Abstract
The invention discloses a kind of oil-sludge treatment demulsifiers, it by weight part include following components: 10-20 parts of sodium hydroxide, 10-20 parts of propylene oxide, 1-10 parts of triethanolamine, 1-10 parts of sodium phosphate, 5-15 parts of magnesium sulfate, 1-5 parts of toluene diisocyanate, 5-15 parts of oleic acid, 1-10 parts of sodium nitrite, 10-20 parts of polyoxyethylene ether, 1-5 parts of organic inhibitor.The raw material of product of the present invention is commercial product, and demulsifier demulsification obtained is high-efficient, and adaptability is extensive, and usage amount is few, and the temperature that is demulsified is low, is not required to added electric field, has the characteristics that small dosage, high treating effect, reduces operating cost.
Description
Technical field
The invention belongs to chemical fields, and in particular to be a kind of oil-sludge treatment demulsifier.
Background technique
It is an important link in oil and gas industry oilfield exploitation procedure that Oil/Gas Pipe trace gather is defeated, to solve oil gas
The problem during collecting defeated, it is necessary to use a large amount of chemical agent, chemicals used in the process of oil-gas gathering and transportation is known as oil
The defeated chemicals of gas collection, it is important one of oil field chemical, mainly there is demulsifier, organic inhibitor, drag reducer, emulsifier
Etc..The chemical agent that emulsification crude oil demulsification can be made to be dehydrated is crude oil demulsifier, since emulsified crude oil has Water-In-Oil emulsified crude oil
With oil-in-water emulsified crude oil two types, therefore crude oil demulsifier also divides two types, i.e., water-in-oil emulsion crude oil demulsifier and
Oil-in-water type cream people's crude oil demulsifier.Water-in-oil emulsion crude oil demulsifier has low molecular weight demulsifier and high molecular weight demulsifier, low
Molecule demulsifier mainly has fatty acid salt, alkyl sulfate salt, alkylbenzene sulfonate, OP type surfactant etc., macromolecule
Demulsifier mainly has polyoxyethylene sodium hydroxide alkyl alcohol ether, polyoxyethylene sodium hydroxide phenol-amine resin etc..Oil-in-water type emulsion
It is former
Oily demulsifier mainly has hydrochloric acid, sodium chloride, magnesium chloride, calcium chloride, methanol etc..Existing demulsifier on the market exists to original
Oily bad adaptability, easily leads to the problems such as corrosion at the low efficiency that is demulsified.
Summary of the invention
It is an object of the invention to overcome problem above of the existing technology, a kind of demulsifier is provided, is possessed good
Demulsification system.
To realize above-mentioned technical purpose and the technique effect, the invention is realized by the following technical scheme:
A kind of oil-sludge treatment demulsifier includes following components by weight part: 10-20 parts of sodium hydroxide, propylene oxide 10-20
Part, it is 1-10 parts of triethanolamine, 1-10 parts of sodium phosphate, 5-15 parts of magnesium sulfate, 1-5 parts of toluene diisocyanate, 5-15 parts of oleic acid, sub-
1-10 parts of sodium nitrate, 10-20 parts of polyoxyethylene ether, 1-5 parts of organic inhibitor.
Preferably, by weight part include following components: 15 parts of sodium hydroxide, 16 parts of propylene oxide, triethanolamine 8
Part, 3 parts of sodium phosphate, 12 parts of magnesium sulfate, 2 parts of toluene diisocyanate, 7 parts of oleic acid, 2 parts of sodium nitrite, 16 parts of polyoxyethylene ether,
2 parts of organic inhibitor.
Preferably, the organic inhibitor is the one of phosphine carboxylic acid, coloured glaze base benzothiazole, benzotriazole or lignosulfonate
Kind.
The beneficial effects of the present invention are:
The raw material of product of the present invention is commercial product, and demulsifier demulsification obtained is high-efficient, and adaptability is extensive, and usage amount is few,
And demulsification temperature is low, is not required to added electric field, has the characteristics that small dosage, high treating effect, reduces operating cost.
