Abstract
The present invention relates to chemical technology, and proposes the production process and modifier of water modified fuel oil. The water modified fuel oil producing process includes the following steps: compounding water solution of modifier; preheating petroleum residual oil; mixing the water solution of modifier, the petroleum residual oil and light oil; and heating to produce petroleum residual oil hydrating reaction. The modifier comprises sodium cation compound and phospholipid, and the sodium cation compound may be sodium salt of organic acid or inorganic acid, sodium oxide or sodium hydroxide. The water modified fuel oil has the advantages of no oil-water separation, high combustion value and high burning performance.
Description
Technical field
What the present invention proposed is the production method and the properties-correcting agent thereof of a kind of water modified fuel oil of chemical field.
Background technology
Before the present invention proposes, have by in oil fuel, adding the patent application that entry changes its combustionproperty, but need to add properties-correcting agent.Usually the properties-correcting agent that is added is emulsifying agent, and the effect by emulsifying agent mixes profit, forms the oil-water mixture of water-in-oil or oil-in-water state.This oil-in-water type oil fuel is easy to generate oily water separation and loses use properties in the process of storing, especially be easy to generate physics and chemistry especially at the condition of high temperature or low-temperature condition and change and cause oily water separation.And, owing to oil body is that emulsified state exists, in use, need carry out thermal pretreatment to burner could normally use, under the situation of emulsified state difference, the water vapor in its combustion processes also can absorb heat and reduce temperature of combustion, causes fuel heat utilization to reduce.Owing to as above reason, add water oil fuel and do not obtain general application.
Summary of the invention
Have the easy oily water separation of water modified fuel oil now in order to overcome, the shortcoming of combustionproperty difference, the present invention proposes a kind of production method and properties-correcting agent thereof of water modified fuel oil.The properties-correcting agent that this method utilization is provided can be produced the water modified fuel oil that storage process does not produce oily water separation and has good burning performance.
The present invention solves the scheme that its technical problem takes: finish through modifier aqueous solution preparation process 1, petroleum residual oil preheating procedure 2, modifier aqueous solution, petroleum residual oil and light residual oil mixed processes 3 and heating residual oil hydration reaction operation 4.
Properties-correcting agent is sodium cation compound and phosphatide.Sodium cation compound comprises the oxide compound and the oxyhydroxide of organic acid and mineral acid sodium salt and sodium.
Beneficial effect is: owing to the water modified fuel oil that adopts properties-correcting agent provided by the present invention to make can not produce oily water separation, and can reach water and participate in and burn, so its fuel value height has good burning performance, the suitable oil that acts as a fuel uses.
Description of drawings
Fig. 1 is a water modified fuel oil producing method process flow sheet of the present invention
Among the figure, 1. modifier aqueous solution preparation process, 2. petroleum residual oil preheating procedure, 3, modifier aqueous solution, petroleum residual oil and light residual oil mixed processes, 4, heating residual oil hydration reaction operation.
Embodiment
1. modifier aqueous solution preparation process:
Add sodium cation compound 0.1～0.5Kg in 100Kg water, phosphatidase 10 .1～0.5Kg forms modifier aqueous solution;
2. petroleum residual oil preheating procedure:
With the steam preheating of heating, temperature is controlled between 50～80 ℃, makes petroleum residual oil reach melting state with petroleum residual oil.
3, modifier aqueous solution, petroleum residual oil and light residual oil mixed processes:
Petroleum residual oil and the light residual oil of modifier aqueous solution with the process preheating is injected into respectively in the reactor, and the cooperation ratio is: modifier aqueous solution 10～80Kg, petroleum residual oil 90～20Kg, light residual oil 2～5Kg;
4, heating residual oil hydration reaction operation:
In reactor under the state that stirs the heated oil water mixture, 30～50 ℃ of Heating temperature scopes, time range 20～50 minutes is put more than 12 hours only, makes water and oil form molten state altogether, becomes the finished product water modified fuel oil.
The experiment proved that: adopt the made water modified fuel oil of the inventive method under the normal temperature state, when oil, when the water ratio reaches 25: 75, can long storage, and the oily water separation phenomenon does not take place.
Adopt the made water modified fuel oil of the inventive method and show comparing burning under the equal combustion conditions in steam boiler without the petroleum residual oil of modification: the steam boiler of two tons of water capacities reaches under 1 atmospheric situation, directly burn the 35 minutes used time of residual oil, used residual oil 57.9Kg, reach the equal 23 minutes used time of effect metabolic water modified fuel oil, used water modified fuel oil 48.25Kg, time has been used 12 minutes less, oil fuel has been used 9.65Kg less, the water participation is described and burns (oil fuel water ratio 75%).
The water modified fuel oil Analysis on Mechanism:
Because the made water modified fuel oil of the present invention is not resolved in lower temperature conditions, does not vaporize when being heated to 100 ℃, illustrates that water and oil are not emulsified states.Because employed modifier aqueous solution can form water molecules free hydrogen ion and hydroxide ion, and strong with oil molecule formation hydrogen, thus can make water and oil be in codissolved state, thereby, can not produce oily water separation; Water and hydrocarbon polymer are under coexistence incendiary state, and water is subjected to the heat effect of hydrocarbon combustion to decomposite hydrogen atom and combines the burning and the evolution of heat with carbon monoxide, so improved fuel value, has improved combustionproperty.The effect of phosphatide is as the emulsifying agent of residual oil aquation and catalyzer, improves the profit avidity, and keeps profit to be in the state of mixing for a long time.
Embodiment
Sodium cation compound adopts yellow soda ash and 1: 1 mixture of SODIUMNITRATE, the mixture 0.2Kg of dissolving sodium cation compound in 100Kg water, and phosphatidase 10 .3Kg makes the 100.5Kg modifier aqueous solution.
The material fiting ratio example is: modifier aqueous solution 75Kg, and petroleum residual oil 25Kg, light residual oil 0.3Kg, can obtain the 100.3Kg water ratio through reaction is 75% water modified fuel oil.
