NMP, N-methylpyrrolidone, is an organic compound with low volatility, good thermal stability and chemical stability, and can evaporate with water vapor. The compound is easily soluble in water, ethanol, ether, acetone, ethyl acetate, chloroform and benzene, and can dissolve most organic and inorganic compounds, polar gases, natural and synthetic polymer compounds. N-methylpyrrolidone is widely used in lithium batteries, medicines, pesticides, pigments, cleaning agents, insulating materials and other industries.

In chemical enterprises, chloroform is used to extract NMP from water. This process is a common operation unit. When extracting NMP, the choice of equipment is very important. We have a customer who consulted us. When the company used chloroform to extract NMP from water, it used traditional extraction equipment. The following problems occurred during the operation:

  1. The equipment operation is complicated and noisy.
  2. The liquid system is highly corrosive to the equipment.
  3. The extraction efficiency is low, the energy consumption is high, and the overall cost is high.

In response to the actual problems encountered by customers, our company has developed a detailed process and equipment plan for them. According to the liquid system and processing volume, we selected the CWL250-M new centrifugal extractor for the customer. This series of extractors has a small footprint, simple and convenient operation, customizable materials, corrosion resistance, high extraction efficiency, low energy consumption, and can greatly reduce the overall cost.

After conducting a small-scale experiment, the customer was very satisfied with the experimental data. The industrial production line has been operating in the customer's workshop and the equipment is running smoothly.

Advantages of centrifugal extractors

  1. High energy-saving effect.
  2. Small amount of equipment filler.
  3. Large processing capacity, high mass transfer efficiency, high stage efficiency.
  4. A variety of mixed structures are optional, suitable for easy emulsification system.
  5. Perfluorinated polymer material can be used for construction, which can resist corrosion of concentrated acid, hydrochloric acid, mixed acid and organic solvents.
  6. The contact time of two-phase materials is short, saving the investment cost of extraction agent.
