Product type
Crude oil demulsifiers are specialty chemicals designed to separate water from crude oil emulsions. These compounds work by reducing the interfacial tension between oil and water, allowing for easier separation during processing. Typically formulated from non-ionic surfactants, they play a crucial role in enhancing oil recovery and improving the quality of crude oil before it is transported or refined.
| Chemical type | Non-ionic surfactants |
| Appearance | Clear to yellowish liquid |
| Solubility | Soluble in oil, insoluble in water |
| Temperature stability | Effective at temperatures up to 100°C |
| Dosage rates | Typically 0.1% to 2% of the total emulsion volume |
When selecting a crude oil demulsifier, consider the specific characteristics of the emulsion you are dealing with, including oil composition and water content. Specify the required temperature stability, dosage rates, and any necessary certifications for environmental compliance. It's also important to discuss the anticipated volume of product needed for your operations to ensure optimal performance and cost-effectiveness.
