Abstract
The invention relates to a formula of a high-flashing-point water-soluble demulsifying agent. The high-flashing-point water-soluble demulsifying agent comprises the following chemical raw materials in parts by weight: 30-50 parts of epoxypropane oxirane block polymer, 20-40 parts of alcohol solvent and 20-40 parts of water. The flashing point of the water-soluble demulsifying agent prepared by replacing methyl alcohol with the high-flashing-point alcohol solvent is greater than or equal to 65 DEG C, and the water-soluble demulsifying agent has relatively strong surface activity and relatively good hydrophilcity and lipophilicity. The high-flashing-point water-soluble demulsifying agent can be used for greatly reducing the risks of production, storage, transportation and field use, which are caused by a low-flashing-point demulsifying agent using methyl alcohol and water as solvents in a crude oil gathering and transportation process, and more importantly, the high-flashing-point water-soluble demulsifying agent can be used for solving the problem that the flashing point does not meet the safe export requirements.
Description
Technical field
The present invention relates to a kind of preparation formula of high flash point water-soluble demulsifier.
Background technology
Water-soluble demulsifier is a kind of oilfield additive generally using in crude oil transmission process on current oil field, be mainly used in the breaking emulsion and dewatering of crude oil mining fluid, utilize the chemical action of emulsion splitter that oil and water in the oil-water mixture of emulsification shape are separated, make it to reach the object of dehydrating of crude oil, to guarantee that crude oil exporting contains water quality standard.The effective constituent of domestic water-soluble demulsifier is propylene oxide ethylene oxide block polymkeric substance, use first alcohol and water as solvent cut after gained.
The common water-soluble demulsifier flash-point using on oil field is generally 20 ℃ of left and right, lower flash-point has brought application risk on the one hand production, storage, transportation and on-the-spot use of emulsion splitter, easily cause security incident, dilute on the other hand emulsion splitter methanol solvate used, human body is had to strong toxicity, central nervous system is had to anesthetic action, also optic nerve and retina are had to special selective action.The more important thing is, along with water-soluble demulsifier promoting the use of on world wide, especially at the scene temperature is higher than the equatorial country of 30 ℃, and the flash-point of common water-soluble demulsifier has not reached the requirement of fire exit, has greatly limited the outlet of emulsion splitter.
The present invention does not meet mainly for water-soluble demulsifier product low-flash the problem that fire exit requires, and a kind of high flash point water-soluble demulsifier product is provided.
Summary of the invention
The object that the present invention will reach:
First object of the present invention is that a kind of solvent that can replace the methanol solvate in water-soluble demulsifier product will be provided;
Second object of the present invention is flash-point >=65 ℃ of water-soluble demulsifier product of will giving security; ;
The 3rd object of the present invention is to guarantee that other physical and chemical indexes of water-soluble demulsifier product meet environmental requirement;
Technical scheme of the present invention:
A formula for high flash point water-soluble demulsifier, this formula is comprised of the chemical feedstocks of following weight ratio, 30～50 parts, propylene oxide ethylene oxide block polymkeric substance, 20～40 parts of alcoholic solvents, 20～40 parts, water.
Compound method: each component, by said ratio, is fully mixed in mixing tank.
This formula is by changing the ratio of alcoholic solvent and water, meeting the high flash point requirement of emulsion splitter.
Beneficial effect of the present invention:
1, meet the high flash point requirement of outlet demulsifier product, and the environmental requirement that meets outlet point of destination.
2, reduce emulsion splitter producing, store, transport and the on-the-spot application risk bringing that uses, avoid the generation of dangerous accident.
