Description
Technical field
The present invention relates to a kind of surfactants compounded with several raw materials, can reduce the surface of tar heavy oil in oil sludge and sand
Tension makes its oil content reach the emission request of environmental legislation for the washing of oil sludge and sand.
Technical background
Oil sludge and sand is the oily solid sludge generated during oil exploitation, transport, refining and oily waste water treatment.Oil
Containing poisonous and harmful substances such as a large amount of benzene homologues, phenols, anthracene, pyrene, Polychlorinated biphenyls, pathogen, heavy metals in silt particle, if improper
Reason direct emission is conducted oneself well, not only occupies a large amount of arable lands, and will all pollute to Soil Surrounding, water body, air.Greasy filth at present
Sand is classified as hazardous waste by country.
In numerous greasy filth sand processing techniques and method, the reality of chemico-heating wash multi-stage separation treatment technique at home and abroad
It is widely used in engineering.The surface tension that tar heavy oil in oil sludge and sand is wherein reduced using surfactant, makes oil enter water phase, from
And achieve the purpose that cleaning mud oil sand.
Currently used surfactant has anionic surfactant, such as neopelex (LAS), dodecane
Base sodium sulphate (SDS), nonionic surfactant such as TX-100, Brij35 and cleaning additive sodium metasilicate etc..They wash greasy filth
The significant effect of comparison is washed, but highest commonly reaches 76.9% oily removal rate, has tended not to meet current environment department
Emission request about domestic oil-containing mud sand.So the washing oil silt particle surfactant that development cost is low, effect is good is very must
It wants.
Summary of the invention
Cardinal principle of the invention is based on the methyl-prop with the side-chain of polyelycol result that terminal substituent is methyl
Olefin(e) acid based compound has emulsification function as the polymer of monomer, develops Novel polymer emulsifier.This macromolecule latex
Agent is formed by New-type emulsifier with addition of certain oil components and surfactant, can reduce rapidly the weight in oil sludge and sand
The surface tension of tar, it is good with the wellability of water, achieve the effect that get along swimmingly with each other, to play petroleum in elution oil sludge and sand
Purpose.
Main composition of the invention is as follows:
1) a kind of macromolecule emulsifier, containing methoxy poly (ethylene glycol) poly-methyl acrylate, molecular weight is arrived 1000
Between 100000.
2) a kind of oil components are selected from one or more of alkyl glycerylether, linoleic acid, Sensiva SC50.
3) mass ratio of macromolecule emulsifier and oil components is 1: 1 to 1: 50.
4) a kind of surfactant, neopelex, lauryl sodium sulfate (SDS) or biosurfactant
One or two.The 1-20% of shared macromolecule emulsifier and oil components gross mass.
Technology of the invention is described further below.
Composite high-molecular emulsifier molecular weight with higher of the invention, with the molecular weight in the tar heavy oil in oil sludge and sand
Quite, according to the principle of " phase patibhaga-nimitta melts " in chemistry, macromolecule emulsifier can be fused together well with tar heavy oil.But tar
Under solid state, emulsifier is difficult to infiltrate wherein, so needing the chemically active surface group of oil components and surfactant
As the transition bridge of two kinds of molecule contacts blending, the surface tension of tar is reduced, micellar solution is formed, emulsifies hydro carbons.Separately
Outer surfactant can also be such that water mutually infiltrates with tar, achieve the effect that elution.
Above-mentioned composite emulsifier ingredient has raw material sources wide, and cheap, the stable advantage of performance, being can be in oil
Widely applied product in the Practical Project of silt particle washing.
Specific embodiment
Methoxy poly (ethylene glycol) poly-methyl acrylate: 10 grams, saliva happy together safe chemical products Co., Ltd in Beijing's produces.
Linoleic acid: 20 grams, Anqing Zhongchuang Bioengineering Co., Ltd. produces
Surfactant: neopelex, 5 grams, Wujiang Wei Tong Chemical Co., Ltd. produces.
Oil sludge and sand: Gudao area of Shengli Oilfield oil recovery factory oil sludge and sand.
Prepare embodiment 1:
By 10 grams of methoxy poly (ethylene glycol) poly-methyl acrylates, 20 grams of linoleic acid and 5 grams of poly- first of methoxy poly (ethylene glycol)
Base acrylate pours into beaker, and a small amount of water is added, and is heated to 40 degrees Celsius, stirs ten minutes, obtains emulsifier finished product after cooling.
Application Example 2:
300 grams of oil sludge and sands are poured into sky beaker, emulsifier made from 3 grams of addition adds 600 milliliters of water, stirs and heat
To 70 degrees Celsius, continue half an hour, then static 20 minutes, it is seen that silt in the bottom, water in middle level, oil float upper layer,
Realize mud grease three phase separation.
TPH content before and after analysis washing oil silt particle obtains following result:
Claims (4)
1. a kind of macromolecule emulsifier, containing methoxy poly (ethylene glycol) poly-methyl acrylate, molecular weight is 1000 to 100000
Between.
