Description

Heavy fuel additive {The serviceability fuel additionagent}

The present invention relates to a heavy fuel additive, more specifically, a heavy fuel additive and an emulsified heavy fuel obtained at the same time to obtain a high efficiency heavy fuel additive with a small amount of raw material is very stable in use, it is not deoiled even in long-term storage, A heavy fuel additive that is heated to 100 ° C. to prevent oil and water from being separated by vibration, even in a centrifuge under heating.

In recent years, petroleum is the most used and the most popular of the disposable energy. Conflicts between its mass use and globally limited storage quantities have resulted in a rise in oil prices as a major contributor to the global economy. Efficient and sufficient use of petroleum resources in fuels is a common task now undertaken by engineers from around the world.

The use of heavy oils (including asphalt-containing heavy oils, high solids waste oils and recovered oils) which are not sufficiently burned is one of the most urgent tasks to be solved. When flame retardant heavy oil is combusted, it generates a lot of oxysulfide, nitric oxide, carbon monoxide, coal, and dust, and when released into the air, serious pollution occurs.

Much research has been done on how to add additives to heavy oils to emulsify them. The emulsification through the method using only nonionic surfactants was not very effective (for example, CN 1007543), and a lot of complex emulsifiers were used.

For example, CN 106759 (Application No. 91106720) is prepared using various nonionic surfactants such as sorbitan fatty acid esters and alkylphenol ethers, and sodium benzenesulfonate, amide, Schiff base type ionic surfactants and phenols. It is an emulsifier.

Emulsified heavy oil is produced only when used and used immediately. If stored for 12 days, it does not de-emulsify. CN 1185479 (ZL96121448) contains 79.7 to 96% heavy oil, 3.99 !, with 0-15% perylene diamine as well as nonionic surfactants (required for HLB values ≤8) and ionic surfactants (cationic and anion). Immediately use emulsified heavy oil, which is mixed with 20% water and 0.01 ~ 0.3% emulsifier. Various surfactants were used in the above patent data, but did not satisfy the safety of emulsification.

And there are ways to improve the partial performance by adding auxiliaries. For example, CN 1102669 and CN 1260379 are added with potassium oxymanganate and potassium nitrate as strong oxidizing agents to sufficiently burn and oxidize. 20 to 35% of petroleum is added to CN 1282779 as a combustion promoter, There is an attachment of lunglocene, an iron chemical. The current technology has its own characteristics, but the shortcomings are remarkable. For example, it is withdrawn soon after many patent applications and authorizations due to some emulsification effects, poor stability after emulsification, failure to consider preservation, too many kinds of raw materials, or high cost. There were all sorts of problems thrown away.

Therefore, the object of the present invention was devised in view of the above problems, and the heavy fuel additive and the emulsified heavy fuel obtained at the same time as obtaining a high-efficiency heavy fuel additive with a small amount of raw materials are very stable in use, and deoiled even during long-term storage. The present invention provides a heavy fuel additive which does not separate oil and water even by heating to 100 ° C. and vibrating or even centrifugation in a heated state.

The present invention is a means for achieving the above object, the heavy fuel additive is 50 to 500% by weight of caustic soda, 50 to 500% by weight of calcium chloride, 5 to 500% by weight of sodium alginate, 1000% by weight of magnetized water in 2500% by weight Consisting of proportions,

Caustic soda can be replaced with sodium nitrate or sodium chloride, calcium chloride with calcium sulfate or calcium phosphate, sodium alginate with potassium alginate or xanthan gum,

The heavy fuel additive contains a compound of magnesium particles or a compound of chlorine particles, and the amount of the magnesium particle compound is 17 to 60% by weight, and the amount of the chlorine particle compound is 31 to 115% by weight. It is done.

As described above, according to the present invention, a high efficiency heavy fuel additive may be manufactured using a convenient formulation formula and a small amount of raw materials.

In addition, through the blending method of the heavy fuel additive and the emulsified heavy oil according to the present invention it is very easy to obtain the emulsification effect of the oil-based capsule-like water droplets of the emulsion and can sufficiently combust the heavy oil.

In addition, heavy fuel additives and emulsified heavy fuels have very good stability when used and do not deoil even when stored for a long time. They are heated up to 100 ° C, and the oil and water cannot be separated even by centrifugation in a heated state. It is.

Hereinafter, the windy embodiment of the present invention will be described in more detail.

First of all, the object of the present invention is to provide a heavy fuel additive having few original items and excellent performance.

The main raw materials used in the present invention for this purpose are caustic, calcium chloride, sodium alginate and magnetized water. Weight ratio of heavy fuel additives

Caustic Soda: 50 ~ 500% by weight

Calcium chloride: 50-500 wt%

Sodium alginate: 5-150 wt%

Magnetized water: 1000 wt%

Caustic soda (NaNOH) can be replaced by sodium nitrate (NaNO ₃ ) or calcium softened (NaCl ₂ ) with potassium alginate (Alginic acid potassinm) or xanthan gum. The magnetized water as described above is water formed through a magnetization process in a magnetic field.

Through many experiments, the following formulation is chosen.

Caustic Soda: 100-400 wt%

Calcium chloride: 100-400 wt%

Sodium alginate: 8-100 wt%

Magnetized water: 1000 wt%

Compounds (usage amount 17-60 weight) or chlorine ion compounds (usage use 31-115 weight) can also be used for magnesium ion other than the said component.

The manufacture of heavy fuel additives is all made by mixing the above ingredients. This additive is an ionic additive that is an ivory liquid.

When the heavy fuel additive of the present invention is used, the weight ratio of heavy fuel and magnetized water is the most suitable for heavy fuel: magnetized water = 50 to 90:50 to 10 and 70 to 80:30 to 20.

The water used must also undergo magnetization of the magnetic field. The amount of heavy fuel additive used is that 100% of magnetized water is added to the heavy fuel, and the heavy fuel additive is most suitably 0.01 to 0.45 and 0.20 to 0.40.

The present invention is used in the object to be treated, that is, the heavy oil mentioned there is no particular limitation. Heavy oils, crude oils, quasi-petroleum, petroleum and petroleum heavy oils of petroleum heavy hydrocarbon oils and waste oils generated in various industrial facilities can all be treated.

The process for producing emulsified heavy oil is well known by those skilled in the art, adding magnetized water, mixing heavy petroleum oil, and then adding additives. This can be seen clearly when manufacturing in laboratory glass containers. When only heavy oil and magnetized water are present, the oil and water limits are clear and do not change when mixed. After adding the additive of the present invention, the heavy oil, the emulsion heavy oil prepared with magnetized water is the only encapsulated emulsion fuel. The additives disperse the water particles evenly in heavy oil, form a droplet-type emulsifier in the oil, and the diameter of the emulsifier particles is 5-25 μm.

When viewed through a microscope, water droplets are evenly distributed in heavy oil, and a film is formed outside the water droplets to enclose the water droplets. The water drops sparkle white light under the light. In addition to the water droplets accumulated on the membrane, it is black heavy oil and appears in capsule form. You can also see the picture accurately.

There is no segregation of oil and water even after long-term storage of emulsified heavy oil. The oil and water emulsification is the same as the first time even after the heavy oil is heated to 100 ° C. Oil and water are not separated even by heating to 80 ~ 100 ℃ of heavy oil. At the same time as the storage, the corrosion test is carried out, which shows that there is no corrosion phenomenon.

When the emulsion heavy oil burns, the water particles generate a strong explosion due to the high temperature, and are completely burned by changing the finer to sufficiently burn the oil particles through the topping, so that there is no residue. As a result of the combustion test, the gas content such as carbon monoxide and sulfide is greatly reduced and the thermal efficiency is significantly higher. Under the same combustion conditions, when the emulsion heavy oil and the crude heavy oil produced by the present invention burn separately in the combustion furnace, the fire of the combustion of the emulsion heavy oil appears in bright yellow in the observation holes on the front and side of the combustion furnace, and the heavy oil is Incomparable with just a red complaint.

Hereinafter, described in more detail through an embodiment according to the present invention.
