The application of demulsifiers in industrial production

Demulsifier is a surfactant that can destroy and disperse emulsions. It is commonly used in industrial production to treat wastewater containing emulsions, oil-water separation, and emulsion separation in various liquid mixing systems. Below, we will provide a detailed introduction to the application of demulsifiers in industrial production.

1、 Wastewater treatment:

Steel smelting wastewater treatment: The wastewater generated during the steel smelting process often contains high concentrations of emulsions. By adding demulsifiers, these emulsions can be destroyed and dispersed, allowing them to precipitate and separate, thus achieving the treatment and recycling of wastewater.

Oil refining wastewater treatment: The wastewater generated during the oil refining process also contains a large amount of emulsion, and demulsifiers play the same role here, effectively reducing the oil content in the wastewater and improving water treatment efficiency.

Textile wastewater treatment: Textile wastewater contains emulsion suspended solids such as fibers, pigments, dyes, etc. By adding demulsifiers, these emulsion suspended solids can be destroyed and dispersed, facilitating the subsequent treatment process.

2、 Oil water separation:

Construction site drainage treatment: Construction site drainage contains a large amount of suspended solids and oil substances. By adding demulsifiers, these substances can be destroyed and dispersed, promoting the separation of oil and water, thereby achieving purification treatment of construction site drainage.

Oilfield wastewater treatment: Oilfield wastewater contains a large amount of oil substances, which can be destroyed and dispersed by adding demulsifiers, making it convenient for subsequent treatment processes to separate and purify oil and water.

Industrial wastewater treatment: Industrial wastewater often contains various emulsion suspended solids, which can be destroyed and dispersed by adding demulsifiers, promoting oil-water separation and wastewater purification treatment.

3、 Emulsion separation in liquid mixing systems: In some industrial production processes, emulsion liquids are often produced in liquid mixing systems, such as chemical reaction systems and emulsions in food processing. By adding demulsifiers, these emulsions can be destroyed and dispersed, making it easier to extract and separate products.

4、 Other applications:

Sludge dewatering: During the sludge dewatering process, the water contained in the sludge often exists in the form of an emulsion. The addition of demulsifiers can achieve sludge dewatering and water separation.

Polymer treatment: In the production process of polymers, it is often necessary to treat reactant systems containing emulsions. By adding demulsifiers, the emulsions can be destroyed and dispersed, improving the yield of polymers and the quality of products.
