Crude Demulsifier

At present, the development of oil treatment demulsifier in oil fields at home and abroad presents various trends. In China, with the development of the ternary compound flooding technology, the components of crude oil emulsions have increased and the difficulty of oil-water separation has increased, posing higher requirements for the performance of demulsifier for crude separation.

In the future, attention should be paid to improving the ability of demulsifier oil to adapt to emulsion breaker oil and gas of different properties, strengthening the research on low-temperature demulsifier for crude separation, increasing the development of environmentally friendly emulsion breaker chemical and researching and applying supercritical CO2 demulsification and magnetized nano-demulsifiers, etc.

Abroad, the development of Emulsion breaker oil and gas also has many characteristics:

Non-polyether polymer oil treatment demulsifier are developing rapidly. They not only dehydrate quickly, have clear water color and have a small dosage, but are also particularly suitable for emulsion breaker oil and gas. Alternatives to epoxides have emerged and the research of non-polyether emulsion breaker oil and gas represents the development trend.

The relative molecular mass continues to increase and various chain extenders play a role. Currently, the more commonly used chain extenders abroad include aldehydes, di- or polycarboxylic acids, epoxy derivatives, and polyisocyanates. Another characteristic of demulsifier oil is that demulsifier oil have changed from water-soluble to oil-soluble. Because the water content in the produced fluid from oil fields is getting higher and higher, and oil-soluble demulsifier oil are mainly distributed in the oil which can prolong the action time and improve the demulsification effect.

Demulsfier for crude separation have changed from straight-chain linear to branched-chain linear from initiators of the hydroxyl series to phenolic resins and from initiators of the amino series to polyvinyl polyamines.

At the same time, combined use in oil treatment demulsifier is also an important trend. Organically combining two or several effective active ingredients can often achieve unexpected results.

In addition, demulsifier oil tend to be serialized. The compounded demulsfier for crude separation are not only suitable for various types of crude oil emulsions but also largely save the dosage of emulsion breaker chemical to achieve the purpose of reducing costs.

Overall, both at home and abroad, research is being conducted on oil treatment demulsifier with wide applicability to overcome the strong specificity weakness of emulsion breaker chemical .

Our factory has focused on customized demulsifier for over 20 years, including:demulsfier for crude separation, demulsifier oil and emulsion breaker chemical.
