Description
Technical field
The invention belongs to the preparing technical field of chemical products, relate to one and be applicable to sump oil process
Environment-friendly type waste oil treatment agent.
Background technology
Substantial amounts of sump oil can be produced during oil exploitation and production, leak outside including oil well pipe
And ground crude oil, sewage precipitation tank, oil removing pot, floatation cell recovered oil, free water knockout (FWKO) and
Electric dehydrator processes abnormal conditions and enters the sump oil etc. of emergency storage tank, if these sump oils are directly arranged
It is put in surrounding environment, the energy can be wasted and pollute environment.The composition of oilfield sump oil is extremely complex,
In it, water content is usually above 10%, and containing heavy constituents such as higher colloid, asphalitine and solid
Body impurity, possibly together with a large amount of demulsifiers added in process of production, flocculant, bactericide,
The composition such as corrosion inhibiter, antisludging agent, causes sump oil intractability and cost the biggest.
In recent years, along with country's pay attention to day by day to efforts at environmental protection, oil recovery process is wanted
Asking stricter, the most efficient, the economic sump oil that processes has become what oil field faced
Severe challenge.Oil recovery method the most commonly used in the art mainly has centrifugal process, hydrothermal solution to wash
Method, microbial method etc..It is relatively big that centrifugal process processes sump oil amount, is suitable for High water cut sump oil, but sets
Standby fluctuation of service, easily shuts down；The mud that hydrothermal solution washing method processes is neutrality, it is simple to give birth to
Change final process, and be beneficial to industrialize implementation, but but need to be continuously replenished clear water, water consumption
Amount is big；Though microorganism treatment environmental protection is easy, but the time of process is long, produces effects slow.At home,
The most a lot of oil fields generally the most directly process sump oil, but will in the way of discarded object
Oil recovery company sold to by oil-containing sump oil, at the substantial amounts of sump oil of recovery company to be paid
Reason is taken and freight, also results in substantial amounts of crude oil and cannot reclaim secondary use.
Summary of the invention
The problem that it is an object of the invention to there is prior art is solved, it is provided that at Yi Zhong
Manage effective, preparation is simple, the environment-friendly type waste oil treatment agent of low cost, this waste oil treatment agent
Substantial amounts of crude oil can not only be reclaimed, improve yield, and can effectively eliminate sump oil to environment
Pollute, save control expense.
The technical solution used for achieving the above object is such that being provided
Environment-friendly type waste oil treatment agent is blended with machinery by surfactant, flocculant and three kinds of components of solvent
The preparation of the uniform mixed preparing of mode, the mass percent of three kinds of components is:
Surfactant 25%～50%,
Flocculant 5%～10%,
Solvent 40%～70%；
Described surfactant be cationic surfactant and/or anion surfactant and/
Or nonionic surfactant and/or amphoteric surfactant, described flocculant is polymerised sulphur
One in acid iron, PAFS, aluminium polychloride, aluminum sulfate, described solvent is
One or several in methyl alcohol, ethanol, ethylene glycol, propane diols, glycerine, ethylene glycol monobutyl ether
Planting the mixture with distilled water, wherein distilled water accounts for the 40%～80% of solvent quality.
The further technical solution of the present invention also resides in, and cationic surfactant is C12-18
Dimethyl benzyl ammonium chloride or C12-18Trimethyl ammonium chloride, anion surfactant is dodecane
Base benzene sulfonic acid acid sodium, DBSA, nonionic surfactant is polyoxyethylene nonyl phenyl second
Alkene ether and/or polyethers and/or organic silicon surfactant and/or tween, amphoteric surfactant
One for alkyl betaine.
In actual contents prescription, the cationic surfactant in surfactant is myristyl
Dimethyl benzyl ammonium chloride, anion surfactant is DBSA acid sodium, non-from
Sub-surface activating agent is OP-10 and/or Tween-60 and/or Tween-80, and amphoteric surface lives
Property agent is empgen BB.
The invention has the beneficial effects as follows: this environment-friendly type waste oil treatment agent formula uses kinds of surface
Activating agent compounds, and oil droplet surface can be played electrostatic neutralization, the oil droplet phase after being neutralized
Electrostatic repulsion between Hu reduces, and collision probability increases, and makes the bad stability of emulsion, reaches
To breakdown of emulsion, the purpose of water-oil separating；The effect of flocculant can produce electrochemical reaction, plays de-
Except fine impurities and silt particle and the effect of breakdown of emulsion, and then improve oil removal efficiency.This waste oil treatment agent
Dewatering efficiency is high, is increased without equipment, simple possible, can effectively isolate former from sump oil
Oil (crude oil recovery rate can reach 30%～50%), obtains good economic benefits, and can eliminate dirt
The oil pollution to environment, saves control expense, thus utilizing this waste oil treatment agent scrubbing is oil field
A kind of effective ways of sump oil minimizing.
