitrification residue by weight: the ratio of reagent A=100: 40, under 75 ℃ of-85 ℃ of temperature condition, merge through stirring, add in per then 100 parts denitrification residue fusions and contain 300 parts of the reagent C alcoholic acid aqueous solution, the weight concentration of aqueous ethanolic solution is 30%, under 80 ℃ of temperature condition,, from two kinds of parting liquids, steam moisture content and reagent A and reagent C more respectively, just can obtain acidizer and nitride through stirring, sedimentation, separation.
The nitride condensation point of separating is lower, is rich in condensed-nuclei aromatics and colloid, is that part is set up in the ideal adjustment of producing road bitumen jointly.The acidizer of separating reaches 90% through experiment dealkalize nitrogen rate.
