Description
Technical field
The present invention relates to a kind of sludge dispersant and preparation method thereof, more particularly to a kind of oil-sludge treatment dispersant and its
Preparation method.
Background technology
Greasy dirt is primarily referred to as the oily sludge due to the ground crude oil that a variety of causes is caused and soil formation, and oil field
The oil-containing mud sand that system is discharged in normal production, is a kind of solid waste rich in mineral oil, main component be crude oil, mud and
Water.The bed mud refinery that Sludge in Oilfields main source has block station, the oil tank of multi-purpose station, settling tank, Water Tank, oil interceptor contains
Oil-sand, greasy filth drilling well, operation, conduit wiring piercing that oily sewage disposal facility, lighter hydrocarbons processing factory purifying device for natural gas are cleared out
And the ground crude oil and oily sludge produced.Its is bulky, is one of important pollutant for producing in oilfield development process.Through
Investigation, each block station of Shengli Oil Field, multi-purpose station clear up oily sludge amount about at 150,000 tons or so every year, add ground crude oil recovery
Remaining greasy filth, full oil field at least produce ten thousand tons of greasy filth every year afterwards.Current oil field development is own to enter High water cut, high recovery ratio and height
Containing husky situation, to keep stable yields to increase production, extraction liquid measure must be increased, cause greasy filth yield further to increase.Thus may be used
See, the processing to oil field sludge has been to be become in the epoch.
Because the property of oily sludge is special, its dehydration and treatment technology difficulty are big, cost is high, are always puzzlement oil row
The difficult problem of environmental protection of industry.Gradual perfection and the requirement of technological progress in enterprises with environmental regulation, the pollution control skill of oily sludge
Art has increasingly caused the concern and attention of people, since over half a century, and the treatment technology of oily sludge have developed rapidly, processing side
Method is broadly divided into mechanically decoupled, solvent extraction, biological treatment and heat treatment etc..But every kind of method has respective advantage and disadvantage
With use scope.For example, although mechanically decoupled removing oil is simple to operate, be easily achieved, treatment effect is not good；Though capacity extraction
Higher oil removal rate is so shown, but needs higher concentration and treatment temperature, this can make You Heshui dissolve each other, in emulsified state,
The recovery of crude oil is not easy to, extractant biological degradability is poor, with certain toxicity, has severely impacted Environment-Ecosystem；
Biological treatment effect is poor, the cycle is long；Heat treatment power consumption is big, equipment investment is higher；It is sustainable in order to ensure environment for human survival
Development, it is imperative to the free of contamination disposal of oily sludge medicament of ecological environment to develop.
The content of the invention
The present invention provides a kind of new sludge dispersant and preparation method thereof to make up the deficiency in prior art.The greasy filth
Dispersant effect is good, with efficient, low consumption, convenient, nonhazardous, several big features such as be widely used.The technical side of the present invention
Case is：
A kind of disposal of oily sludge dispersant, includes each component of following parts by weight, nonionic surfactant 1.2-5.6
Part, 5-10 parts of sodium tripolyphosphate, 1.5-5.2 parts of inorganic salts, 5.8-10 parts of diethylene glycol monobutyl ether, 69.2-86.5 parts of water.
Described nonionic surfactant is sorbierite esters nonionic surfactant, and its composition is sorbitol anhydride list
Laurate.
Described inorganic salts are the one or more in sodium chloride, potassium chloride, sodium sulphate or potassium sulfate according to arbitrary proportion
Mix.
The preparation method of oily sludge dispersant, comprises the following steps：By nonionic surfactant, sodium tripolyphosphate,
Inorganic salts, diethylene glycol monobutyl ether are proportionally well mixed in normal temperature, obtain sludge dispersant；Wherein incorporation time is 30-
40 minutes.
It is each that sludge dispersant is produced during oil exploitation, defeated collection, oil product refining processing and disposing polluted water in oil
Plant the application in the processing of oily sludge.
The detailed process that sludge dispersant is applied to oil-sludge treatment is as follows：Greasy filth is mixed in blending tank with water first
It is even, sludge dispersant is then added, is stirred, the product after disperseing carries out point of oil, water, mud in oil-sludge separation device
From；Whipping temp is 30-45 DEG C, and mixing time is 60-120 minutes.
The mass ratio of greasy filth and water is 1: 3-1: 5, and the addition of sludge dispersant accounts for the mass percent of greasy filth for 1%-
5%.
Inventive dispersant has the following advantages compared with traditional dispersant：
(1) sludge dispersant dispersion effect of the present invention is good, and oil recovery rate is high, is particularly suitable for use in the high greasy filth of oil content；
(2) sludge dispersant biological degradability of the present invention is good, nontoxic harm, environmental protection；
(3) sludge dispersant of the present invention, preparation method is easy, applied widely, it is easy to commercial Application.
Embodiment
The invention will now be further described with reference to specific embodiments, advantages of the present invention and feature will be with description and
It is apparent.But these embodiments are only exemplary, do not constitute any limitation to the scope of the present invention.People in the art
