Description
Technical field
The present invention relates to mink cell focus technical field, more particularly to one kind are separated from heavy oil field for the separation of heavy oil field
Microemulsion extractant and usage.
Background technology
Heavy oil field, is the general designation of a kind of unconventional energy resource, includes oil shale, oil-sand, greasy filth and mink cell focus etc..
Oil shale is a kind of sedimentary rock, containing solid organic matters in the skeleton of its inorganic mineral.Its organic substance is main
For kerogen, insoluble in petroleum solvent, also containing a small amount of asphalitine.Oil shale isolation air is heated to 500 DEG C or so, its
Kerogen pyrolysis generation shale oil, water, semicoke and carbonization gas.Thermal decomposition product shale oils are like natural oil, after reconciliation,
It can be used as bunker fuel oil, by techniques such as hydrofinishings, the light-end products such as gasoline, diesel can be obtained.
Oil shale is as a kind of important unconventional energy resource, and reserves are huge, according to incompletely statistics world's oil shale resources amount
It there are about 10,000,000,000,000 tons.About 500,000,000,000 tons of shale oil is converted to, more than 2 times of Global Oil stock number (about 270,000,000,000 tons).China
About 719,900,000,000 tons of oil shale resources reserves, are converted to about 47,600,000,000 tons of shale oil, and technologically recoverable reserves are 3,000,000,000 tons.As oil
The supplement energy, oil shale development prospect is wide.
In greasy filth, i.e. oil exploration, exploitation, refining, clear tank, storage and transport process, due to accident, evaporating, emitting, dripping or leaking of liquid or gas, natural subsidence
Etc. reason, the oily sludge of substantial oil or oil product and soil, water or the formation of other impurity.Different according to the origin cause of formation, greasy filth is usual
It is divided into：Ground sludge, tank bottom oil sludge, ground oil spilling, oil plant oily sludge etc..Wherein, tank bottom oil sludge typically contains about 25%
Water and 5% inorganic matter, such as silt particle, remaining 70% is hydrocarbon；Pass through appropriate isolation technics, hydrocarbon
The rate of recovery can reach more than 98%, and it is larger to recycle value.According to statistics, the annual total output of Shengli Oil Field greasy filth is
116.27kt, it is contemplated that the greasy filth that each elephant in the whole nation produces will be up to tons up to a million every year；The oil content of greasy filth for 10%~
30%, water content is 20%~50%, based on average oil content 20%, there are about more than ten ten thousand tons of crude oil every year and is deposited in greasy filth,
Cause a large amount of wastes of petroleum resources.
The volatile ingredient of greasy filth petrochina, which enters air, can pollute air；Oil in greasy filth then can with rainwater into water body
Cause seriously to pollute, destroy the ecosystem of water；Oil in greasy filth enters soil, microorganism that can be to soil itself and soil
Plant ecosystem produces harm；More seriously many harmful substances in crude oil have mutagenesis and carcinogenicity, by straight
Connect and can seriously be damaged to human body health care belt with degradation pathways.Therefore, economic, environmentally friendly, the practical treating method and apparatus of research and development,
Oil fully in recycling greasy filth, and the resid amount after processing in soil is reached state-set standard, by with good warp
Ji and environmental benefit.
Oil-sand refers to the mixture that the clast of veneer of crust or rock are formed with water contained therein and viscous crude or pitch
General designation, reserves are very huge, are current important potential petroleum resources a kind of in the world.Under normal circumstances, dripped in oil-sand
Mass fraction shared by the heavy oil such as green grass or young crops is 5-30%.More than 90% oil-sand is distributed in north America region in the world, mainly the U.S.
With Canada area；Also there is billions of oil-sands in Indonesian southeast, has great potentiality to be exploited.In international stone
Oily demand is growing and in the case that oil price remains high, and develops in oil-sand the heavy oil asphalt resource being enriched with, can conduct
The substitute of petroleum resources, has a vast market prospect and economic benefit.
Due to its high viscosity and stronger affinity, traditional thermokalite WATER-WASHING METHOD is difficult to extract the pitch in oil-sand.Now
The solvent extraction of the main operating condition higher, gentle to oleophylic ore using organic efficiency and good applicability.However,
Solvent extraction there are problems that at present, the mineral entrainment of high-content such as occurs, and the dosage of solvent is big, and multiple-stage solvent extraction is logical
High-energy source during solvent is distilled to recover is often resulted in consume.
China's oil insufficiency of supply-demand increases year by year, the oil contradiction long-term existence that supply falls short of demand.Develop oil-sand, oily page
The mink cell focus ore resources such as rock, greasy filth, substitute part conventional energy resource, alleviate China's Pressure on Energy, are that national policy will be encouraged from now on
Direction.
