Pour Point Depressant (PPD) for Waxy Crude Oil | CNPS
Pour Point Depressant – Improved Cold-Flow Performance for Waxy Crude Oil
Product Overview
The CNPS Pour Point Depressant (PPD) is a specialized oilfield chemical designed to improve crude oil flowability at low temperatures. By modifying wax crystal formation and preventing crystal aggregation, the PPD effectively lowers the pour point of crude oil, reduces viscosity, and enhances cold-flow performance. This product is widely applied in oil production, gathering pipelines, storage, and transportation systems operating under low-temperature conditions.
Key Advantages
- Effective Pour Point Reduction — Significantly lowers crude oil pour point, improving fluid mobility and reducing the risk of pipeline blockage.
- Improved Flow Assurance — Controls wax crystal growth and dispersion, ensuring stable flow during cold weather operations.
- Wide Crude Oil Compatibility — Applicable to paraffinic and waxy crude oils with different wax contents.
- Good Chemical Compatibility — Compatible with common oilfield chemicals such as corrosion inhibitors, demulsifiers, and scale inhibitors.
- Easy Application — Suitable for continuous or batch injection; easy to handle and deploy on-site.

Injected directly into crude oil via continuous dosing or batch treatment using chemical injection systems.
Typical dosage range: 50 – 500 ppm (typical/recommended range, not a guaranteed value). Optimal dosage should be determined based on crude oil wax content and temperature profile.
🔧Compatibility / Performance
Compatible with common oilfield chemicals such as corrosion inhibitors, demulsifiers, and scale inhibitors. Pour point reduction performance (up to 10 – 30 °C) is a typical/upper value and depends on the specific crude oil's wax content, as well as treatment and operating conditions; confirm effectiveness on your crude through laboratory testing.
⚙️Safety & Handling
Use appropriate personal protective equipment (PPE). Avoid prolonged 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 heat sources and direct sunlight. Keep containers tightly sealed to prevent contamination and moisture ingress. Packaging configurations, container sizes, and shelf life are to be confirmed with CNPS at the time of inquiry.
