Extraction Principles

Wherein the solvent extraction operation with a component from a liquid mixture known liquid / liquid extraction.Extraction is the use of the difference in the choice of the components of the solubility of the solvent solution of that solute in the liquid-liquid mass transfer, to achieve a homogeneous liquid mixture separation operation.Full operation of the extraction process can include:

1.Raw material mixing liquid extraction agent in contact with the completion of the solute mass transfer process;

2.Extract phase and raffinate phase separation process;

3.Phase extraction solvent recovery process from the extraction phase and raffinate.Usually recovered by distillation.

Now to extract containing A, B mixture of two components A component as an example of the process of extraction operations.A suitable choice of solvent S, the solvent extraction of a component A should want significant ability to dissolve the other components B should be totally insoluble or partially miscible (solubility smaller the better).S is called the chosen solvent extraction agent.The mixture to be separated (with A + B) is called a raw material liquid, wherein the component A is called the extracted solute, another component B (the former solvent) is called a diluent.

Three-step extraction process:

(1) First, the raw material liquid (A + B) and the amount of extractant S mixed in a mixer.Since B is immiscible with the S, S and the presence of (A + B) of the two liquid mixers.Stirring, causing large phase interface, so that the two-phase full contact by diffusion of solute A raw material liquid (diluent B) through the S phase interface in the extraction agent.A gradually decreased such that the concentration in the raw material liquid, and gradually increased in the S phase.After a certain time, the concentration of the two phases A no longer change with the growth of time, called the extraction equilibrium.

(2) after sufficient mass transfer, the liquid has a density difference of the two, may be allowed to stand for delamination by centrifugation, in order to achieve the purpose of separation.S in the main extractant, and large amounts of dissolved solute A in a phase called the extract, expressed in E; diluent and containing a small amount of B is not based diffusion of solute A is called a raffinate phase, represented by R .

(3) is usually recovered by distillation S.S phase after removal of extraction called extract; raffinate phase after removal of S is called raffinate.

Works

Mixing and separation machine set in one, compact structure.With centrifugal acceleration of liquid having a specific gravity difference - liquid two-phase separation.And fusion of the two liquid phases from each of two feed nozzle into the outer chamber of the rotor, the rotation of the rotor by means of rapid mixing.After passage through the liquid mixture into the bottom of the rotor inside the rotor.The rotor has an internal self-priming function is divided into four vertical cavity fluid into balance with each other.Liquid in the rotor flow from the bottom up process of gradual separation.

From the separation zone with the baffle plate until light weir to ensure there is enough time to form a liquid - liquid interface.The separated liquid - liquid phase respectively, through light and heavy phase weir together to the respective collecting chamber, and is discharged from each outlet, respectively.Heavy phase weir plate can be removed to replace the board to change the diameter of the weir.



Features

1 small footprint - direct drive motor, no transmission accessories, compact, space-saving footprint and operations;

(2) adapt to the strong performance - compared with conventional extraction equipment van and tower, grade retention time is short, phase quickly adapt to a wide range of flow ratio; through exchange weir plate and frequency control to meet the different density The viscosity of the liquid material;

3 high extraction efficiency - equilibrium established fast, easy to implement single-stage or multi-stage countercurrent or crossflow series washing and extraction;

4 operating performance is good - fully automatic operation, continuous operation without interruption, but also the use of small quantities of many varieties;

5 investment costs low - machine small volume, extraction, solvent or detergent consumption minimum;

6 airtight performance - to meet the explosion and toxic and hazardous volatile medium and easy application environment and GMP norms;

7 Optional multi - machine can be configured according to the different needs of the anti-emulsification device cleaning mechanism in place (CIP), inverter etc.

When using the hydrometallurgical extraction process, especially when you need a lot of progression or non-equilibrium extraction can be used when the application of centrifugal extractors have good prospects.Centrifugal extractor for extraction equipment to reduce the area occupied by the plant, reducing the extraction process of extracting agent retention volume extraction system from start to shorten the time and is conducive to the stability of automatic control and other aspects have a significant effect.

 

In other traditional industries to replace traditional extraction equipment applications is very broad application prospects are very good.
