Why choose extraction?
2018-07-10
  • Zhengzhou TIEI EXTRACTION Technology Co.,Ltd. special in the design and supply liquid-liquid extraction equipment engineered to fulfill the chemical, pharmaceutical, biotech and falovor & frangrance industries' increaingly challenging purification requirements.

Liquid-liquid extraction is a powerful separation technique that falls right behind distillation in the hierarchy of separation methods.

If a separation can be made economically by distillation, there is no reason to consider extraction. However, in situations where distillation is not feasible for reasons such as a complex process sequence, high investment or operating costs, heat sensitive materials, or low volatility, extraction is often the best
technology to use.


For Example:
 

  1. Separation not feasible by distillation slide

  2. Break azeotropes

  3. Energy requirements of distillation are prohibitive

  4. A complex distillation sequence is required

  5. The material is heat sensitive

  6. The material is non-volatile

 

  • Liquid-liquid extraction technology could be used in many fields:
 

1.Pharmaceutical Industry (Raw material of medicine, medical intermediate)

For example:

Raw material of medicine, reaction liquid of medical intermediate or solvent continuous extraction and washing; Organic phase and aqueous phase continuous separation; Natural medicine extraction(Such as artemisinin, caulis sinomenii, bilobalide and so on);

Antibiotics (Such as penicillin, lincomycin, gibberellin and so on);

Vitamin extraction (Such as pantolactone and so on).

2.Fine Chemicals/Petrochemical Industry

For example:

Chemical intermediate, raw liquid of pesticide and other reaction liquid and solvent continuous extraction and washing and so on,

Organic phase and aqueous phase continuous separation;

Lube oil purification and extraction, Diesel oil purification and extraction.

3.Food Fermentation Industry

For example:

Lactic acid fermentation broth extraction, Citric acid fermentation broth extraction, Natural plant pigment extraction (Such as chlorophyll) and so on.

4. Hydrometallurgy Industry

Chemical metal element extraction and separation (Such as Nickel, Cobalt, Copper, Zinc, Rubidium, Cesium, Manganese and so on);

Rare earth element separation and extraction;

Lithium and Boron extraction from Brine

5.Wastewater Treatment

For example:

Phenolic wastewater treatment, Printing and dying wastewater treatment(Such as H acid, K acid and so on), DMF wastewater treatment, Hight concentration chemical organic wastewater treatment, Naphthalene sulfonic acid wastewater treatment and so on.

7. Oil And Water Separation ( Both Include remove oil from water and remove water from oil).
