Abstract
The present invention relates to a kind of demulsifiers, belong to sewage treatment drug field.Including 50 100 parts of triethanolamine, 45 85 parts of polyoxypropylene, 10 60 parts of sodium hydroxide, 50 75 parts of sodium phosphate, 100 120 parts of castor oil, 0 30 parts of methanol, 300 400 parts of propylene oxide, 200 350 parts of ethylene oxide, 300 400 parts of glacial acetic acid, 200 400 parts of water.Compared with prior art, adaptable strong, efficient, the uncorruptible feature of demulsification of the present invention.
Description
Technical field
The present invention relates to sewage treatment drug, more particularly to a kind of demulsifier.
Background technology
With the development of World Oil Industry, oil extraction increasingly increases so that and crude oil emulsion liquid measure increasingly increases,
After water filling intensified oil reduction, water content in crude oil obviously increases, and most of crude oil is exploited in the form of water-oil emulsion
Out.Contain a large amount of water and inorganic salts in crude oil Produced Liquid, great difficulty is brought to oil-gas gathering and transportation and crude refining, because
This must be dehydrated, desalination.To solve the problem during oil-gas gathering and transportation, it is necessary to a large amount of chemical agent is used, in oil
Chemicals used in the process of gas collection is defeated is known as oil-gas gathering and transportation chemicals, it is important one of oil field chemical, mainly has
Demulsifier, corrosion inhibiter, drag reducer, emulsifier etc..But existing demulsifier on the market exists to crude oil bad adaptability, breaks
Newborn efficiency is low, easily leads to the problems such as corrosion.
Invention content
The technical problems to be solved by the invention:In view of the deficiencies of the prior art and defect, the present invention provide a kind of adaptation
Property strong, efficient, the uncorruptible demulsifier of demulsification.
What the present invention was designed so as to:A kind of demulsifier, it is characterised in that:The weight ratio of each component is:Triethanolamine 50-
100 parts, 45-85 parts of polyoxypropylene, 10-60 parts of sodium hydroxide, 50-75 parts of sodium phosphate, 100-120 parts of castor oil, methanol 0-30
Part, 300-400 parts of propylene oxide, 200-350 parts of ethylene oxide, 300-400 parts of glacial acetic acid, 200-400 parts of water.
Weight ratio of the triethanolamine in each component is 95-98 parts.
Weight ratio of the polyoxypropylene in each component is 75-78 parts.
Weight ratio of the sodium hydroxide in each component is 22-25 parts.
Weight ratio of the sodium phosphate in each component is 60-63 parts.
Weight ratio of the castor oil in each component is 102 parts.
Weight ratio of the methanol in each component is 12 parts.
The propylene oxide, weight ratio of the ethylene oxide in each component are 250-260 parts.
By above-mentioned design scheme, the present invention can bring following advantageous effect:
Demulsifier provided by the invention includes triethanolamine, polyoxypropylene, sodium hydroxide, sodium phosphate, castor oil, first
Alcohol, propylene oxide, ethylene oxide, glacial acetic acid, water can be rapidly dispersed into crude oil, have good demulsification to crude oil emulsion
Performance.Meanwhile the demulsifier dewatering speed is fast, dehydration rate is high, water phase oil content is low, can cope with various crude oil, emulsion
Processing, has a wide range of application.
