With the continuous growth of global demand for oil, oilfield mining activities are becoming more and more frequent. However, the treatment of oilfield produced water has become an important environmental issue. Produced water usually contains a large amount of oil, suspended solids and other pollutants. If it is discharged directly without proper treatment, it will cause serious pollution to the environment. Demulsifier, as an important oilfield produced water treatment agent, can effectively separate the oil-water mixture and improve the treatment effect of produced water.
Demulsifier is a sewage treatment agent that can neutralize the charge on the surface of emulsified oil droplets in wastewater, causing it to lose stability, destroy the emulsified film on the surface of emulsified oil droplets, change the tension of the oil-water interface, promote the aggregation and separation of wastewater, and thus achieve demulsification of wastewater and oil-water separation.
Demulsifiers are widely used in oilfield produced water treatment, mainly including the following aspects:
1. Oil-water separation: Demulsifiers can effectively separate oil-water mixtures and improve the treatment effect of produced water.
2. Remove suspended matter: Demulsifiers can promote the aggregation and separation of oil droplets, thereby driving the precipitation and removal of suspended matter.
3. Reduce COD: Demulsifiers can effectively remove organic matter in produced water and reduce COD content.
4. Improve water quality: Demulsifiers can effectively remove oil, suspended matter and other pollutants in produced water, improve water quality and meet discharge standards.
When using demulsifiers, you need to pay attention to the following issues:
1. The amount of demulsifier added: The amount of demulsifier added needs to be reasonably determined according to the properties and treatment process of produced water.
2. The method of adding demulsifiers: The appropriate method of adding demulsifiers needs to be selected according to the treatment equipment and treatment process.
3. The mixing time of demulsifiers: The mixing time of demulsifiers needs to be reasonably determined according to the performance and treatment process of the demulsifiers.
4. Storage and transportation of demulsifiers: Attention should be paid to the storage conditions and transportation methods of demulsifiers to avoid deterioration and failure of demulsifiers.
As an important oilfield produced water treatment agent, demulsifier can effectively separate the oil-water mixture and improve the treatment effect of produced water. When using demulsifier, it is necessary to consider factors such as the nature of produced water, the performance of demulsifier, treatment process and cost, and pay attention to the amount of demulsifier added, the addition method, mixing time, storage and transportation, etc.
