Abstract
A process for extracting acidifying agent and nitride from residual dregs after denitrifying the basic oil of lubricant includes mixing the residual dregs with reagent A (asolvent of chloride) and B (deemulsifier), adding the aqueous solution of regent C, stirring, settling, separating liquid A from B, distilling liquid A to obtain reagent A and in turn nitride, and distilling liquid B to obtain water and reagent C and in turn the acidifying agent containing reagent B.
Description
The present invention relates to the petroleum refining field, more particularly, provide a kind of treatment process denitrification residue.
CN94115100.5 provides a kind of highly effective sulfur-preserving and denitrifying technology of lubricant base oil that is used to produce, and the denitrification residue that it produces in process of production is difficult for handling.CN94149100.5 provides a kind of method of handling denitrification residue with neutralisation, its weak point is to handle denitrification residue with this method, and acidizer has become salt through neutralization, and acidizer can not be extracted, the brackish water liquid that is produced will discharge, and can produce environment to pollute.
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 part by weight of the aqueous solution that contains reagent C: 100: 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, and the weight concentration in the aqueous solution is 2-50%;
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 can be 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, and as Na

2Reagent C can be any one in the following material: methyl alcohol, ethanol, ethylene glycol, propyl alcohol, butanols.
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.
