Abstract

The invention relates to a heavy oil emulsifier and a preparation method thereof. The emulsifier enables water doped heavy oil to have a long stable period and stably maintains for 3-5 months without oil-water separation; an additive based on water greatly dilutes the viscosity of heavy oil and improves the fluidity of the heavy oil, so the heavy oil sprayed from a nozzle has a large dispersibility, fully contacts with air and can be completely combusted, thereby black smoke is eliminated, and environmental protection is facilitated; the water addition rate of the heavy oil is high and can reach 20-50%, the use amount of the additive is 1-30%, and the oil saving rate reaches 15-30%, so the fuel resource is saved; the oil nozzle cannot be coked, and a device pipeline cannot be corroded, so the maintenance frequency of the nozzle is greatly reduced; and the fuel cost per use unit is reduced, and the maintenance cost of a boiler and other combination devices is also reduced.

Description

A kind of heavy-oil emulsifying agent and preparation method thereof
Technical field
The invention belongs to additive for heavy oil field, particularly a kind of heavy-oil emulsifying agent and preparation method thereof.
Background technology
At present, energy shortage is the major issue that countries in the world face, and how to effectively utilize heavy oil also becomes the focus paid close attention to various countries thereupon, and the price of heavy oil is low, source has certain calorific value extensively, again, is therefore a kind of main source of fuel.Heavy oil also claims residual oil, and being crude oil extracts the Residual oil after distillate through normal pressure or vacuum distillation apparatus, or by the crack resid extracted out at the bottom of high-temperature pressurizing cracking evaporator tower, or by the two mixing, also or add the heavy crude fuel that appropriate crack resid makes.
The outstanding feature of heavy oil is that colloid, asphalt content are high, causes its viscosity large, poor fluidity, brings very large difficulty to exploitation and application.In addition, heavy oil is a kind of Residual oil, and therefore its viscosity is high, detrimental impurity content is high, complicated component.Containing detrimental impurity such as sulphur (S), sodium (Na), potassium (K), vanadium (V) in heavy oil, when residual oil is as fuel, the SO that sulfur-bearing composition generates 2, SO 3can react with NaCL, KCL Deng corrosives and generate Na 2sO 4and K 2sO 4, and vanadium is oxidized to V 2o 5.Work as V 2o 5, Na 2sO 4and K 2sO 4be deposited on hardware on the surface with molten state, serious vanadium corrosion mouth can be brought out.In heavy oil, Na, K equal size is higher, and it can cause metallic surface havoc to the thermal etching that equipment produces in combustion.
Therefore, often adopt physics, heavy oil that chemical process makes thickness becomes a kind of fluid at normal temperatures with good fluidity, to realize carrying out the object of heavy oil recovery, conveying and industrial combustion under the condition not having steam heating and companion's heat.The mining type of current viscous crude generally uses the methods such as injection thermal recovery, electrically heated oil reservoir, chemical viscosity reduction, wherein in the exploitation of viscous crude, accumulating, transportation, there is the unexistent advantage of additive method with the reducing viscosity by emulsifying technology chemical viscosity reduction that is representative and be subject to the common concern of people, there is very large development potentiality.
Emulsification heavy oil is exactly by the heavy oil of hot melt state, with the blended emulsification of the aqueous solution containing emulsifying agent under the mechanical effects such as high speed centrifugation, shearing, impact, form heavy oil milk sap, oil-in-water emulsion is formed for viscous crude general requirement, in the past water-in-oil-type is mainly for heavy oil milk sap, along with the raising that energy saving standard requires, its watering quantity constantly increases, and focuses on oil-in-water-type heavy oil mixed with water milk sap at present.Heavy oil emulsive technology effectively can reduce its viscosity, improve its mobility, improve many application performances of heavy oil, many fields such as viscous oil recovery and transport, industrial burnup, heavy oil fluid catalytic cracking, casting technique are now widely used in, and its range of application, also in continuous expansion, thus has wide market outlook.
Be such as must carry out purifying treatment to heavy oil before the GTCC power plant of fuel uses with heavy oil, namely use deionized water emulsification heavy oil, make the salt such as water-soluble Na, K be dissolved in water, then add special emulsifying agent water effective is removed, reach the object of purification heavy oil.Therefore, the dehydration effect of emulsifying agent directly affects the use of heavy oil and the operation of equipment.
Summary of the invention
The invention provides a kind of heavy-oil emulsifying agent and preparation method thereof, be to solve heavy oil detrimental impurity many, use after needing to utilize emulsifying agent purifying treatment; And viscosity is large, poor fluidity, combustion fumes are large and carbon deposit is many and additive does not affect the technical problem of temperature of combustion.
