In laboratory research and development within the petrochemical, fine chemical, and oil processing industries, oil washing to remove impurities is a key step for evaluating oil quality and optimizing process routes. Traditional laboratory washing often relies on manual shaking with separatory funnels, which suffers from inconsistent operation, severe emulsification, and exposure to volatile organic compounds. To meet the demand for multi-stage laboratory washing and extraction, Zhengzhou Tiei’s CWL50-M small-scale centrifugal extractor provides an efficient, continuous, and controllable experimental platform for oil washing process development.
CWL50-M Centrifugal Extractor Principle: Reconstructing Oil-Water Contact with Centrifugal Force
The CWL50-M centrifugal extractor operates on the principle of an enhanced centrifugal force field. High-speed rotation generates centrifugal force that thoroughly mixes the oil and water phases at a micrometer scale before rapidly separating them. A single run completes the entire “mixing, mass transfer, and centrifugal separation” process. Compared with traditional manual shaking and static separation in a separatory funnel, the CWL50-M centrifugal extractor improves efficiency by 5–8 times, while offering continuous operation, controllable parameters, and excellent repeatability.
Core Advantages of the Centrifugal Extractor
1.Precise Process Simulation
The CWL50-M centrifugal extractor can directly simulate multi-stage countercurrent and multistage crossflow extraction processes using only small sample volumes. Whether screening single-stage washing conditions or validating multi-stage cascaded processes, the CWL50-M centrifugal extractor provides accurate and reliable scale-up data.
2.Outstanding Demulsification Capability
Addressing the common emulsification issues in oil washing, the CWL50-M centrifugal extractor achieves rapid and clear separation of oil and water phases through its powerful centrifugal force. This effectively prevents the accumulation of emulsified layers and ensures the quality of the washed oil.
3.Compact and Flexible Design
The CWL50-M centrifugal extractor features a compact design (dimensions: 400 × 370 × 900 mm), occupying a footprint of only 0.15 m², and requires minimal auxiliary equipment. Its rotational speed is continuously adjustable within the range of 2,270 to 2,840 rpm, allowing for the optimization of operating parameters to suit varying oil viscosities and density differences.
4.Fully Enclosed and Safe Operation
The fully enclosed design allows oil and wash water to mix and separate within a closed system, preventing the release of volatile organic compounds and ensuring the health and safety of laboratory personnel.
5.Wide Material Compatibility
The drum is integrally formed from imported composite fluoropolymers, and the machine body is made of high-performance hybrid polymer materials. This ensures resistance to corrosion from various oils and acidic or alkaline wash media, meeting the demands of diverse oil washing processes.

Application Case
At the R&D center of a petrochemical company, technicians used the CWL50-M centrifugal extractor to validate a heavy oil desalting process. The original process employed a three-stage washing with separatory funnels, taking 3 hours per batch with noticeable emulsification. After switching to the centrifugal extractor:
Three-stage countercurrent washing time reduced to 15 minutes
Desalting rate increased from 92% to 98.5%
Wash water consumption reduced by 40%
Process data repeatability: RSD < 3%
