Abstract

An efficient liquid emulsifier for heavy oil is prepared from sodium hydroxide, xylenol,sorbitol anhydride, methanol, sodium alginate and water through proportioning. It is added to heavy oil in a ratio of 100% (heavy oil) : 1% (emulsifier) : 15-25% (water). The emulsified heavy oil features high stability, easy storage without demulsification, no separation of oil from water, less consumption of emulsifier, low cost, full combustion, high thermal efficiency, no generation of black smoke, long service life of equipment, less environmental pollution and saving oil by 15-20%.

Description

Efficient liquid emulsifier for heavy oil

The present invention relates to a kind of efficient liquid emulsifier for heavy oil.

Heavy oil is industrial enterprise units such as heat power plant, refinery, chemical plant, glasswork, Steel Plant fuel commonly used, and year consumption is very big.Solving heavy oil consumption effectively is the problem of the research of relevant department's effort in recent years.

Known to me, prior art as (" heavy oil mixed with water function emulsifying agent " its blending process process complexity that the CN1067593A Chinese patent is openly reported, heavy oil mixed with water rate only 10%, rate of economizing gasoline is low, the storage time is short.

The objective of the invention is:

A kind of preparation heavy-oil emulsifying agent easily is provided, and its heavy oil mixed with water rate is up to 15%-25%, and the storage time reached more than 6 months.The combustion heat value height prolongs the combustion equipment life-span, reduces environmental pollution, and oil-saving effect is (15%-20%) obviously.

Manufacture method of the present invention is: (is example with 100 kilograms of liquid heavy-oil emulsifying agents)

The 82.5 kilograms of 8 kilograms of sodium hydroxide of adding (NaOH) of fetching water become aqueous sodium hydroxide solution, add 4 kilograms of xylenol (CH3) 2C6H3OH and 2 kilograms of sorbitol anhydrides (SMS) again, add 3 kilograms of methyl alcohol (CH3OH) after the heating again and carry out chemical reaction, then add 0.5 kilogram of sodium alginate (C6H7O6Na) n phased soln again.Stir, filter and promptly make the alleged efficient liquid emulsifier for heavy oil of the present invention through powerful.

The emulsification program is:

H2O \ dissolving-＞xylenol+sorbitol anhydride-＞methyl alcohol-＞sodium alginate-＞

NaOH/ Hybrid Heating reaction dissolving

The powerful stirring-＞filter-＞finished product

My its color of efficient liquid emulsifier for heavy oil of invention is a setting sun redness, and standing storage is never degenerated, sediment-free.With the heavy oil mixed with water amount big (15%-25%) of its preparation, viscosity reduces, good fluidity; be easy to burning, form atomized particles at the burner nozzle place, mix with even air; make emulsification heavy oil independently microexplosion separately, the contact area of increase and air molecule impels burning fully; rate of combustion can reach more than 97%; rate of economizing gasoline can reach 15%-20%, and increases furnace temperature, reduces the preheating temperature of fuel oil; reduce the black smoke discharging, have the thermal efficiency of raising and environment protection effect.

Its flame mechanism of heavy oil after the efficient liquid emulsifier for heavy oil emulsification that I invent is as follows:

1. form the water-in-oil particulate immediately after stirring, anhydrous, oily interface takes place, and demulsifying phenomenon do not occur.

2. produce oil, water second emulsifying when stirring, make water in oil particulate littler, be easier to burning.Particulate after the atomizing after measured, diameter 5u accounts for 90%, diameter 5-10u accounts for 10% (droplet diameter after the general heavy oil atomizing is 10-500u, wherein accounts for 85% about 50u).

3. " microexplosion " that produce when burning increased firing level, is easy to perfect combustion, reduces the content of carbon monoxide, can improve 15 degrees centigrade of furnace temperature.

4. this emulsifying agent has catalytic property, has improved molecular activity, and making the macromole thermal cracking of heavy oil is small molecules, forms the incendiary condition that more helps, and reduces surplus air.Its flame is mazarine.

5. remaining carbon reduces 85%, reduces in the stove in a large number and the interior carbon distribution increase of chimney boiler hot exchange efficiency, reduces boiler cleaning and maintenance times and expense.

6. because of being surrounded by the water of 15%-25% in the oil, water easily resolves into hydrogen and oxygen after being heated, provide once more to supply incendiary oxygen, has reduced the generation of dense smoke, oxycarbide, oxynitride relatively, reduces atmospheric pollution significantly.

7. the content of the heavy oil sulphur after the emulsification has reduced to 0.37%.In addition, because viscosity reduces, its required operating pressure also weakens thereupon, helps prolonging the time limit of service of combustion equipment.

Claims

A kind of efficient liquid emulsifier for heavy oil, red 1%, the water (surplus) of sodium hydroxide 8%, xylenol 4%, sorbitol anhydride 2%, methyl alcohol 3%, sodium alginate 0.5%, the setting sun.

The ratio of emulsifying agent and water and heavy oil is: 1%: 15%-25%: 100%.
