Product Specification

Demulsifiers, or demulsifying agents, are essential in petroleum refineries and extraction processes, where they help separate water from crude oil emulsions. Here’s a brief overview of their key applications:

1. Crude Oil Dehydration: Demulsifiers break oil-water emulsions formed during extraction, allowing efficient water removal from crude oil before further processing in refineries.

2. Enhanced Processing Efficiency: They expedite oil-water separation, reducing treatment time and improving overall operational efficiency in refineries, which minimizes downtime and processing costs.

3. Preventing Equipment Corrosion: By removing water, demulsifiers help protect refining equipment from corrosion, which extends equipment life and reduces maintenance needs.

4. Improving Product Quality: Effective water removal enhances the quality and stability of crude oil, ensuring compliance with refinery quality standards for downstream processes.

5. Environmental Compliance: Demulsifiers assist in managing wastewater by removing residual oils, ensuring that discharged water meets environmental regulations and reduces the ecological impact.

Product Overview

This product is a reverse emulsifier, a composite polymer water treatment agent characterized by numerous positively charged groups along its molecular chain. It is a highly effective cationic polymer. With its powerful reverse emulsification capability, it can significantly lower the interfacial tension of oil-in-water (W/O) or water-in-oil (O/W) emulsions. This process destabilizes the emulsions by neutralizing the repulsive and attractive forces of oils or colloidal particles in wastewater, resulting in the formation of flocs. Through further chemical bridging, it facilitates the separation of oil and water, as well as the removal of harmful impurities in the wastewater, achieving the goals of oil recovery and wastewater purification. The emulsifier is highly effective in breaking water-in-oil emulsions, reducing oil-water separation time, and is water-soluble and effective across a broad pH range.

Applications

• Separation of oilfield produced water and polymer-laden wastewater in petroleum extraction
• Demulsification of emulsified liquids and cutting fluid wastewater from mechanical machining and metal manufacturing
• Demulsification of emulsified liquids and alkaline wastewater from steel mills
• Oil-water separation of coking wastewater from coking plants
• Oil-water separation of animal and vegetable oil wastewater from leather and fur processing
• Removal of organic substances from high-concentration organic wastewater in chemical industries

Physical and Chemical Properties

Usage Instructions

Add the product directly to the wastewater either in its original form or diluted, then stir and allow it to settle. For optimal results, use in conjunction with PAC and PAM. The ideal pH range for application is 5-12, with pronounced demulsification and flocculation effects around pH=9. The dosing point is typically selected in the rapid mixing tank of the sewage treatment process. The dosage varies depending on the type of wastewater, generally ranging from 50-1000ppm.
