How to select extraction equipment?
2018-07-10
There are more than 30kinds of extraction equipments in industry. Various of equipments have different characteristics, and the effects of various factors in extraction process and extraction system are complicated, so that to choose the suitable extraction equipment is very important in liquid-liquid extraction process.

For extraction equipment selection, you could refer to the flowing principle:

  1. Stability and residence time;

  2. Clarification characteristics of solvent system;

  3. Equipment cost and maintenance;

  4. Theoretical stage requirements;

  5. The area covered by the equipment and building height;

  6. Handling capacity;

  7. The system physical property.

The comment extraction equipments are mixer settler, extraction column, centrifugal extractor. And we have made feasibility report to these equipments, found that centrifugal extractor is the ideal in effect, adaptation, volume efficiency, space occupied, emulsifying ability.

Especially CWL-M series of centrifugal extractor, it is a new type of liquid-liquid extraction and separation equipment, with our own independent intellectual property rights and patents. it has essential difference in principle with traditional extraction equipments such as mixer settler, extraction column and so on.

Centrifugal extractor adopt motor to drive the bowl with high-speed rotation, under the condition of shear force generated by bowl or blade rotation, two different density and immiscible liquids complete mixing and mass transfer; and separated rapidly by centrifugal force generated by high-speed rotation of
bowl.



Advantages Of CWL-M series of Centrifugal Extractor

  Our CWL-M series of centrifugal extractor is our independent R&D equipment with patents, it is different with other traditional extraction equipments, with many advantages, For example:

  1. Simple and stable structure

  Top-suspension structure, no bearing and mechanical seal at the bottom, no leakage risk, easy to maintain and save maintenance cost, long service life;

  2. Energy-saving

  Large capacity, more energy-saving (under the same capacity condition, the power consumption is 1/10-1/3 of the annular type);

  3. Corrosion resistance

  Equipment could adopt perfluoro polymer material, resistant to strong acid (hydrochloric acid, mixed acid etc.);

  4. Good effect of mixing and separation

  Various hybrid structures could be chosen, good separation effect, adapt to easily emulsified system;

  5. Easy to change heavy phase weir

  When changed liquid system, heavy phase weir could be replaced quickly, simple and easy operation;

  6. Low liquid residual

  Equipment with small valid volume;

  7. High automation

  It could realize timely monitoring on line, optional on-line cleaning system for GMP standard, and adapt to both intermittent and continuous running completely.

Application Of CWL-M series of Centrifugal Extractor

  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).
