Abstract
The present invention relates to a heavy oil vanadium-inhibiting agent for gas turbines or electric power plant boilers, which is an aqueous solution of magnesium acetate. Because the vanadium-inhibiting agent has high magnesium content, the vanadium-inhibiting agent is easy not to crystallize, and compounds produced by the inhibiting agent and vanadium has little smutch and are loose and are easy to remove. The water-soluble vanadium-inhibiting agent is low in cost and simple in production, and therefore, the present invention is an ideal heavy oil vanadium-inhibiting agent for gas turbines or electric power plant boilers.
Description
The present invention is a kind of heavy oil vanadium inhibitor that is used for internal combustion turbine or boiler of power plant, and this heavy oil vanadium inhibitor is the magnesium acetate aqueous solution, uses it can suppress the vanadium corrosion of fuel heavy oil in internal combustion turbine or the boiler of power plant.
Contain trace vanadium in the fuel heavy oil, it has serious corrosive nature to the engine alloy, is uneconomic and want to remove vanadium from fuel heavy oil, so need suppress its infection with the method for chemistry.Existing vanadium-inhibition agent is divided into oil soluble and water-soluble two kinds.The oil soluble vanadium-inhibition agent costs an arm and a leg, and then cheaply how water soluble vanadium-inhibiting agent.
Water soluble vanadium-inhibiting agent generally adopts sal epsom (MgSO
47H
2O), its weak point is: (1). with sal epsom (MgSO
47H
2O) vanadium-inhibition agent of making, the content of magnesium generally has only 3%; (2) sal epsom (MgSO
47H
2O) solubility with temperature alters a great deal, and the Adlerika of 3% Mg content still can crystallization when low temperature, the normal operation of overslaugh vanadium-inhibition agent; (3) .SO
4 -2The existence of root can reduce magnesium oxide and suppress vanadium corrosive ability; (4). sulfate concentration height in the black dirt, black dirt is just harder, is difficult for removing.
The objective of the invention is to provide a kind of heavy oil vanadium inhibitor that is used for internal combustion turbine or boiler of power plant, by replacing magnesium sulfate solution as vanadium-inhibition agent, to reach the vanadium corrosive nature that suppresses internal combustion turbine or boiler of power plant with the magnesium acetate aqueous solution.
The object of the present invention is achieved like this: a kind of heavy oil vanadium inhibitor that is used for internal combustion turbine or boiler of power plant, it is characterized in that this vanadium-inhibition agent is the aqueous solution of magnesium acetate, and its standard is: (by weight)
1). the content of magnesium is 5.4%-8% in the magnesium acetate aqueous solution;
2).(Na+K)/Mg＜1/4000；
3).Ca/Mg ＜1/2000；
4).Pb/Mg ＜1/5000；
5).V/Mg ＜1/5000；
6). throw out＜0.25%;
The concentration of the magnesium acetate aqueous solution is that the content with magnesium calculates, and its concentration is 5.4%-8%, and the pH value of solution is between 6.5-7.0.
The technology that the present invention produces the magnesium acetate aqueous solution is to be raw material with magnesium oxide or magnesiumcarbonate or magnesium hydroxide, after the water damping, with acetic acid reaction, add acetic acid during reaction while stirring, after treating that magnesium compound dissolves fully, the pH value with the ammoniacal liquor adjusting aqueous solution makes it between 6.5--7.0.
The present invention adopts the magnesium acetate aqueous solution as vanadium-inhibition agent, and its advantage is: (1). and Mg content height, Mg content are that the magnesium acetate aqueous solution of 5.4%-8% is difficult for crystallization; (2). the negatively charged ion of magnesium acetate is a hydrocarbon polymer, thereby black dirt is few, loose easily remove.
Heavy oil vanadium inhibitor action principle of the present invention is: contain vanadium in the heavy oil, produced Vanadium Pentoxide in FLAKES after the burning, its fusing point is 650 ℃ only, is molten state, has corroded gas turbine blades thereby pollute.Add magnesium acetate in heavy oil after, through high temperature sintering, generate magnesium oxide, magnesium oxide and Vanadium Pentoxide in FLAKES effect generate vanadic acid magnesium (Mg
3V
2O
8), its fusing point so just can not pollute the corrosion gas turbine blades up to 1124 ℃.Reaction equation is:
The magnesium acetate aqueous solution that the present invention produced, the consumption of its water is to decide with the concentration of producing magnesium acetate, and the concentration of magnesium acetate is decided with the content of vanadium in the heavy oil, the content of vanadium height, the magnesium acetate concentration that is acted on will be big, the consumption of water will correspondingly reduce, and the magnesium acetate of general various concentration is all by using the concentration that need be diluted to requirement.
The concentration range of the used acetic acid of the present invention is 30%--100%, and the consumption of acetic acid is as the criterion to react completely with magnesium compound.
Temperature of reaction of the present invention is to determine with the magnesium compound that uses, and as magnesium oxide or magnesium hydroxide, reaction is generally carried out at normal temperatures, and when using magnesiumcarbonate, will heated and boiled during reaction.
Embodiment:
1. with magnesium oxide production concentration 6% the magnesium acetate aqueous solution.After getting 40 gram magnesium oxide and adding 110 gram water-wets, add entry while stirring: acetic acid 220 grams of Glacial acetic acid=1: 1, the back that reacts completely at normal temperatures (dissolving is the back fully), being adjusted to PH with ammoniacal liquor is 6.5--7.0.
2. with magnesiumcarbonate production concentration 8% the magnesium acetate aqueous solution.Get 30 the gram magnesiumcarbonate add 40 the gram water-wets after, add while stirring 40 the gram Glacial acetic acid, heated and boiled to solution transparent after, being adjusted to PH with ammoniacal liquor is 6.5--7.0.
3. with magnesium hydroxide production concentration 5.4% the magnesium acetate aqueous solution.Get 150 gram magnesium chloride (MgCl
26H
2O), add 500 ml waters dissolvings after, under agitation slowly add 170 milliliters of 40% sodium hydroxide solutions, add 800 milliliters of distilled water again, washing precipitation, Mg (OH)
2Washing of precipitate is to Na
+Meet the requirements, placement is spent the night, and inclines to supernatant liquid, and drying is 24 hours under 98 ℃, gets the stock white mashed prod.Get this thing 50 grams, add Glacial acetic acid 22 gram dissolvings at normal temperatures after, being adjusted to PH with ammoniacal liquor is 6.5--7.0.
4. directly use water as solvent with commercial magnesium acetate dissolving, water consumption is decided according to needed magnesium acetate concentration.
