In recent years, with the introduction of crude oil into the middle and late stages, the content of colloid and asphaltene in crude oil has increased, making the crude oil emulsion more stable. With the continuous development and application of oil recovery technology, a large number of surfactants are used to drive oil and make crude oil. The composition of the oil has become more complicated, and the salt content of crude oil produced by oil fields has increased year by year, which has aggravated the task of dehydration and desalination of crude oil. Therefore, the performance of demulsifier is one of the important conditions for achieving high-efficiency electric desalination of crude oil. The crude oil demulsifier developed by our company is a high-efficiency non-ionic surfactant product, which is composed of various oil-soluble and water-soluble dry agents and effective additives. A liquid that is compatible with a certain ratio. The product has the characteristics of fast breaking speed, low water content after oil removal, high salt rejection rate and small dosage.
At present, the company has developed a series of JB type demulsifiers to meet the requirements of different types of crude oil desalination and dehydration.
In December 2014, our company carried out industrial application in CNOOC Nanhai Oilfield. The oilfield use data shows that the use of our company demulsifier can effectively improve the dehydration and desalination effect, the highest dehydration rate is 99%, the dehydration pass rate is 100%, the desalination rate can reach 98%, the salt content after stripping is ≤5mg/L, the pass rate is ≥80% .
Demulsifier is a surface active substance which can destroy the emulsified liquid structure to achieve the separation of the phases in the emulsion. Crude oil demulsification refers to the use of the chemical action of the demulsifier to remove the oil and moisture from the emulsified oil-water mixture to achieve the purpose of dehydration of the crude oil to ensure the water supply standard of the crude oil.
The most effective and effective method for the effective separation of the organic phase and the aqueous phase is to use a demulsifier to eliminate the emulsification to form an emulsified interface with a certain strength to achieve two-phase separation. However, different demulsifiers have different ability to break the organic phase, and the performance of the demulsifier directly affects the two-phase separation effect. In the production process of penicillin, an important procedure is to extract penicillin from the penicillin fermentation broth with an organic solvent (such as butyl acetate). Since the fermentation broth contains complexities such as proteins, sugars, mycelia, etc., the organic phase and water are extracted. The interface of the phase is unclear, and the emulsified zone has a certain strength, which has a great influence on the yield of the finished product. To this end, it is necessary to use demulsifier demulsification to eliminate emulsification and achieve rapid and effective separation of the two phases.
This product is water-soluble or oil-soluble surfactant, with a strong surface activity, good wetting properties and sufficient flocculation and coalescence ability to adsorb to all types of crude oil emulsion oil water. membrane interface, significantly improve the interface properties, significantly reduce the interfacial film strength and effectively implement emulsion breaking, dehydration.

Demulsifier is a nonionic crude oil demulsifier polymerized from propylene oxide and ethylene oxide. It is compatible with various effective auxiliaries. It has no irritating odor, is slightly toxic, has low viscosity, and is easy to transport, fill and clean. Good, non-corrosive, no special materials required for storage and filling.
This product can be directly used by the demulsifier injection system, or diluted with water or other solvents to a certain concentration. The amount added depends on the process system, the type of crude oil and other process parameters (typically about 60 to 100 ppm).
