Abstract
The invention relates to the technical field of oil-field water treatment chemical, particularly to a special flocculant for oily wastewater and a manufacturing method for the same. The special flocculant comprises the following ingredients in parts by weight: 5-8 parts of polydimethyldiallylammonium chloride, 1-5 parts of polyacrylamide (APAM), 10-30 parts of aluminium polychlorid and 70-80 parts of distilled water. The special flocculant is strong in flocculation capacity, capable of rapidly demulsifying, fast in sedimentation speed and small in the volume of flocculating body, as well as is a novel flocculant effective in both alkaline condition and neutral condition.
Description
Technical field
The present invention relates to oil field water treatment agent technical field, special-purpose flocculation agent of especially a kind of oily(waste)water and method of manufacture thereof.
Background technology
In the oilfield exploitation, primary oil recovery is a power by natural energy; Secondary oil recovery keeps reservoir pressure with the man-made injection mode; TOR is to improve tar productivity through changing the characteristic of injecting water.Secondary, TOR are mainly carried out in the oil field at present.Every production 1t crude oil needs water filling 2 3t approximately, and the extraction water content in crude oil constantly rises, and water ratio is generally up to 70%～95%.Therefore produce a large amount of oily(waste)waters; The waste water complicated component; Except natural impurity such as the oil in water emulsion that contains solubility salt and heavy metal, suspension, solid particulate, hydrogen sulfide; Also contain the chemicaladditives that some are used for changing recovered water character, and the acids that injects the stratum, oxygen scavenger, lubricant, sterilant, scale inhibitor etc.It directly is used for re-injection causes reservoir choke easily, quicken pipeline corrosion, efflux and pollute, therefore must could re-injection or discharging through strict the processing.The most of refinery of China uses and gathers sulphur aluminum chloride (PACS) as the agent of oily(waste)water flocculation treatment, and its main drawback is that the settling of floccus speed that forms is slow, in low temperature, low-cloudy water flocculation treatment, is prone to cause " race sail " phenomenon; Treatment effect is undesirable; And can bring secondary pollution to environment, foulings such as turnover pipeline, molten cylinder are serious, are difficult to remove.Bodied ferric sulfate (PFS) has characteristics such as flocculation ability is strong, alumen ustum is big, sedimentation is fast, and is applied widely, but also has avoided secondary pollution.But, use popularization difficult in the oil field because of complex manufacturing, cost height and the residual colourity in water.
Summary of the invention
The object of the present invention is to provide special-purpose flocculation agent of a kind of oily(waste)water and method of manufacture thereof; It mainly solves above-mentioned existing in prior technology defective; This special use flocculation agent have flocculation ability strong, can fast emulsion breaking, settling velocity is fast, the flocs unit volume is little, it is effective a kind of novel flocculant equally under alkalescence and neutrallty condition.
For realizing above-mentioned purpose, the present invention realizes like this.
The special-purpose flocculation agent of a kind of oily(waste)water, it is characterized in that: it is 5～8 parts of Poly Dimethyl Diallyl Ammonium Chlorides according to the composition of parts by weight, 1～5 part of SEPIGEL 305 (APAM), 10～30 parts of Poly aluminum Chloride (PAC)s, 70～80 parts of zero(ppm) water.
The method of manufacture of the special-purpose flocculation agent of a kind of aforesaid oily(waste)water is characterized in that: A, Poly Dimethyl Diallyl Ammonium Chloride is dissolved in 10 parts the zero(ppm) water and do not stop to stir, and subsequent use; B, SEPIGEL 305 is dissolved in 10 parts the zero(ppm) water and do not stop to stir, subsequent use; C, will remain zero(ppm) water and add in the reaction vessel; And stir; And then Poly aluminum Chloride (PAC) is added in the reaction vessel; Continuation is stirred, and will dissolve good Poly Dimethyl Diallyl Ammonium Chloride, polyacrylamide solution after 30 minutes and add in the reaction vessel, stirs after 1 hour to get product again.
The advantage that prescription of the present invention and method can embody is:
1, the Poly Dimethyl Diallyl Ammonium Chloride that uses in the special-purpose flocculation agent of the disclosed a kind of oily(waste)water of the present invention is a kind of strong cation polyelectrolyte; Have very strong breakdown of emulsion flocculation ability to containing oil-in-water emulsion in the sewage in a large number, also have very strong water separation capability simultaneously;
2, the SEPIGEL 305 (APAM) that uses in the special-purpose flocculation agent of the disclosed a kind of oily(waste)water of the present invention is for suspended particle; Thick, high, the particle band positive charge of concentration, water Ph value are neutral or alkaline sewage, owing to contain the solids that suspend in a certain amount of polar group ability planar water in the SEPIGEL 305 molecular chain; Making builds bridge between particle forms big throw out; Therefore it quickens the sedimentation of the particle in the suspension-s, and the clarification of very significantly accelerating solution is arranged, and promotes effects such as filtration.
2, it is big that the Poly aluminum Chloride (PAC) that uses in the special-purpose flocculation agent of the disclosed a kind of oily(waste)water of the present invention has a molecular structure, the characteristics of high adsorption capacity, and solvability is good in water, and active high, the alumen ustum that cohesion forms in water body is big, and sedimentation is fast, more must be in flocculating effect.
3,, especially in the oil field waste treating processes, use the special-purpose flocculation agent of oily(waste)water provided by the invention to have the breakdown of emulsion ability at oily(waste)water; And can precipitate by rapid flocculation, the flocculation particle is big and tight, and the flocculation quantity of slag is few; Be convenient to filtering separation; Water quality treatment is limpid, and each item index reaches secondary water filling and direct emission request, and cost is lower.
Embodiment
Embodiment 1:A, 5 parts of Poly Dimethyl Diallyl Ammonium Chlorides are dissolved in 10 parts the zero(ppm) water and do not stop to stir, subsequent use; B, 1 part of SEPIGEL 305 is dissolved in 10 parts the zero(ppm) water and do not stop to stir, subsequent use; C, 50 parts of zero(ppm) water are added in the reaction vessels; And stir; And then 10 parts of Poly aluminum Chloride (PAC)s are added in the reaction vessel; Continuation is stirred, and will dissolve good Poly Dimethyl Diallyl Ammonium Chloride, polyacrylamide solution after 30 minutes and add in the reaction vessel, stirs after 1 hour to get product again.
