Liquid-liquid extraction is a classic chemical unit operation, widely used in chemical industry, pharmaceutical industry, hydrometallurgy, nuclear fuel cycle and other fields. In the water-based Purex process, a large number of extraction methods are used for co-decontamination, separation and purification of key nuclides. Centrifugal extractor, as a new type of extraction equipment, has shown significant advantages in these applications.

Centrifugal Extractor

The working process of the centrifugal extractor is mainly divided into two parts: mixing mass transfer and centrifugal phase separation. The core is to use the strong centrifugal force generated by high-speed rotation to make the extractant and the liquid fully contact and complete the mass transfer process in a short time. Subsequently, the two-phase liquid is quickly separated by the action of centrifugal force. Centrifugal extractor have the following advantages:

  1. Short residence time: Due to the action of centrifugal force, the two-phase liquid can be quickly mixed and separated, greatly shortening the residence time.
  2. Small retention volume: Compared with traditional mixer settlers and pulse extraction columns, the centrifugal extractor requires a smaller volume of retention liquid, reducing the use of organic solvents.
  3. High efficiency: A single-stage extractor can achieve a higher separation effect, greatly improving the processing capacity.
  4. Large processing capacity: The centrifugal extractor can handle a larger flux of liquid, which is particularly suitable for the treatment of highly radioactive materials.
  5. Wide operating range: Suitable for a variety of liquid materials with different densities and viscosities.

Application of Centrifugal Extractor

Centrifugal extractor is widely used in many fields due to their unique performance advantages, including but not limited to chemical, pharmaceuticals and petrochemical.

  1. Chemical industry: synthesis of fine chemicals, wastewater treatment (removal of pollutants such as phenols and heavy metals)
  2. Pharmaceutical industry: extraction and purification of antibiotics, vitamins, and natural products.
  3. Nuclear industry: separation of radioactive substances in nuclear fuel reprocessing.

In recent years, China has also increased its research and development efforts in centrifugal extraction technology. Zhengzhou Tiei Extraction has launched the CWL-M Series Centrifugal Extractor with high separation factors and strong stability. For strong acid, strong alkali, and strong corrosive occasions, full anti-corrosion reinforced materials can be selected. Centrifugal Extractor has shown excellent application prospects in many fields such as new energy and new materials, hydrometallurgy, and environmental governance.
