Abstract
The invention relates to a water purification agent, in particular to an oily sewage purificant used for treating oily sewage in oil fields, which consists of the following components according to weight percentage: 30 to 40 percent of aluminum chloride hexahydrate, 10 to 25 percent of epoxypropyl polyquaternary amine and 35 to 50 percent of poly(diallyldimethylammonium chloride. The oily sewage purificant is mainly used for the emulsion breaking and oil removing of oily sewage emulsion liquid or other 0/W sewage, has enough strong electrophilicity to neutralize negative charge formed by an emulsifier, has enough strong flocculation capability to flocculate particles in the emulsion liquid for facilitating the formation of large vanadium flowers, and has enough strong surface activity to break the interfacial energy of the emulsion liquid. The purificant is characterized by high deoiling rate, limpid water of dehydration, quick floating upwards of oil clots and even oil-water boundary. In addition, the purificant has the advantages of low dosage, low cost and broad application prospect.
Description
Technical field
The present invention relates to a kind of water purification reagent, specifically a kind of purificant for purifying oily sewage that is used for disposing polluted water in oil.
Background technology
The oily(waste)water milk sap in oil field mainly contains that crude oil emblem grain, machine are assorted, stratum small bits of clay and a spot of emulsion splitter constitute, these particulates are under the effect of comparatively high temps, transmission by the pipe pump has formed more stable water external emulsion, reason is electrocharge effect, it is the existence of the finely divided oily strain surface negative charge of oily(waste)water, produce the electrostatic double layer phenomenon and be adsorbed with firm hydration shell, caused elaioleucite contact and gathering each other.Like this. oil-in-water emulsion is by some emulsifier, makes maximum system energy maintain minimum level and keeps stable, and its milk sap degree of stability forms the very big relation that how much has of emulsion fraction of particle with it.Generally speaking, the emulsifying agent fraction of particle is high more, and the milk sap of formation is stable more, so reduce the emulsifying agent fraction of particle is the important factor of handling oily(waste)water, after the big sewage discharge of this oleaginousness, pollute and serious, cause for corresponding current and have a strong impact on.
Summary of the invention
The present invention be directed to the pollution problem of a large amount of oily(waste)waters of present oil field discharging, a kind of breakdown of emulsion de-oiling, de-oiling rate height that is mainly used in oily(waste)water milk sap and other 0/W sewage is provided, deviates from that water is clear, fast, the neat purificant for purifying oily sewage of water-oil interface of oil clot come-up.
Realize the foregoing invention purpose by the following technical solutions: a kind of purificant for purifying oily sewage, the mass percent of its moiety and each composition is: six hydration aluminum chlorides 30～40%, epoxypropyl is gathered quaternary amine 10～25%, Poly Dimethyl Diallyl Ammonium Chloride 35～50%.
This purificant for purifying oily sewage is mainly used in the breakdown of emulsion de-oiling of oily(waste)water milk sap and other 0/W sewage, has very strong close electric charge ability, is enough to the negative charge that the balance emulsifying agent forms; Very strong flocculation ability is also arranged, can flocculate the milk sap particulate and be convenient to form big vanadium flower; Characteristics such as very strong surfactivity is also arranged, can destroy the interfacial energy of milk sap, can realize de-oiling rate height, it is clear to deviate from water, and the oil clot come-up is fast, and water-oil interface are neat, and consumption is few, and cost is low, has a extensive future.
Embodiment
Below in conjunction with embodiment in detail the present invention is described in detail.
Embodiment one:
| Title | Six hydration aluminum chlorides | Epoxypropyl is gathered quaternary amine | Poly Dimethyl Diallyl Ammonium Chloride |
| Proportioning | 40 | 15 | 45 |
Each moiety in this form is mixed and can use according to the mass percent in its proportioning.
Embodiment two:
| Title | Six hydration aluminum chlorides | Epoxypropyl is gathered quaternary amine | Poly Dimethyl Diallyl Ammonium Chloride |
| Proportioning | 35 | 25 | 40 |
Each moiety in this form is mixed and can use according to the mass percent in its proportioning.
Epoxypropyl described in the present invention is gathered quaternary amine, and its chemical ingredients is poly-epoxypropyl alkyl dimethyl ammonium chloride, is the product that is generated by epoxy chloropropane and dimethylamine reaction.
After in the oily(waste)water that the oil field gives off, adding this scavenging agent, cation type polymer can adsorb the oil-containing particulate in water, the o/w emulsion that the neutralization surface is electronegative, in playing and electric charge, destroy the water-oil interface layer, produce bridging and throwing out, form the big oil droplet of particle diameter, under the buoyancy of water effect, from water, separate gradually, thereby reach the water purifying purpose.
Claims (1)
1, a kind of purificant for purifying oily sewage is characterized in that, the mass percent of its moiety and each composition is: six hydration aluminum chlorides 30～40%, epoxypropyl is gathered quaternary amine 10～25%, Poly Dimethyl Diallyl Ammonium Chloride 35～50%.
