Abstract
The invention provides a separation agent for washing oil sand with water. The separation agent is prepared from the raw material components in percentage by weight: 0.5%-2.0% of sodium silicate, 0.1%-0.5% of sodium carbonate, 0.05%-0.1% of alkali, 0.1%-1.0% of surfactant and the balance of water. The pH values of the sodium silicate and sodium carbonate in the separation agent are as high as 9-10 in an inorganic electrolyte, so the separation agent has good effects of emulsifying oil, suspending dirt and preventing dirt redeposition; the alkali in the agent can react with acidic materials in the oil to generate surface active substances, thus accelerating separation among oil, sand and mud; and the surfactant in the agent can rapidly separate oil, sand and mud within a short reaction time at a quick separating rate, thereby lowering the production cost.
Description
Technical field
The present invention relates to oil-sand separation pharmaceutical techniques field, refer specifically to a kind of washing oil-sand separation medicament。
Background technology
The mineral such as oil-sand is a kind of Colophonium, husky rich ore clay and the mixture of water, and its Asphalt Content is 10～12%, husky and clay account for 80～85%, and remainder is the water of 3～5%, is a kind of unconventional resource.Along with conventional oil exploitation and the continuous of international oil price are risen, oil-sand, as a kind of important non-conventional oil resource, obtains the attention of national governments day by day.Crude oil chemical group poling in oil-sand is complicated, predominantly condensed-nuclei aromatics and macromolecule hydrocarbon, resin and asphalt content is high, owing to its viscosity is high, molecular weight is big, causes its mobility and intersolubility poor, and the most easily deposition absorption is on institute's contact surface, it is not readily separated, brings many difficulties to oil-sand recovery process.
Washing separates oil-sand separation technology, because its technical process is simple, cost of investment is low, so isolation technics is often used to exploit oil-sand, when washing separates oil-sand, washing separates medicament and plays vital effect in whole separation process, and washing separates the quality of medicament and directly influences separating effect and oil yield.At present, existing washing separation medicament is during separating oil-sand, owing to surfactant therein needs could act in the case of high temperature (80 DEG C-95 DEG C), cause the overall separation process reaction time longer, it is generally required to 40-60min, separating rate is relatively slow, adds production cost.
Summary of the invention
The technical problem to be solved is to provide a kind of washing oil-sand separation medicament.
For solving the problems referred to above, a kind of washing oil-sand separation medicament of the present invention, the raw material components of described separation medicament and the percentage by weight of each component are, sodium silicate 0.5%-2.0%, sodium carbonate 0.1%-0.5%, bases 0.05%-0.1%, surfactant 0.1%-1.0%, remaining as water.
A kind of washing oil-sand separation medicament of the present invention, the raw material components of described separation medicament and the preferred weight percent of each component are that sodium silicate 0.8%-1.5%, sodium carbonate 0.2%-0.4%, bases 0.06%-0.08%, surfactant 0.3%-0.7%, remaining as water.
Described bases be in potassium hydroxide, sodium hydroxide any one.
Described surfactant is fatty alcohol-polyoxyethylene ether, fatty alcohol sulfate, benzalkonium chloride, lauryl amine ethylsulfonic acid sodium one therein.
The present invention compared with prior art has the advantage that
1, the sodium silicate in medicament of the present invention and sodium carbonate pH value in inorganic electrolyte are up to 9-10, have good emulsified fat and soil suspension and prevent the effect of soil redeposition.
2, the bases in medicament of the present invention can react with the acidic materials in oils, generates the material with surface activity, thus promotes the separation between oil, sand and mud.
3, the surfactant in medicament of the present invention (50-65 DEG C) at a lower temperature can be rapidly separated oil, sand and mud, and the response time is 10-20min, and separating rate is fast, thus reduces production cost.
