Description
Technical field
The present invention relates to a kind of degreasers for disposing polluted water in oil, and in particular to a kind of viscous crude heat of resisting high temperature, high salt
Adopt sewage water degreaser and preparation method thereof.
Background technique
The viscosity of viscous crude is big, and the sewage treatment for exploiting generation is always to restrict one of the important link of its development.Crude oil warp
After the heat chemistry settling processing a period of time for crossing dehydration, silt and other mechanical admixtures enter sewerage together, make dirt
Total suspended matter in water reaches 20000mg/L or so.Larger difficulty is caused to sewage treatment.Meanwhile in order to enable super-viscous oil
Ground is given rise to, the substances such as some surfactants, such as sulfonate are added in oil recovery process, so that Produced Liquid needs
Breaking emulsion and dewatering causes a large amount of chemical agent to remain in sewage, and causing sewage, not only oil content is high, but also the stabilization of emulsion
Property is strong, so that sewage oil removing and purified treatment are increasingly complex.
Conventional treatment process (natural subsidence-coagulant precipitation-filtering) is difficult to obtain heavy crude heat extraction sewage effectively at present
Processing.Another method for removing oil-bearing wastewater Crude Oil is chemical method, that is, uses oil removing agent method.Degreaser substantially divides
For following two categories, element of the first species's multiplicity, deoiling effect is good, but there is preparation process complexity, anti-salt property are poor, higher cost
Disadvantage；Another kind of degreaser ingredient is single, and preparation method and technique are relatively simple, and the requirement to water quality is lower, but exists and remove
The disadvantage of oily effect difference.At present for the patent condensed oil sewage that is less, and being biodegradable of condensed oil sewage processing aspect
Degreaser is even more fewer and fewer.
Several novel seasons are proposed in " synthesis and the performance study that quaternary ammonium salt can decompose surfactant " of Liang Huihui
Ammonium type surfactant, and the synthesis condition and surface property of the quaternary ammonium salt surface active agent developed are ground
Study carefully.According to laboratory test studies have shown that the biodegradable surfactant of the dication containing acetal functionality is due to having
Annular rigid structure has heat resistance, while with the polar substances of oil droplets chemistry can occur for bis-quaternary ammonium salt cationic
Suction-operated and form bridging, coalescent deoiling, therefore the dication surfactant can be used for the sewage treatment of viscous crude.
Summary of the invention
The present invention provide in view of the deficiencies of the prior art a kind of resisting high temperature, high salt heavy crude heat extraction sewage degreaser and its
Preparation method, degreaser of the invention have preparation process is simple, at low cost, temperature-resistant anti-salt performance is good, resistance to salinity reaches
250000mg/L, heatproof is up to 250 DEG C, and the feature that deoiling effect is good, and the oil removal rate of heavy crude heat extraction sewage reaches 96% or more, compared with
Existing medicament improves 40% or more.
The invention discloses a kind of heavy crude heat extraction sewage degreasers of resisting high temperature, high salt, and the degreaser is by dication surface
Activating agent, activated silica, sodium carboxymethylcellulose and water compound.The dication surfactant is that one kind has
The symmetrical molecule of Long carbon chain alkyl, bis-quaternary ammonium salt cationic polar group, molecular formula are as follows:
The component that the degreaser respectively forms is as follows:
Preferably, the component that the degreaser respectively forms is as follows:
Another object of the present invention discloses a kind of preparation method of the heavy crude heat extraction sewage degreaser of resisting high temperature, high salt,
Specific step is as follows:
(1) in 30~50 DEG C of thermostat water baths, 10-30 parts of water is placed in a beaker, stirring rate 300~
Under 400rpm, it is slowly added to 1 part of dication surfactant, after being added completely into, continues 20~30min of stirring, must mix
Solution；
(2) temperature of above-mentioned mixed solution is adjusted to 50~55 DEG C, after temperature is constant, stirring rate be 200~
Under 250rpm, it is slowly added to 0.01~0.75 part of sodium carboxymethylcellulose, continues 20~30min of stirring, obtains clear solution；
(3) temperature of above-mentioned clear solution is adjusted to 35~40 DEG C, stirring rate is adjusted to 400~600rpm, constant temperature 10
After~15min, it is slowly added to 0.1~1.5 part of activated silica, constant temperature stirs 20~25min, is then cooled to 20~25 DEG C,
Continue 10~30min of stirring, Temperature fall finally obtains degreaser of the invention.
A kind of degreaser for heavy crude heat extraction sewage processing, as follows using technical process:
According to the oil-containing situation in oil-field thick-oil thermal recovery sewage, degreaser of the invention is added into sewage, realizes grease
Separation is further processed after recycling petroleum substance for subsequent technique.The specific additional amount of degreaser is as follows:
(1) when oil-containing β >=500mg/L, degreaser, which is added, makes 60~80mg/L of mass concentration of degreaser in sewage；
When (2) 500 > oil-containing β >=300mg/L, be added degreaser make the mass concentration 30 of degreaser in sewage~
50mg/L；
When (3) 300 > oil-containing β >=100mg/L, be added degreaser make the mass concentration 20 of degreaser in sewage~
30mg/L；
(4) when oil-containing β < 100mg/L, degreaser, which is added, makes 0.1~10mg/L of mass concentration of degreaser in sewage.
Heavy crude heat extraction sewage degreaser provided by the invention, the dication surfactant in degreaser, contained by
Hydrophobic grouping it is longer, easily enter in micella, can more reduce its surface Gibbs can, it is smaller so as to cause critical micelle concentration,
I.e. dosage is less；Hydrophobic grouping, that is, lipophilic group can be adsorbed onto rapidly greasy surfaces, subsequent dication quaternary ammonium salt group insertion
To inside greasy dirt, cotton-shaped particle is formed, to achieve the purpose that oil removing；Sodium carboxymethylcellulose is water soluble polymer polymerization
Object, it can make the neutralization of bridge formation or charge between particle by the solid and semisolid ion in absorption water, to promote double sun
The flocculation of ionic surface active agent, moreover, sodium carboxymethylcellulose also have intermolecular " winding " package action,
Dewatering might as well；Activated silica belongs to inorganic compound, and it is good which has the characteristics that heat resistance, moreover, temperature is higher,
Its activity is higher, adaptable strong, the good feature of performance.
The present invention is had the following advantages and beneficial effects: compared with prior art
(1) raw material sources of degreaser of the invention are extensive, and synthesis technology is simple；
(2) degreaser temperature-resistant anti-salt performance of the invention is good, and resistance to salinity reaches 250000mg/L, 250 DEG C of heatproof, overcomes
The disadvantage of previous degreaser temperature-resistant anti-salt performance difference；
(3) degreaser of the invention has the characteristics that oil removal efficiency is high, the oil removal rate of heavy crude heat extraction sewage up to 96% or more,
More existing medicament improves 40% or more, meets the pretreated requirement of oil removing of heavy crude heat extraction sewage.
