Abstract
The present invention relates to a kind of demulsifier, belong to sewage treatment drug field.Including triethanolamine 50 100 parts, polyoxypropylene 45 85 parts, sodium hydroxide 10 60 parts, sodium phosphate 50 75 parts, Oleum Ricini 100 120 parts, methanol 0 30 parts, expoxy propane 300 400 parts, 200 350 parts of oxirane, 300 400 parts of glacial acetic acid, 200 400 parts of water.Compared to existing technology, the present invention has strong adaptability, breakdown of emulsion efficiency feature high, uncorruptible.
Description
Technical field
The present invention relates to sewage treatment drug, particularly to a kind of demulsifier.
Background technology
Along with the development of World Oil Industry, oil extraction increases day by day so that crude oil emulsion liquid measure increases day by day,
After water filling intensified oil reduction, water content in crude oil substantially increases, and major part crude oil is to exploit with water-oil emulsion form
Out.Containing substantial amounts of water and inorganic salt in crude oil Produced Liquid, bring great difficulty to oil-gas gathering and transportation and crude refining, because of
This must carry out being dehydrated, desalination.For produced problem during solution oil-gas gathering and transportation, it is necessary to use substantial amounts of chemical agent, at oil
Chemicals used in the process of gas collection is defeated is referred to as oil-gas gathering and transportation chemicals, and it is one of important oil field chemical, and it mainly has
Demulsifier, corrosion inhibiter, drag reducer, emulsifying agent etc..But, existing demulsifier on the market exists crude oil bad adaptability, breaks
Efficiency is low, be easily caused the problems such as corrosion for breast.
Summary of the invention
The technical problem to be solved: for shortcomings and deficiencies of the prior art, the present invention provides a kind of adaptation
Property strong, breakdown of emulsion efficiency demulsifier high, uncorruptible.
The present invention is designed such that a kind of demulsifier, it is characterised in that: the weight ratio of each component is: triethanolamine 50-
100 parts, polyoxypropylene 45-85 part, sodium hydroxide 10-60 part, sodium phosphate 50-75 part, Oleum Ricini 100-120 part, methanol 0-30
Part, expoxy propane 300-400 part, oxirane 200-350 part, glacial acetic acid 300-400 part, water 200-400 part.
Described triethanolamine weight ratio in each component is 95-98 part.
Described polyoxypropylene weight ratio in each component is 75-78 part.
Described sodium hydroxide weight ratio in each component is 22-25 part.
Described sodium phosphate weight ratio in each component is 60-63 part.
Described Oleum Ricini weight ratio in each component is 102 parts.
Described methanol weight ratio in each component is 12 parts.
Described expoxy propane, oxirane weight ratio in each component are 250-260 part.
By above-mentioned design, the present invention can bring following beneficial effect:
The demulsifier that the present invention provides includes triethanolamine, polyoxypropylene, sodium hydroxide, sodium phosphate, Oleum Ricini, first
Alcohol, expoxy propane, oxirane, glacial acetic acid, water, can be rapidly dispersed in crude oil, has good breakdown of emulsion to crude oil emulsion
Performance.Meanwhile, demulsifier dewatering speed is fast, dehydration rate is high for this, aqueous phase oil content is low, can tackle various crude oil, emulsion
Process, applied range.
