Abstract
An oil-dispersing vanadium depressant is prepared from the nano-class alkaline carbonate modified by alkyl sulfate and the organic solvent. Its advantages are high dispersity and stability, and high application effect.
Description
Technical field
The present invention relates to oily dispersive vanadium-inhibition agent and form and preparation method thereof, this vanadium-inhibition agent be a kind of can be in oil dispersive magnesium basic carbonate dispersion in organic solvent, it can effectively suppress the corrosion that contained vanadium causes in the combusting heavy oil in internal combustion turbine or the boiler of power plant.Relating in particular to a kind of oily dispersive vanadium-inhibition agent forms and preparation method thereof.
Background technology
Existing vanadium-inhibition agent is divided into oil soluble (CN1278550A) and water-soluble (CN1055110C) two kinds.Wherein the water-bath dispersion agent is difficult for mixing mutually with heavy oil because of it, need independent fog system in use, thereby use inconvenience, and effect is also poor because of incomplete mixing.Oil-soluble dispersant is generally magnesium oxide, magnesium hydroxide because of employed magnesium compound, thereby easily absorbs airborne water, carbonic acid gas and produce gelling and surface skining phenomenon.Though there is patent (CN1278550A) can add catalyzer when being reported in neutralization reaction improving above-mentioned phenomenon, this technology catalyst system therefor price height, thus production cost is improved.The objective of the invention is to provide a kind of oily dispersive basic carbonate magnesium vanadium inhibitor simple and easy to do, with low cost and form and preparation method thereof, utilize reaction to produce that nanometer particle is easy to disperse, free settling and magnesium basic carbonate are not prepared vanadium-inhibition agent product easy to use, effective, shelf-stable to steam, the insensitive characteristics of Carbon Dioxide in Air in organic solvent.
Summary of the invention
The purpose of this invention is to provide a kind of oily dispersive vanadium-inhibition agent forms and preparation method thereof.
Magnesium basic carbonate (the molecular formula 3MgCO that the composition of oil dispersive vanadium-inhibition agent is is 50～300 nanometers by 10～50 parts of median sizes through the alkyl-sulphate surface modification
3Mg (OH)
23H
2O) form with 90～50 parts of organic solvents.
Oil dispersive vanadium-inhibition agent is formed the preparation method 5～30 parts of alkyl-sulphates is dissolved in 200 parts of water, be warming up to 50～80 ℃, stir fast and drip the magnesium salt solution of 100 parts of magnesium contents 5～10% and 100～300 part 5～10% bicarbonate aqueous solution down simultaneously, drip to finish with 5～10% ammonia solns and transfer PH to 8～9, promptly getting median size is the surface modification magnesium basic carbonate dispersion liquid of 50～300 nanometers; Organic solution is added in the above-mentioned reaction dispersion liquid, the surface modification magnesium basic carbonate in the extraction and dispersion liquid, layering, the oil reservoir deionized water wash, vacuum removal moisture and excessive solvent get final product
Embodiment
Oil dispersive vanadium-inhibition agent is the preparation method be dissolved in 5～30 parts of alkyl-sulphates in 200 parts of water, be warming up to 50～80 ℃, stir fast and drip the magnesium salt solution of 100 parts of magnesium contents 5～10% and 100～300 part 5～10% bicarbonate solution down simultaneously, utilize the dissemination of alkyl-sulphate in water to form the particle of median size 50～300 nanometers, drip and finish, transfer pH value to 8～9 with 5～10% ammoniacal liquor, promptly getting median size is the surface modification alkaline magnesium carbonate dispersion liquid of 50～300 nanometers.Magnesium basic carbonate in this dispersion liquid has become lipophilicity because of the adsorption layer that its surface has formed alkylsurfuric acid magnesium, thereby can extract with organic solvent easily.By the magnesium content requirement, add an amount of organic solvent extraction, layering, the oil reservoir deionized water wash, decompression removes trace water and the excessive solvent in the oil reservoir down then, gets final product.
Abovementioned alkyl vitriol is meant a kind of or any two kinds mixture in sodium lauryl sulphate, dodecyl sulphate potassium, ammonium lauryl sulfate, Trombovar, tetradecyl vitriolate of tartar, ammonium tetradecyl sulfate, Sodium palmityl sulfate, hexadecyl hydrosulfate potassium, the hexadecyl hydrosulfate ammonium.
Magnesium salts is meant a kind of or any two kinds mixture in magnesium chloride, sal epsom, magnesium nitrate, magnesium acetate, the magnesium formiate.
Supercarbonate is meant a kind of or any two kinds mixture in sodium bicarbonate, bicarbonate of ammonia, the saleratus.
Organic solvent is meant kerosene, diesel oil, heavy oil, toluene, dimethylbenzene, C
9Aromatic hydrocarbons, C
10A kind of or any two kinds mixture in the above aromatic hydrocarbons.
Embodiment 1
Add entry 200g in the four-hole boiling flask that the 1000ml band stirs, Sodium palmityl sulfate 10g stirs and is warming up to 70 ℃, makes the Sodium palmityl sulfate dissolving.Add magnesium sulfate solution 100g and the 5% sodium bicarbonate aqueous solution 270g that contains magnesium 5% respectively in two dropping funnels, drip above-mentioned two kinds of solution under the high-speed stirring simultaneously, the dropping time was controlled at about 1 hour, and temperature is controlled at about 70 ℃ during dropping.Drip and finish, with 5% ammoniacal liquor accent pH value to 8～9 (needing 70g approximately), continue to stir half an hour again, add diesel oil 21g and dimethylbenzene 50g extraction then, oil reservoir washs repeatedly with deionized water 100ml, till sodium ions content is less than 200ppm.Oil reservoir heats under-0.09Mpa vacuum, removes contained micro-moisture and dimethylbenzene, can get the about 50g of vanadium-inhibition agent product, magnesium content 10%.Magnesium in this product exists with the magnesium basic carbonate form, and median size 210 nanometers, outward appearance are translucent oily dispersion, stores and does not produce precipitation in 3 months, is exposed to not gelling in the air, skinning not.Product by this explained hereafter is thin owing to particle diameter, good dispersity, thereby be easy to mix with heavy oil, it is effective to suppress the vanadium corrosive.
