Solvent extraction liquid liquid separation process

Traditional liquid liquid extraction apparatus extractor is a new type, fast and highly efficient liquid-liquid extraction separation equipment, it is different with traditional extraction equipment such as mixer settler, extraction tower . Centrifugal extractor using the motor driven drum to reach high speed, the densities of different and not mutually mixed solution of two liquids in drum or blade rotation shear stress under complete mixing and mass transfer, and in high-speed rotation drum of centrifugal force under the action of rapid separation 

1. Mixed and mass transfer process

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.

1. Equipment material will be chosen according dto the feed physico-chemical property, common used SS304/316L/904L, common composite material, fluoride material and so on;
2. Above table is general parameter, real device has a little devitation, please refter to the matched technological manual;
3. Above flux is under ideal condition, ratio of oil and water is their flux sum when 1:1.

Liquid-liquid extraction, also known as solvent extraction, is one of the important unit operations in the separation of liquid mixtures. To add a kind of liquid extractant which is immiscible or part of miscibility with the liquid mixture to be separated, formed two phases system including liquid phase and extract, using of the difference of distribution of each component in the mixture in the two phases to make some components enter into the extract more from liquid phase, and then realized the separation of mixed liquor, which is called liquid-liquid extraction.

CWL-M series Liquid liquid centrifugal separator released by zhengzhou tianyi extraction technology co.,ltd used for phenolic wastewater, and turning the waste into treasure. This series extractor is our the 4th product with our independent intellectual property rights, and patent number: ZL2014205865573. Under the same handling capacity, this series of machine energy consumption is 10%~30% of traditional annular type. At the same time, and it has short duration, split phase velocity, high extraction rate, save cost and solvent could be recycled and reused.

1. R&D, manufacture and sale on extraction and mixing equipment;
2. contraction on related supporting project, such as planning layout on extraction production line, installation and adjustion on extraction equipment, construction on related construction facilities.
3. Project test in every stage, such as lab-scale test, pilot test etc.

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.

Such the flowing situation:
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
