Precision Application of Demulsifiers in Industrial Systems

The efficacy of demulsifiers in industrial water treatment hinges on dosing methods, system compatibility, and environmental stability. Key strategies for Chemi Tech demulsifiers include:

1. Precision Dosing and Location

Settling Tanks: Use slow-acting demulsifiers (e.g., high-MW polyethers) for sufficient contact time;

Rapid Separation: Inject fast-acting types (e.g., low-MW quaternary salts) at pipeline mixers or electric dehydrator inlets;

Physical Enhancement: Combine with air flotation or centrifugation to accelerate oil rise and solid settling.

2. Process Synergy

High-Salinity Adaptation: Sulfonated asphalt derivatives maintain efficacy in Cl >5000 mg/L environments;

Sludge Control: Reduce demulsifier dosage to 0.005%-0.02% when compounding with inorganic flocculants (e.g., PAC) to minimize sludge volume.

3. Stability and Cost Efficiency

Temperature Tolerance: Mineral-oil products remain stable at 5°C-50°C without crystallization or degradation;

Storage Management: Emulsion types require mechanical stirring to redisperse settled active components;

Longevity: Modified silicone polyethers provide 24-hour sustained demulsification, reducing dosing frequency by 30%.

Process coordination (e.g., pH adjustment to 6-9 for optimal interfacial activity) and real-time monitoring (e.g., >90% clarified water transmittance) significantly enhance operational efficiency. Feel free to contact via +8619820415595.
