Oilfield Demulsifier for Crude Oil & Water Separation | CNPS
Demulsifier – Accelerated Oil & Water Separation for Crude Oil Systems
Product Overview
The CNPS Demulsifier is a high-performance chemical designed to accelerate the separation of oil and water in crude oil production and processing systems. It effectively destabilizes water-in-oil emulsions, reduces water content in crude oil, and improves downstream processing efficiency. This product is widely applied in oilfield production, gathering, storage, and transportation systems, especially where emulsion problems lead to reduced throughput, higher treatment costs, or corrosion issues.
Key Advantages
- Rapid Emulsion Breaking — Effectively separates water-in-oil emulsions, reducing dehydration time and improving crude oil quality.
- Broad Applicability — Suitable for paraffinic, naphthenic, and mixed crude oils with varying water content and salinity levels.
- High Efficiency at Low Dosage — Optimized formulation provides excellent performance even at low injection rates, lowering chemical consumption.
- Compatible with Oilfield Additives — Works well alongside corrosion inhibitors, scale inhibitors, and pour point depressants without interference.
- Easy Application — Can be injected continuously or in batch treatment systems; stable and easy to handle in field operations.

- Crude Oil Production – separating water from production fluids
- Oil Gathering & Transportation – preventing emulsion-related flow issues
- Storage & Tank Farms – improving crude oil quality before shipment or refining
- Refinery Pre-Treatment – reducing water content for downstream processing
Injected directly into the emulsion stream using continuous dosing or batch treatment through standard chemical injection equipment.
Initial recommended range: 50 – 500 ppm (recommended range, not a guaranteed value). The optimal dosage should be optimized based on laboratory bottle tests or field trials, considering crude oil type, water cut, and salinity.
🔧Compatibility / Performance
Works well alongside corrosion inhibitors, scale inhibitors, and pour point depressants without interference. Performance on paraffinic, naphthenic, and mixed crudes with varying water content and salinity should be validated through bottle tests or field trials for the specific crude.
⚙️Safety & Handling
Handle with standard personal protective equipment (gloves, goggles). Avoid contact with skin and eyes. Follow site chemical-handling procedures and the safety data sheet information confirmed at the time of purchase.
💎Packaging & Storage
Store in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources. Keep containers tightly closed to prevent contamination and moisture ingress. Packaging configurations, container sizes, and shelf life are to be confirmed with CNPS at the time of inquiry.
