Demulsifiers can remove water from crude oil and heavy oil to meet the required water content standards. They break down emulsions, causing the dispersed phase to coagulate and separate. These agents disrupt the structure of emulsified liquids, achieving the separation of various phases in the emulsion. Below are the product advantages of demulsifiers: 1. Excellent water solubility, completely dissolving within 3 minutes. 2. Capable of demulsifying and dehydrating severely emulsified, highly acidic, high-wax-content, and highly water-absorbent water-in-oil sludge with a water content of around 50%, reducing it to below 10%, thereby recovering a significant amount of oil. 3. Low chemical dosage with high efficiency in salt removal and dehydration, offering substantial economic benefits. 4. Dehydration efficiency can reach 95%, with the product being non-polluting, safe, and reliable to use.
