The preparation method of the high-concentration vanadium inhibitor provided by the invention is simple in process; and the obtained vanadium inhibitor has the advantages of high efficacy, high concentration, easy mixing, good fluidity, no adhesion to container wall and good stability, thus can be stored for a long time, is difficult to agglomerate and crust when encountering with water or air, is convenient to be stored, is mainly adaptable to a heavy oil fired boiler, and can effectively inhibit the corrosion caused by S, V, Na and other harmful components in the heavy oil.
Description
Technical field
The present invention relates to a kind of additive for heavy oil, particularly, relate to a kind of high density vanadium-inhibition agent composition and method of making the same, mainly be suitable for the burning heavy oil boiler, can effectively suppress the corrosion that oxious component sulphur, vanadium, sodium etc. in the heavy oil cause.
Background technology
In the boiler of RF combustion chamber, often owing to materials such as sulfur-bearing, vanadium, sodium in the oil fuel cause corrosion, the high temperature corrosion that causes as, the low temperature corrosion that causes because of sulfuric acid with because of vanadium compound etc.High temperature corrosion occurs in the superheater tube of boiler, and the position that the combustion chamber wall equitemperature is higher results from Vanadium Pentoxide in FLAKES (V
2O
5).V
2O
5Fusing point is about 670 ℃, and when being lower than this temperature, Vanadium Pentoxide in FLAKES is solid state, can not stick on the tube wall, but after surpassing this temperature, and its just melting and adhere to tube wall will be corroded at its adhesion section.In addition, if V
2O
5And Na
2SO
4When existing simultaneously, then generate low melting component, this compound is easier to stick on the tube wall, and makes the corrosion aggravation.Therefore need to add vanadium-inhibition agent, raising comprises V
2O
5At the fusing point of interior oil fuel material, thereby prevent its easy fusion and adhere to tube wall, cause corrosion.
But vanadium-inhibition agent concentration of the prior art is lower, generally is lower than 20%, and large usage quantity is difficult for placing, uncovered easy volatilization, dry and hard, and the time, precipitation also can appear in long words bottom, and, meet the easy breakdown of emulsion layering of the water capacity.
Therefore, need the higher vanadium-inhibition agent of a kind of concentration of exploitation, and can place for a long time, can not meet the layering of water breakdown of emulsion.
Summary of the invention
The purpose of this invention is to provide a kind of high density vanadium-inhibition agent composition, this vanadium-inhibition agent composition energy and V
2O
5The reaction back generates high melting compound, plays preventing that vanadium compound is attached to the effect of tube wall, prevents that fouling from generating and eliminating the effect of fouling thereby play, and this vanadium-inhibition agent composition consumption is less, can place for a long time, also can not meet the layering of water breakdown of emulsion.
For achieving the above object, the invention provides a kind of high density vanadium-inhibition agent composition, this vanadium-inhibition agent composition is the suspension liquid system, it comprises following raw materials in percentage by weight:

Described solvent is a machinery oil, as 20#, 32#, 46# machine oil, can add in the middle of the heavy oil with arbitrary proportion, and therefore adding can be easily as the vanadium-inhibition agent composition of solvent and the heavy oil thorough mixing with these machinery oil, makes vanadium-inhibition agent to be used effectively.
Described magnesium powder purity reach 90% and more than, the sieve size of magnesium powder is 100 orders ~ 300 orders.
Described dispersion agent is selected any one or more than one the mixture in Witconol 2301, acetone, oleic acid, the benzene sulfonic acid sodium salt.
More than in described auxiliary agent selection phosphoric acid ester series, peregal series, sapn series, the tween series any one.
Above-mentioned high density vanadium-inhibition agent composition, wherein, in the described suspension liquid, solid grain size makes its viscosity and degree of adhering to fully reduce less than 10 microns.
The present invention also provides a kind of high density vanadium-inhibition agent preparation of compositions method, and this method comprises following concrete steps:
Step 1 is put into the magnesium powder in the middle of the solvent by the formula ratio of claim 1, stirs, and adds Glacial acetic acid, and the adjusting acidity value is pH=7 ~ 8;
Step 2 under agitation adds after dispersion agent is uniformly dispersed, and adds manganese oxide, cupric oxide, and temperature was heated between the 80-110 degree isothermal reaction 3-4 hour, added auxiliary agent, and agitation grinding obtains the suspension liquid system, i.e. high density vanadium-inhibition agent composition.
Vanadium-inhibition agent composition of the present invention is to add in the heavy oil with the form of slurry oil, therefore the thorough mixing of vanadium-inhibition agent and heavy oil could play due effect more efficiently, the employed solvent 20# of vanadium-inhibition agent composition of the present invention, 32#, 46# machinery oil can add in the middle of the heavy oil with arbitrary proportion, therefore with its be solvent product of the present invention also can with heavy oil with good mixed, make V in magnesium powder and the heavy oil
2O
5High melting compound Mg (VO is produced in fully reaction
3)
2Thereby, avoid the V in the heavy oil
2O
5Easily fusion and adhere to tube wall and cause corrosion.
In a word, high density vanadium-inhibition agent provided by the invention has high efficiency, and the concentration height easily mixes, and good fluidity can not adhere at wall of container, and good stability can be placed for a long time, meets water chance air and is not easy the skinning that lumps, the convenient preservation.
