Abstract
The present invention belongs to a processing method of a 'waste oil' class. In a use process, various fluid oil can be gradually polluted and deteriorated, and can not be used continuativelly. Thus, people exigently need a fluid oil regeneration technology which has the advantages of high efficiency, low cost and no pollution. Grease type polyamide resin having an annular structure is added into ' waste oil ', which enables a large amount of suspended matters in the 'waste oil' to be effectively removed to achieve the purpose of 'waste oil ' regeneration, wherein the grease type polyamide resin is formed by reacting the dimer of unsaturated fatty acid of eighteen carbon atoms and aliphatic polyamine.
Description
The invention belongs to the treatment process of " waste oil " class.
Various lubricating oil in use, contamination and deterioration gradually all, and can not continue to use is called " waste oil " traditionally.Reduce day by day in the thick oil resource, the needs of The modern industry traffic and lubrication engineering development, and people are to high-level efficiency under the situation of requirement on environmental protection increasingly stringent, lubricating oil regeneration process is subject to people's attention day by day cheaply.
" waste oil " reclaiming process that extensively adopts is sulfuric acid/carclazyte method at present.This kind technology except that severe corrosion equipment, produces a large amount of reluctant acid sludges owing to use a large amount of sulfuric acid, no matter adopts the way of burning or burying, and all can cause environmental pollution.Proof other treatment process comprises neutralisation, burns in the cement kiln incinerator etc., because a variety of causes does not have a kind of gratifying treatment process so far.
In order to reduce the consumption of sulfuric acid and carclazyte, though can utilize some inorganic flocculating agent, as Tai-Ace S 150, water glass etc. " waste oil " is carried out pre-treatment, but still the processing that can not solve waste residue, waste water effectively on the spot, or production cost is improved, the operation unsafe factor increases, and the quality of reclaimed instability greatly reduces " waste oil " regenerated economic benefit.
For fear of using sulfuric acid, adopt distillation/carclazyte method, solvent extration or distillation/hydrofinishing method, its shortcoming is that treatment temp is too high, or faces upward with solvent ratios too greatly, or recovery plant's construction investment is very big.
The invention provides a kind of can carry out effectively " waste oil " and regenerate, and overcome the in-problem method of above-mentioned all methods.
The inventor is carrying out on the basis of various researchs " waste oil " renovation process, screening by experiment, find a kind of specific organic floculant, it can make a large amount of suspended substances in " waste oil " remove effectively, and the moisture in the emulsion separated, can make the work in-process of regeneration base oil by one step of organic-flocculation operation, then through distillation and adsorption filtration, or centrifugation, can obtain corresponding base oil, its physicochemical property and new base oil basically identical can reuse fully.That is to say that feature of the present invention is that the oil-based polyamide resins with ring texture is added to " waste oil " lining.This resinoid is to be formed by the dimer of vegetable fatty acids and aliphatic polyamine reaction.Vegetable fatty acids can be the unsaturated fatty acids of 18 carbon atoms such as linolic acid, behenic acid or eleostearic acid, and aliphatic polyamine can be quadrol, Diethylenetriaminee (DETA) or triethylenetetramine.
The polymkeric substance that the dimer of different lipid acid and aliphatic polyamine generate, its representative structure can be expressed as:
(1) eleostearic acid dimer and Diethylenetriaminee (DETA).
(2) eleostearic acid dimer and triethylenetetramine.
(3) linoleic acid dimer and Diethylenetriaminee (DETA).
(4) linoleic acid dimer and triethylenetetramine.
(5) linoleic acid dimer and quadrol.
R can be hydrogen atom or corresponding lipid acid dimer in the formula.
Their molecular weight is at 500～9000.Because vegetable fatty acids is different with the aliphatic polyamine raw material type, resulting resin has very big difference in nature, and the listed several representatives of table 1 all can be used as " waste oil " regenerated organic floculant, even with they any fusion, still have effect same.
Listed 1～No. 5 organic floculant of table 1 all has good oil soluble, and volatility is little.This type of flocculation agent is characterised in that to have cyclic molecular structure and certain molecular weight.Owing to contain alkyl and unsaturated double-bond and various polar group in the molecule, as primary amine, secondary amine and amide group, normal temperature down can with the peroxidation in " waste oil ", make the additive passivation that remains in the oil, make the suspended impurity in the oil, comprise emulsive moisture, assemble automatically and sedimentation.
The consumption of organic floculant is 0.1～5% of " waste oil " weight.In some cases, when containing more lighting end in " waste oil " (open flash point is lower than 165 ℃, and close flash point is lower than 145 ℃), also can use bigger amount, but this is uneconomic.
For flocculation agent is evenly dispersed in the oil, and quicken the settling velocity of suspended impurity and moisture, preferably earlier flocculation agent is dissolved with organic solvent (toluene, dimethylbenzene), and suitably heat, adopt the method for centrifugation simultaneously, impurity is removed from " waste oil ".
Suspended impurity in " waste oil " is through organic floculant precipitation and after separating, and oil phase can make the base oil of recovered oil through underpressure distillation and carclazyte adsorption filtration, its rate of recovery be " waste oil " 85～90%.Replenish the additive of loss, promptly can be made into processed oil.And with traditional sulfuric acid/clay regeneration art breading " waste oil " of the same race, the rate of recovery of gained base oil only is 79%, and still unspent additive but all destroys in " waste oil ".
" waste oil " of the present invention renovation process, " waste oil " regeneration applicable to common mechanical oil, the coating that contains various resins (as Synolac, polyvinyl chloride (PVC) RESINS, Resins, epoxy) and cleaning printing-ink is all effective, especially for beeliner, boats and ships and the applied diesel engine oil of stationary power generation machine, better effects if.Diesel engine oil is the lubricating oil that is used for the compression ignition internal combustion engine.In recent years, because the power of engine constantly increases and the prolongation of oil draining period, in oil, be added with more additive, as anti-oxidant anti-corrosion additive zinc dialkyl dithiophosphate, peace and quiet dispersing additive sulfur phosphorization polyisobutylene titanate salt etc., its objective is that soot, colloid, rotten additive and abrasive metal that oil is in use formed form suspended substance.The existence of these suspended substances has increased the difficulty of lubricant oil regeneration greatly.And employing present method then can be removed impurity at an easy rate, reaches the regenerated purpose.
In general, use when of the present invention, the viscosity of " waste oil " is big more, and the flocculating effect of impurity is obvious more.For full-bodied " waste oil ", with preferably warp " sedimentation of heating " pre-treatment earlier before this method regeneration, purpose is to remove mechanical impurity and the free water content that deoils.Used container and heating mode are identical with traditional sulfuric acid/carclazyte technology.
Greater than 1% waste oil, also can directly use flocculation agent for water content.And big like this water content is unallowed with vitriolization directly.
As mentioned above, the present invention compares with traditional sulfuric acid/carclazyte method, and its advantage is: (1) has thoroughly eliminated the problem of environmental pollution that causes because of the generation acid sludge, and can obtain new product; (2) can utilize the equipment of original sulfuric acid/clay regeneration technology; (3) rate of recovery height, simple and easy, the safety of operation; (4) " waste oil " regenerated social benefit and economic benefit have been improved greatly.
The patent report of at present existing a lot of organic floculants has used N-phenyldiethanol-amine, United States Patent (USP) 3305478 to use Diethylenetriaminee (DETA) as United States Patent (USP) 2568583 ...Immediate with the present invention is the polyamide-based resin that Japan special permission communique 51-42000 is adopted, but its constitutional features is indicated as being straight chain shape oligopolymer.Be resins such as polymeric amide polyamines, polyacrylamide or polycaprolactam, but this resin dispersion degree is big, and the gained dregs of fat contain macromolecular fibre, be suitable for as the bituminous supplement.And flocculation agent dispersity used in the present invention is little, be easy to control and grasp in the production, and the gained dregs of fat are neutral, contain a large amount of soft carbons, lubricating oil and resinous principle, except that the starting material that can be used as electric carbon product, itself promptly be the work in-process of printing-ink, can be processed into ink product on the spot.So the technology that this is new both can be protected environment, can improve society and economic benefit again, be a kind of to industry and the extremely beneficial method of environment.
