Abstract
The invention discloses oil dispersant for quickly removing floating oil on a water surface. The oil dispersant is characterized by comprising the following components in percentage by weight: 0.5 to 30 percent of nonionic surfactant, 0.1 to 10 percent of dimerization glyceride, 0.1 to 10 percent of alkyl polyglucoside, 0.1 to 10 percent of anionic surfactant with the pH value of between 6.5 and 7.0, 0.5 to 15 percent of oxygen-containing solvent, 0.5 to 10 percent of ethanol, 1 to 5 percent of hydrocarbon solvent and 50 to 80 percent of water with the pH value of between 6.5 and 7. The using amount (21 percent to the maximum) of the solvent is reduced. Compared with the prior art, the oil dispersant can quickly remove floating oil on the water surface on the premise of using the same dosage of oil dispersant; moreover, a small amount of oil enters water, so that natural degradation pressure is lowered; simultaneously, the oil dispersant has the advantages of low cost and low secondary pollution.
Description
Technical field:
The present invention relates to a kind of micro-emulsion type oil spill dispersant, especially a kind of cost is low, biological degradation is fast, can reduce secondary pollution and can eliminate the oil spill dispersant and the preparation method of oil slick fast.
Background technology:
The various oil product cuts of oil and extraction thereof are the present most important energy, but all unavoidably have the problem of crude oil and various oil leaks in exploitation, refining and each link of using, as leakage, the oil tanker of marine oil well leak, the leakage of waters periphery oil depot or the like.When the oil leak accident takes place when, source of leaks need be blocked shutoff on the one hand, need oil product is reclaimed as far as possible (in any case because of final effort, still having quite a few oil product can't reclaim) on the other hand.Retain for a long time at the water surface if let alone oil product, then can make oxygen can't enter water body water surface sealing, influence hydrobiological normal growth in addition because of anoxic dead; Particularly crude oil leakage also can have influence on close birds.Therefore for irretrievable leakage oil product, just need to use oil spill dispersant that it is scattered in the water as early as possible, avoid hiding the water surface, microorganism reduces the pollution and the ecological damage of oil product to water environment to the decomposition of oil product in the quickening water.The solvent that adopts in the oil spill dispersant in the past is higher, can reach more than 50% of oil spill dispersant total mass, can bring solvent based oil products a large amount of in the water again in the oil that disappears, cost height not only, and environment caused secondary pollution.
Summary of the invention:
The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, provides that a kind of cost is low, biological degradation fast, can reduce the oil spill dispersant and the preparation method that can eliminate oil slick fast of secondary pollution.
Technical solution of the present invention is: a kind of oil spill dispersant of quick elimination oil slick is characterized in that contained raw material and weight percent are as follows: nonionogenic tenside 0.5～30%; Two polyglycerol esters 0.1～10%; Alkyl glycoside 0.1～10%; The pH value is 6.5～7.0 anion surfactant 0.1～10%; Oxo solvent 0.5～15%; Ethanol 0.5～10%; Hydrocarbon solvent 1～5%; Water 50～80%; The pH value is 6.5～7.0.
Described nonionogenic tenside is the mixture of fatty alcohol-polyoxyethylene ether (9), fatty alcohol-polyoxyethylene ether (6) and fatty alcohol-polyoxyethylene ether (3), and mass ratio is successively: 10～13: 4～5: 1～2.
Described anion surfactant is fatty alcohol-polyoxyethylene ether (9) carboxylic acid sodium, Sodium dodecylbenzene sulfonate, sodium lauryl sulphate or dodecyl alcohol polyoxyethylene ether (3) sodium sulfate.
Described oxo solvent is at least a in ethylene glycol phenyl ether, butyl glycol ether, ethylene glycol ethyl ether, Diethylene Glycol butyl ether, the diethylene glycol ether.
Described hydrocarbon solvent is that flash-point is 60～70 ℃ a petroleum solvent.
A kind of preparation method of oil spill dispersant of above-mentioned quick elimination oil slick is characterized in that carrying out as follows successively:
A. all raw materials outside will dewatering mix and stir;
B. the water that at every turn adds water inventory 5% adds the water of water inventory 5% again after stirring, proceed to the water that adds water inventory 50% successively repeatedly, and remainder water is once added, and stirs then, can obtain transparent micro emulsion.
The present invention has adopted the mutual compatibility effect of plurality of raw materials, especially solvent adopts double solvents (oxo solvent, ethanol and hydrocarbon solvent) and compound surfactant, reduced the usage quantity (the highest by 21%) of solvent, compared with prior art, under the prerequisite of using the Isodose oil spill dispersant, can eliminate oil slick fast, and the oil product that enters in the water is less, reduce the pressure of natural degradation, had the advantage that cost is low, secondary pollution is little simultaneously.
Embodiment:
Embodiment:
The mass percent of raw material and each raw material is as follows:
Nonionogenic tenside 0.5～30%; Two polyglycerol esters 0.1～10%; Alkyl glycoside 0.1～10%; The pH value is 6.5～7.0 anion surfactant 0.1～10% (in butt); Oxo solvent 0.5～15%; Ethanol 0.5～10%; Hydrocarbon solvent 1～5%; Water 50～80%; It is 6.5～7.0 that each raw material mixes back pH value.
The preparation method carries out successively as follows:
A. all raw materials outside will dewatering mix and stir;
B. the water that at every turn adds water inventory 5% adds the water of water inventory 5% again after stirring, proceed to the water that adds water inventory 50% successively repeatedly, and remainder water is once added, and stirs then.
Nonionogenic tenside can be the mixture of fatty alcohol-polyoxyethylene ether (9), fatty alcohol-polyoxyethylene ether (6) and fatty alcohol-polyoxyethylene ether (3), and the mass ratio of fatty alcohol-polyoxyethylene ether (9), fatty alcohol-polyoxyethylene ether (6) and fatty alcohol-polyoxyethylene ether (3) is 10～13: 4～5: 1～2.
PH value is that 6.5～7.0 anion surfactant is with sodium hydroxide or potassium hydroxide allotment fatty alcohol-polyoxyethylene ether (9) carboxylic acid sodium, Sodium dodecylbenzene sulfonate, sodium lauryl sulphate or dodecyl alcohol polyoxyethylene ether (3) sodium sulfate.
Oxo solvent is at least a in ethylene glycol phenyl ether, butyl glycol ether, ethylene glycol ethyl ether, Diethylene Glycol butyl ether, the diethylene glycol ether.
Hydrocarbon solvent is that flash-point is 60～70 ℃ a petroleum solvent.
The embodiment of the invention is applied to oil slick, can fast oil slick be eliminated, compared with prior art (use same dose), decomposition rate can improve about 20%.After testing, disperse the oil slick of same weight, the organism (comprising tensio-active agent and solvent) that adds in the entry reduces 50% than prior art, thereby has reduced the pressure of natural degradation, more helps the fast quick-recovery of environment.
