DEMET C-168 by UNPChemicals: A High-Performance Equivalent to Nouryon Witbreak DRC-168 for Efficient Demulsification

In the petroleum industry, the efficiency of oil-water separation directly impacts operational costs, equipment safety, and environmental compliance. Demulsifiers, as core chemicals for breaking stable oil-water emulsions, have become a critical link in crude oil production, transportation, and refining processes. Among the numerous demulsifier products on the market, Nouryon Witbreak DRC-168 has long been recognized for its reliable performance in handling complex emulsions, especially in harsh oilfield conditions. Responding to the market demand for high-quality, cost-effective alternatives, UNPChemicals is proud to launch DEMET C-168—a premium demulsifier that matches Nouryon Witbreak DRC-168 in every key performance indicator, offering oilfield operators a trustworthy and competitive solution.

Core Performance: Fully Aligned with Nouryon Witbreak DRC-168

UNPChemicals’ DEMET C-168 is developed through advanced molecular design and rigorous formulation optimization, with the goal of achieving complete performance equivalence to Nouryon Witbreak DRC-168. Extensive laboratory tests and field trials have confirmed that the two products share identical core functionalities and application effects, particularly in the following aspects:

1. Exceptional Emulsion Breaking Efficiency

Both DEMET C-168 and Nouryon Witbreak DRC-168 are polyether-based demulsifiers with a multi-branched molecular structure, enabling rapid adsorption at the oil-water interface. They efficiently displace natural emulsifiers such as asphaltenes and resins, reduce interfacial tension to the optimal range (avoiding microemulsion formation), and significantly lower the viscoelasticity of the interfacial film. In tests with light, heavy, and high-water-cut crude oils, DEMET C-168 demonstrated the same fast dehydration speed as Nouryon Witbreak DRC-168—achieving clear phase separation within 30-60 minutes under standard conditions, with the dehydrated crude oil water content meeting the pipeline transportation standard of ≤0.5%.

2. Wide Adaptability to Harsh Conditions

Oilfield operations often face extreme challenges such as high salinity (up to 200,000 ppm), wide temperature fluctuations (-10°C to 120°C), and varying crude oil properties. DEMET C-168, like Nouryon Witbreak DRC-168, exhibits strong environmental adaptability. It maintains stable demulsification performance in high-salinity brines and low-temperature environments, effectively handling emulsions formed in mature oilfields with high water cuts and offshore production platforms. Whether treating paraffinic, naphthenic, or asphaltenic crude oils, DEMET C-168 delivers consistent results, eliminating the need for frequent product replacement due to changes in crude oil composition.

3. Low Dosage and Cost-Effectiveness

Both products feature high activity, requiring only a low dosage (50-200 ppm) to achieve optimal demulsification effects. UNPChemicals’ strict quality control system ensures that DEMET C-168 has the same concentration of active ingredients as Nouryon Witbreak DRC-168, ensuring that customers can use the same dosage as Nouryon Witbreak DRC-168 to obtain equivalent results. Additionally, DEMET C-168 offers a more competitive price point without compromising performance, helping oilfield operators reduce chemical procurement costs while maintaining operational efficiency.

4. Compatibility with Other Oilfield Chemicals

In practical applications, demulsifiers often need to be used in conjunction with corrosion inhibitors, pour point depressants, and scale inhibitors. DEMET C-168 has undergone comprehensive compatibility tests, proving that it can be mixed with common oilfield chemicals without causing precipitation, degradation, or reduced efficacy—consistent with the performance of Nouryon Witbreak DRC-168. This compatibility ensures seamless integration into existing operational systems, minimizing the risk of process disruptions during product switching.

Raw materials are sourced from qualified suppliers and undergo rigorous purity testing; the production process is monitored in real-time using automated equipment to ensure stable reaction conditions; and each batch of finished products is tested for key indicators such as demulsification speed, water content after separation, and adaptability to harsh conditions—with test data archived for traceability. This strict quality management system ensures that DEMET C-168 provides consistent, reliable performance batch after batch, just like Nouryon Witbreak DRC-168.

Field Application Cases: Proven Equivalence

The performance equivalence of DEMET C-168 to Nouryon Witbreak DRC-168 has been verified through numerous field applications in oilfields across Asia, Africa, and South America. For example, a large oilfield in the Middle East previously used Nouryon Witbreak DRC-168 to treat high-salinity, high-water-cut crude oil emulsions. After switching to UNPChemicals’ DEMET C-168, the field observed no significant difference in dehydration speed (remaining at 45 minutes per batch) and the water content of the treated crude oil remained below 0.3%, meeting the refinery’s feedstock requirements. Additionally, the dosage remained the same (120 ppm), resulting in a 15% reduction in chemical procurement costs for the oilfield.

Another case involves an offshore oilfield in Southeast Asia, where harsh conditions such as high temperature (90°C) and strong emulsion stability posed significant challenges. Nouryon Witbreak DRC-168 was previously used with good results, but the high procurement cost was a concern. After testing DEMET C-168 in a pilot project, the oilfield found that the new product achieved the same separation efficiency, with the water phase clarity and oil recovery rate identical to those of Nouryon Witbreak DRC-168. The successful pilot led to full-scale adoption of DEMET C-168, generating annual savings of over $200,000 in chemical costs for the oilfield.
