Product Introduction：

Oilfield wastewater demulsifier is a type of high-molecular-weight polymer and functions as a chemical agent capable of breaking oil-water emulsions. Oilfield wastewater originates from diverse and complex sources. During petroleum extraction, it is primarily generated from the separation of water-bearing crude oil, backwashing of water-injection wells, cleaning of storage tanks, backwashing of pressure filters at wastewater treatment facilities, condensation processes, and various operational activities such as drilling and hydraulic fracturing.

This wastewater contains crude oil, soluble gases, solid suspended solids, electrolytes, bacteria, and various oilfield chemical additives. It is characterized by high salinity (mineralization), high oil content, abundant microorganisms, and elevated levels of suspended solids.

The primary function of a demulsifier is to disrupt the emulsion structure in the wastewater, enabling effective separation of oil and water. It achieves this by altering the interfacial properties of the oil-water dispersion system, thereby destabilizing the emulsion and facilitating phase separation. Additionally, the demulsifier neutralizes the surface charge on emulsified oil droplets, causing them to lose colloidal stability, breaks down the protective emulsifying film surrounding the oil droplets, and modifies the interfacial tension between oil and water—promoting coalescence and efficient separation of the wastewater phases.

Product Advantages：

Remarkable Performance: The demulsifier rapidly disrupts the emulsified structure in wastewater, enabling clear oil-water stratification and significantly reducing oil content within a short period. It effectively separates oil-water mixtures, thereby enhancing overall wastewater treatment efficiency. Additionally, it promotes the coalescence and separation of oil droplets, facilitates the settling and removal of suspended solids, and efficiently eliminates oil, suspended matter, and other contaminants from the wastewater. This leads to a substantial reduction in pollutants such as chemical oxygen demand (COD), ammonia nitrogen, and heavy metals, ultimately improving water quality to meet regulatory discharge standards.

Excellent Adaptability: It is effective across a wide range of oilfield wastewater types, including those with high salinity, high oil content, high hardness, and other challenging characteristics.

Ease of Operation: Rapid demulsification and purification of wastewater can be achieved through simple dosing and mixing.

Low Cost: It offers excellent cost-effectiveness, enabling efficient wastewater treatment while keeping operational costs well controlled.

Service Industries：

Oil Extraction Industry: It is widely used in various stages of oilfield operations—including oil production, water injection, blowdown, and equipment cleaning—to treat wastewater generated during the extraction process.

Petroleum Refining Industry: It is used to demulsify oily wastewater generated during the refining process, achieving effective oil-water separation and purification.

Petrochemical Industry: Wastewater discharged from integrated petrochemical plants has a complex composition; demulsifiers can effectively treat such oily wastewater.

Other Industries: It can also be used for cleaning petroleum equipment and pipelines, reducing oil adhesion and enhancing cleaning efficiency. Additionally, it is applicable to treating various types of oily wastewater, such as cutting fluid wastewater, drilling wastewater, and mechanical workshop effluents. Furthermore, light industries, food processing facilities, and catering establishments—any sectors that generate oily wastewater—may also benefit from its use.
