Description
Technical field
The present invention relates to oilfield chemical technical field, concrete open a kind of disposal of oily sludge with environment-friendly type dispersant and
Preparation method.
Background technology
Oil exploitation, collect defeated, refining and oily waste water treatment during all to produce the black of a large amount of oil-containing solid
Body, semisolid waste, i.e. oily sludge, be called for short greasy filth, and its main component is oil, Ni Heshui.Solid particle chi in greasy filth
Very little can be from not enough micron to several inches, great majority are between 1 to 100 micron, and oil composition depends on that crude oil kind, oil plant are tied
Structure and operating condition, the composition of mud may change over and change.Preliminary survey shows, the annual oily sludge of China increases newly
Yield reaches about 800,000 tons, owing to containing water, silt, sulfide, benzene homologues, phenols, hydro carbons etc., not only land occupation in greasy filth
And space, and severe contamination air, soil and groundwater, constrain the development that oil field at home produces to a certain extent.Mesh
Before, oily sludge is classified as dangerous solid waste (HW08) by country, it can be seen that, when to the process of oil field sludge being
In generation, is become.
At present both at home and abroad conventional oily sludge medicament processing method is broadly divided into: surfactant eluting oil removing, broken
Compounding oil removing between Emulsion breaking milk and removing oil, soda lye wash oil removing, flocculant flocculation deoiling, various medicament.Five kinds of methods are necessarily
Oily sludge can be obtained preferable treatment effect in degree, but every kind of method has respective pluses and minuses and range.
Such as, although surfactant eluting oil removing shows higher oil removal rate, but higher concentration and treatment temperature, this meeting are needed
Make You Heshui dissolve each other, in emulsified state, be not easy to former oil recovery；And biological degradability is poor, there is certain toxicity, seriously
Have impact on Environment-Ecosystem.In order to ensure the sustainable development of environment for human survival, exploitation contains ecological environment is free of contamination
Greasy dirt treatment agent is imperative.
Summary of the invention
It is an object of the invention to provide a kind of disposal of oily sludge environment-friendly type dispersant and preparation method thereof, this greasy filth divides
Powder dispersion effect is good, oil recovery rate is high, production cost is low, environmental protection, and preparation method is easy, applied range.
To achieve these goals, present invention employs following technical scheme: its raw material contains such as by mass percentage
Lower component: cationic surfactant 5wt%-20wt%, silicate 5wt%-33wt%, inorganic salt 1.5wt%-10wt%,
Water 37wt%-88.5wt%, the most each constituent content sum is 100wt%；Method comprises the steps: described cation form
Face activating agent, silicate, inorganic salt and water mix homogeneously, obtain sludge dispersant.
Wherein, described cationic active agent is a cationoid polymeric surfactant, and its Main Ingredients and Appearance is phenol
Amine aldehyde resin polyoxyethylene polyoxypropylene ether.
Wherein, described silicate is mainly derived from sodium silicate or the sodium silicate solution of solid powdery.
Wherein, described inorganic salt is one or more in sodium chloride, potassium chloride, sodium sulfate or potassium sulfate.
Preferably, by cationic surfactant, silicate, inorganic salt and water mix homogeneously in certain proportion, obtain
Sludge dispersant；Wherein incorporation time is 30-60 minute, and mixing temperature is 50-90 DEG C.
Wherein, greasy filth is mixed homogeneously with water in blending tank, be subsequently adding sludge dispersant, be stirred, after dispersion
Product in oil-sludge separation device, carry out the separation of oil, water, mud.
Preferably, described greasy filth is 1: 3-1: 5 with the mass ratio of water, and the addition of sludge dispersant accounts for the quality hundred of greasy filth
Proportion by subtraction is 1%-6%；Whipping temp is 70-90 DEG C, and mixing time is 60-120 minute.
The beneficial effects of the present invention is: use that above-mentioned dispersant is effective, biological degradability good, oil recovery rate
Height, is particularly well-suited to the high greasy filth of oil content and the impact on environment is little, environmental protection, and production cost is low, and preparation method is easy,
Applied widely, there is bigger industrial applications prospect.
