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 temperature-resistant high-efficient oily wastewater removes
Finish and preparation method thereof.
Background technique
With the fast development of petroleum industry, the oilfield sewage of generation is more and more, how to handle such sewage gradually at
For the serious problem that oil play faces, for example unprocessed direct emission of these oily wastewaters will seriously pollute environment, while pole
Big waste water resource.To efficiently use oilfield produced waste water, need to be effectively treated sewage.
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.
Patent ZL201410254042.8 " a kind of composite flocculation deoiling agent for oily waste water treatment " uses sulfuric acid
Aluminium, magnesium chloride, magnesium hydroxide, bentonite and polyacrylamide are combined, which has dosage few, and oil removal efficiency is high,
The features such as preparation is simple, at low cost, but degreaser needs are used with corrosive magnesium hydroxide, the compound is to equipment
With stronger corrosiveness.
Summary of the invention
The present invention for currently available technology deficiency and a kind of temperature-resistant high-efficient oily wastewater degreaser and its preparation are provided
Method, the degreaser have simple process, low in cost, adaptable, and the feature that heat resistance is strong and deoiling effect is good, most
High-temperature resistant is up to 250 DEG C, and for the oil removal rate of oily wastewater up to 97% or more, more existing medicament improves 50% or more.
The purpose of the present invention is to provide a kind of temperature-resistant high-efficient oily wastewater degreaser, which is by perfluoro triethylamine
Cationic degreaser is generated with 3- dodecyl -5- octyl benzyl bromine reaction in ethanol solution, molecular formula is as follows:

For 1:1.1.
It is another object of the present invention to provide a kind of preparation method of temperature-resistant high-efficient oily wastewater degreaser, the oil removings
The preparation method of agent specifically includes the following steps:
(1) perfluoro triethylamine of aforementioned proportion is added in ethanol, is stirred at being 40~60 DEG C in temperature, stirring rate is
250~350rpm persistently stirs 5~10min, catalyst sulfuric acid dimethyl ester is then slowly added dropwise, after the completion of catalyst addition,
It is cooled to room temperature, obtains solution A；
(2) the 3- dodecyl -5- octyl benzyl bromide of aforementioned proportion is added in solution A, it is to slowly warm up to 80~
85 DEG C, stirring rate is 450~500rpm, reacts 8~12h, is then cooled to 50~60 DEG C, reacts 2~2.5h, reaction time
After stop stirring, Temperature fall obtains crude product in solution B；
(3) above-mentioned crude product in solution B is boiled off into etoh solvent, residue is washed with the sodium hydroxide that mass concentration is 10%
Three times, 24~48h is then dried in a vacuum drying oven, obtains final product degreaser of the invention.
Wherein, the ethanol consumption is 5~15 times of perfluoro triethylamine quality；The catalyst sulfuric acid dimethyl ester
Dosage is the 0.1~0.5% of perfluoro triethylamine quality.
The reaction equation is as follows:
A kind of degreaser of oily wastewater, as follows using technical process:
According to the oil-containing situation in oil-contaminated water of oil field, degreaser of the invention is added into sewage, realizes demulsification and oil
Water separation is further processed after recycling petroleum substance for subsequent technique.The specific additional amount of degreaser is as follows:
(1) when oil-containing α >=800mg/L, degreaser, which is added, makes 80~200mg/L of mass concentration of degreaser in sewage；
When (2) 800 ﹥ oil-containing α >=500mg/L, degreaser, which is added, makes 50~80mg/ of mass concentration of degreaser in sewage
L；
When (3) 500 ﹥ oil-containing α >=200mg/L, degreaser, which is added, makes 20~50mg/ of mass concentration of degreaser in sewage
L；
(4) when oil-containing α < 200mg/L, degreaser, which is added, makes 0.5~20mg/L of mass concentration of degreaser in sewage.
The degreaser of oily wastewater provided by the invention, belongs to cationic surface active agent, which has fluorine-containing sun
Ionic group, with lower critical micelle concentration, reaches identical table compared with not fluorine-containing cationic surfactant
The amount for the surfactant that face tension needs is less, meanwhile, which has better wetability and lipophilicity, in dirt
The floccule relatively stable with greasy dirt energy performance in water.Moreover, fluorine-containing surfactant also has high heat resistance stability
And high chemical stability, the oil removal treatment suitable for high-temperature oil reservoir recovered water.Oily wastewater oil removing agent molecule provided by the invention
In contain C12And C8Two kinds of hydrophobic groupings can play the role of flocculated in conjunction with the greasy dirt of different component.
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, adaptable, and dosage is few, can meet ring
The needs of border protection and oil field development；
(2) degreaser of the invention has stronger heat resistance, and highest heatproof is up to 250 DEG C；
(3) degreaser of the invention has the characteristics that oil removal efficiency is high, and the oil removal rate of oily wastewater is more existing up to 97% or more
Some medicaments improve 50% or more, meet the pretreated requirement of oil removing of oily wastewater.
