Description
Technical field
The present invention relates to demulsifier technical fields more particularly to a kind of greasy filth demulsifier and its preparation method and application.
Background technique
In the exploitation of petroleum, collect the black solid that a large amount of oil-containings can be generated during defeated, refining and oily waste water treatment, half
Solid waste is referred to as greasy filth, its main component is oil, Ni Heshui.Solid particle size can be from insufficient micron in greasy filth
To several inches, most of between 1 to 100 micron, oily composition depends on crude oil type, oil plant structure and operating condition,
The composition of sludge may change over time and change.According to statistics, nearly 3,000,000 tons of Chinese festiva oil-producing mud, wherein the crude oil money contained
Source is about 600,000 tons or so.In greasy filth in addition to containing a large amount of aged crude oil, wax, colloidal substance, contain a large amount of benzene homologues, phenol
The poisonous and harmful substances such as class, anthracene, pyrene, Polychlorinated biphenyls and dioxin.Furthermore also contain a large amount of pathogen, helminth in greasy filth,
Such as without rationally effective processing, petroleum resources can be not only wasted, also environment can be caused seriously to pollute.
The technology of processing oily sludge mainly has resource reclaim, harmless treatment and comprehensive utilization technique etc. at present.Resource
Recovery processing technology includes solvent extraction, WATER-WASHING METHOD, micro emulsion washing, demulsification method etc..Greasy filth innoxious process for treating includes solid
Determining processing, the technologies such as biological treatment, burning.Comprehensive utilization technique includes thermal decomposition, brickmaking is paved the way and other purposes.
The advantages that active high, quick due to chemical demulsifier, adding demulsifier is most common demulsification side
Method.Currently used demulsifier is primarily present the disadvantages of oil recovery rate is low, and biological degradability is poor.
