The Importance of Petroleum Demulsifier in Industrial Production

Petroleum demulsifiers play a key role in the petroleum industry, and their core mechanism of action and practical applications are mainly reflected in the following aspects:

firstly, the demulsification mechanism adjusts the interfacial tension by rapidly dispersing surface active ingredients to the oil-water interface, significantly reducing the interfacial tension (which can be reduced by more than 50%), causing the emulsion film to rupture, water droplets to aggregate and settle. Charge neutralization and coagulation of acidic demulsifiers disrupt the stability of emulsifiers through ion exchange, while alkaline demulsifiers break down the emulsion layer by adjusting the pH value. Both can accelerate oil-water separation.

2、 Industrial application value: Optimizing crude oil production to improve crude oil dehydration efficiency, achieving a standard water content of ≤ 0.5% for export, increasing oil recovery rate by 5-15%, directly improving economic benefits, equipment and process protection to prevent pipeline blockage and pump valve wear caused by emulsion, extending equipment life by more than 30%, reducing subsequent treatment agent dosage, reducing sludge oil content, and supporting environmental compliance to effectively separate emulsified oil from wastewater (removal rate>90%), meeting discharge standards.

• Performance advantages, fast response: Most demulsifiers can complete oil-water separation within 30 minutes. Broad spectrum adaptability: suitable for different pH values (2-12) and temperature conditions (-20 ℃ to 150 ℃). Economy: Compared with traditional methods, it can reduce processing costs by 20-40%. Note: In practical applications, the type of demulsifier needs to be selected according to the characteristics of the crude oil (such as API degree and salt content). It is recommended to determine the optimal dosage through laboratory trials (usually 50-500ppm).

SD8022 Lubricating Oil Demulsibility Characteristics Tester is suitable for measuring the ability of oil and water to separate in medium and high viscosity lubricating oils. Lubricating oil anti emulsification tester complies with GB/T8022. ASTM D2711

Using digital tube temperature display, easy to use and operate.

The instrument can simultaneously separate one sample.

Adopting PID temperature control technology, the temperature control accuracy is high.
