Embodiment 1

[0008]

[0009] The components in the table can be used after being evenly mixed according to their mass percentages in the proportioning ratio.

Embodiment 2

[0012] The components in the table can be used after being evenly mixed according to their mass percentages in the proportioning ratio.

[0013] The glycidyl polyquaternary amine described in the present invention has a chemical composition of polyglycidyl dimethyl ammonium chloride, which is a product generated by the reaction of epichlorohydrin and dimethylamine.

[0014] After the purifier is added to the oily sewage discharged from the oil field, the cationic polymer can absorb oily particles in the water, neutralize the negatively charged o / w emulsion on the surface, neutralize the charge, destroy the oil-water interface layer, and produce Bridging and flocculation will form oil droplets with large particle size, which will be gradually separated from the water under the buoyancy of water, so as to achieve the purpose of water purification.

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 [0001] The invention relates to a water purifying agent, in particular to an oily sewage purifying agent used for oilfield sewage treatment. Background technique [0002] The oily sewage emulsion in the oil field is mainly composed of crude oil particles, organic impurities, formation clay particles and a small amount of demulsifier. These particles form a relatively stable oil-in-water emulsion through the transmission of the tube pump under the action of high temperature. The reason lies in the charge effect, that is, the existence of negative charges on the surface of finely dispersed oil plants in oily sewage produces an electric double layer phenomenon and adsorbs a firm hydration film, resulting in the contact and aggregation of oil particles. In this way, the oil-in-water emulsion uses some emulsifiers to keep the energy of the system at the lowest level and maintain stability. The stability of the emulsion has a great relationship with the amount of p...
