Abstract
The present invention relates to an inhibitor for preventing liquid hydrocarbon from evaporating and a preparation method thereof, which comprises the following components proportioned by weight 2.5 to 30 percent of hydrocarbon surfactant, 10 to 30 percent of fluoric surfactant, 1 to 8 percent of spreading agent, 1 to 10 percent of filmogen, 0.1 to 10 percent of stabilizing agent, 1 to 30 percent of antifreezing agent, and water for the rest. The present invention can effectively inhibit liquid hydrocarbon from naturally and greatly evaporating, and prevent fire accident.
Description
Technical field
The present invention relates to a kind of liquid hydrocarbon evaporable inhibitor and preparation method thereof, specifically a kind of liquid hydrocarbon evaporation inhibitor and preparation method thereof of preventing.
Background technology
Along with the development of human society progress, the use and the demand of liquid towards hydrocarbon constantly increase, but liquid hydrocarbon unavoidably can evaporate in production, transportation, storage and use in large quantities, this has not only wasted ample resources, polluted environment simultaneously, even more serious is that some liquid hydrocarbon (particularly fuel oils) is because its evaporation in a large number naturally, run into static or the burning things which may cause a fire disaster fire that leads on fire that just can burn, make people's lives and properties be subjected to serious threat.In order to suppress the evaporation of liquid hydrocarbon, the units concerned of the many developed countries in the world and China all at the inhibitor of development liquid hydrocarbon evaporation, up at present, still find no gratifying result.N-1 type (liquid hydrocarbon) inhibitor that China succeeded in developing in calendar year 2001, be the inhibitor that a kind of half condensed film and liquid unimolecular film combine, it can suppress the part evaporation of flammable liquid hydrocarbon, but because its density is bigger, have only water-soluble and do not have an oil soluble, limited in therefore using.The China's oil chemical enterprise is many because of the security incident that the liquid hydrocarbon leakage produces in process of production every year, and the loss of causing for the country and people's lives and properties is very huge.Therefore develop a kind of applied range, existing water-soluble, there is oil-soluble evaporation inhibitor to be highly profitable again.
Summary of the invention
The objective of the invention is the defective at currently available products, a kind of liquid hydrocarbon evaporation inhibitor is provided, it can effectively suppress liquid hydrocarbon evaporation in a large number naturally, prevents the generation of fire failure.
Another object of the present invention provides the preparation method of this liquid hydrocarbon evaporation inhibitor.
Technical scheme of the present invention is achieved in that it is made up of following component by weight ratio:
Hc-surfactant 2.5～30%, fluorine surfactant 10～30%,
Spreading agent 1～8%, membrane-forming agent 1～10%, stablizer 0.1～10%,
Antifreezing agent 1～30%, surplus are water.
Described hc-surfactant is one or more in sodium lauryl sulphate, alkyl-glucoside, polyoxyethylene fat sodium sulfate, Bs-12, QF, 6501, CPS, LS, JFC, alkyl brometo de amonio, organosilicon or the alkylol amide; Described fluorine surfactant is one or more in ammonium perfluorocaprylate, perfluorocarboxylic acid sodium, perfluoro alkyl sulfonic acid potassium, FC-1203, FC-4, FC-10, FC-3B, FC-2, OBS, FN-3, FN-2, DF-134, fluorine-containing trimethyl-glycine, fluorine carbon phosphoric acid ester, the perfluoro propylene acid; Described spreading agent is C
4～C
18One or both of alkyl alcohol or fluorochemical surfactant; Membrane-forming agent is a polyvinyl alcohol, polyoxyethylene, polyethylene oxide, one or more in the pyrrolidone; Stablizer is K
12, ferrocene, salt, sodium polyphosphate, fructose, polysaccharide, make a gift of in sugar or the both sexes fluorine surfactant one or more; Antifreezing agent is one or more of ethanol, ethylene glycol, Diethylene Glycol butyl ether, diethylene glycol ether, carboxamide, ammonium polyphosphate.
Antifreezing agent mainly is in order to reduce the congealing point of inhibitor.It can be used at a lower temperature.The stable of film is the key of inhibitor, we select molecular chain length, bulky macromolecular compound as stablizer, as fructose, polysaccharide, make a gift of sugar or both sexes fluorine surfactant, after being dissolved in water, it forms colloidal solution with certain viscosity, be scattered in the molecule in the solution owing to have hydrophilic radical and hydrophobic grouping simultaneously, show stronger surfactivity, have the effect that reduces surface tension and interfacial tension.When evaporation inhibitor is in liquid hydrocarbon; its molecular adsorption is to the interface; reduce interfacial tension; promote the formation at interface; part chain owing to it extends on the interface simultaneously; and, formed a two-dimentional protecting network by chain interphase interaction (comprising intramolecularly and intermolecular power), interfacial film is strengthened.Because it has surfactivity,, strengthen repair so can accelerate rate of adsorption.Bringing certain difficulty owing to there is in the water the high colloid of viscosity to give to sprawl, is the spreading rate that strengthens the aqueous solution, and we have selected and can help fluorine-containing surfactants that the aqueous solution faster sprawls as spreading agent, have improved the spreading rate of the aqueous solution greatly.
Membrane-forming agent is the core of inhibitor, and we know, suppress the hydro carbons evaporation, and its prerequisite can have in steady and continuous of hydro carbons surface formation, and the rete of certain intensity is arranged.Reach this purpose, film forming material must be non-oleaginous.We select the alcohols of medium carbochain as membrane-forming agent, because fluorocarbon surfactant has the excellent properties that three Senior Two are hated, it can reduce to surface tension extremely low, hc-surfactant is again that to reduce interfacial tension fabulous: all reduce to when extremely low when surface tension and interfacial tension, it sprawls film forming speed will be very fast.Moreover the alcohols of low carbon chain easily forms film spreading, the film that the alcohols of high carbon chain forms, rigidity is too strong, film easily breaks and is difficult for repairing, so in adopting the alcohol of carbochain as membrane-forming agent, so this inhibition film is to work in coordination with integral part by above number of substances.Because the surface tension of this inhibition film is lower than the surface tension of liquid hydrocarbon, so can launch at liquid level.
We select fluorine surfactant and hc-surfactant composite is in order to bring into play the synergistic effect between the two.
Preparation method of the present invention is as follows:
At first fluorine surfactant, hc-surfactant are added water and mix, add membrane-forming agent, spreading agent, stablizer and antifreezing agent then and mix, get product after stirring.
Other method of the present invention is as follows: it is made up of following component by weight ratio:
Hc-surfactant 2.5～30%, fluorine surfactant 10～30%,
Spreading agent 1～8%, membrane-forming agent 1～10%, stablizer 0.1～10%,
Antifreezing agent 1～30%, surplus are gasoline.
Described spreading agent is C

The preparation method is identical with last invention, just changes solvent into gasoline.By above-mentioned two kinds of methods, can prepare water-soluble and two kinds of evaporation inhibitors of oil soluble, its range of application is very extensive.
Beneficial effect:
1, effectively reduces the saturation vapour pressure that is suppressed hydro carbons.
Make an addition to the blank contrast of its saturation vapour pressure 56kpa 65kpa in the M60 methanol gasoline
After making an addition to crude oil, the blank contrast of its saturation vapour pressure: 34.5kpa is: 38.2dpa
2, the vaporization losses that effectively suppresses hydrocarbon products
Make an addition in the 90# gasoline 30 ℃ one hour, suppressing efficient is 43%
3, effectively suppress to improve the flash-point of product
Suppressing flash-point for 90# gasoline is: 49.5 ℃
Crude oil is suppressed flash-point is: 55 ℃, blank contrast is 22 ℃
4, improve the dynamic performance of fuel oil for vehicles and the discharging of reduction poisonous and harmful tail gas.
Added AM-05 suppressed after 90# gasoline, fuel engines is not had influence, but fuel-economizing more than 5%, exhaust emissions reduces about 40%.
