The invention has the advantages of simple compositions, good stability, energy-saving and environmental protection; and when being added into the heavy oil, the invention can remarkably improve the heavy oil fluid performance, enhance the combustion efficiency of the heavy oil, avoid coking and incrustation of a hearth, lower the corrosion of combustion equipment and save a cleaning procedure of the combustion equipment.
Description
Technical field
The present invention relates to additive for heavy oil, relate in particular to the heavy oil energy-saving environmental-protection additive.
Background technology
Heavy oil is as a kind of important heat resource, because characteristics such as its high heating value, low price are widely used in industry and civil heat supply system.But there are a lot of defectives in common heavy in application, big as system viscosity, and is mobile poor, incomplete combustion, and thermo-efficiency is on the low side, and fume emission exceeds standard, and has problems such as low temperature corrosion and high temperature corrosion, has caused the waste of the energy and the pollution of environment.Particularly along with the improving constantly of petroleum refinery process deep processing state of the art, furol viscosity alters a great deal, and quality is extremely unstable, and the present is often caused oil tank big area gum deposit, can't discharge.Parts carbon distributions such as heavy oil preheater, strainer carbon distribution block, burner and coking can't normally move.In order to solve the defective that above heavy oil in use exists, take in heavy oil, to add an amount of additive, reduce heavy oil system viscosity, improve the heavy oil combustion state, facts have proved it is a kind of effective solution and fuel-saving measures.Present additive for heavy oil adopts water and emulsifier mix system more, though help reducing the system viscosity after making emulsification heavy oil, but under equal sufficient combustion condition, the existence of large quantity of moisture can absorb heat on the contrary, its actual combustion heat value can't improve, and thermo-efficiency reduces on the contrary, even may produce oily water separation and extinguish, and additive formulations component complexity is unfavorable for long term storage stability.Thereby this type of additive for heavy oil also is difficult to reach effect in energy saving and environmental protection.
Summary of the invention
The object of the present invention is to provide a kind of component simple, easy to prepare, stability is strong, in heavy oil consumption few, have good burning performance, blowdown flow rate is few and can solve the heavy oil energy-saving environmental-protection additive of the high low temperature etching problem of combustion equipment.
For achieving the above object, technical scheme of the present invention comprises:
A kind of heavy oil energy-saving environmental-protection additive is characterized in that: by AEO
3, magnesium naphthenate, solvent oil mix and form, the weight ratio of described each component is: AEO
325 ~ 35 parts, 45 ~ 55 parts of magnesium naphthenates, 10 ~ 30 parts of solvent oils.
Described solvent oil is an industry varsol oil commonly used.
The preparation method who produces above-mentioned heavy oil energy-saving environmental-protection additive is: according to prescription desired raw material consumption, with AEO
3Add mixing kettle, be warming up to 50 ~ 60 ℃, add the magnesium naphthenate and the solvent oil of metering, mixed 0.5 ~ 1 hour, left standstill 10 minutes, can make the heavy oil energy-saving environmental-protection additive.
The consumption of described heavy oil energy-saving environmental-protection additive is 0.04% ~ 0.08% of a heavy oil quality.
The present invention adopts AEO
3Nonionogenic tenside can significantly reduce the heavy oil surface tension, realizes the homogeneous dissemination to colloid, micro-moisture in the heavy oil, effectively reduces the heavy oil viscosity, improves atomizing state, improves heavy oil combustion efficient, simultaneously AEO
3Chemical environment susceptibility to use is low, and stability is strong; With the metallorganics magnesium naphthenate is ignition dope, improve the dispersion state of heavy oil, heavy oil combustion there is positive catalysis, improve heavy oil combustion efficient, simultaneously can generate dystectic vanadic acid magnesium with the v element chemical combination in the heavy oil again, be ash content and discharge, avoid low-melting vanadic acid sodium to stick to and produced high temperature corrosion in the burner hearth, reduced in the tail gas acid amount in addition, reduced the low temperature corrosion of equipment and the pollution of environment; As the compatibility blender, above-mentioned two kinds of function ingredients are mixed with solvent oil, give play to better synergy.Through using checking, show add additive of the present invention after, heavy oil is carried convenient, nozzle does not have obstruction, burner hearth does not have dross, need not to shut down cleaning and safeguards that the burning intensity of a fire is vigorous; Efficiency of combustion improves simultaneously, and exhaust temperature descends, and the exhaust emissions amount reduces, and has reached the purpose of energy-conserving and environment-protective, has improved the service efficiency of equipment simultaneously.
The present invention has that component is simple, easy to prepare, stability is strong, in heavy oil consumption few, have good burning performance, blowdown flow rate is few and can solve the advantages such as high low temperature etching problem of combustion equipment.
Embodiment
The invention will be further described below in conjunction with embodiment, but scope of the present invention is not limited in the scope of embodiments, and those skilled in the art can improve, and it all within the scope of the present invention.
Embodiment 1, takes by weighing 25g AEO
3Be warming up to 50 ℃ in the adding stirring tank, add 45g magnesium naphthenate and 30g solvent oil, mix and stir 0.5h, left standstill 10 minutes, promptly make desired heavy oil energy-saving environmental-protection additive, products obtained therefrom is pale brown look oily thick liquid.
Embodiment 2, take by weighing 30g AEO
3Be warming up to 60 ℃ in the adding stirring tank, add 50g magnesium naphthenate and 20g solvent oil, mix and stir 0.5h, left standstill 10 minutes, promptly make desired heavy oil energy-saving environmental-protection additive, products obtained therefrom is pale brown look oily thick liquid.
Embodiment 3, take by weighing 35g AEO
3Be warming up to 50 ℃ in the adding stirring tank, add 55g magnesium naphthenate and 10g solvent oil, mix and stir 1.0h, left standstill 10 minutes, promptly make desired heavy oil energy-saving environmental-protection additive, products obtained therefrom is pale brown look oily thick liquid.
During use the heavy oil energy-saving environmental-protection additive of 0.04%～0.08% heavy oil weight percent and heavy oil is heated to mix about 80 ℃ to stir and got final product in about 0.5 hour.
Heavy oil energy-saving environmental-protection additive 0.5g that above embodiment is made and 1000g heavy oil mixed sample, its surface tension, viscosity, combustion heat value and burning are generated the acid substance amount test, and compare test result with common heavy and see the following form 1;
Table 1
| Interventions Requested | Common heavy | Add additive heavy oil |
