Высокоэффективный экстракт лития из рассола

SX technology has obvious advantages in lithium recovery from high magnesium content brines, such as larger throughput capacity, easier setting up, simpler process, lower operating cost. However, solvent loss and lithium stripping using very high acidic solution are troublesome problems for the SX application. A new SX system and an according process were developed at IPE, CAS, with water used as the stripping agent. In addition, the new system can lower the solvent loss. Therefore, troublesome problems for the SX application were successfully overcome.

1. A synergistic system formed by double functional extractants;
2. Li water stripping without changing organic compositions;
3. Lower water solubility, good phase separation, fast kinetics, lower price etc.

1. Li water stripping significantly simplified tis recovery, reduced operating cost;
2. Improved phase separation, reduced or eliminated crude formation;
3. Stabilized operation with centrifugal contactor, and without any risk of corrosion by strong acid.

1. Mixed and mass transfer process

1. Li could be completely extracted with extraction near 100%
2. Li stripping: >95%,Li in loaded strip liquor: >20g/l
3. Purity of Li2CO3 product: >98%(industrial grade),but easy to achieve electronic grade by water washing.

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.

1. Oil water separation( crude oil/heavy oil/diesel and so on except water, salt);
2. Pharmaceuticals( such as used for ethyl acetate, methylene dichloride, normal butanol, choroforom and so on);
3. Extraction of chinese traditional medicine;
4. Pesticide(malathion extraction and so on);
5. Bioengineering(nutrient solution extraction and interferon extraction and so on);
6. Chemical and fine chemical( catalyst extraction and so on);
7. Hydrometallurgy( used mutilstage extraction and back extraction and so on to extract nickel, copper, uranium and other rare metals);
8. Food( edible oil, spice, refined oil, food color and so on);
9. Perfume industry;
10.Printing and dyeing industry( printing and dyeing wastewater treatment and recycle);
11.Environmental protection( used multistage extraction and back extraction and so on technology to treat wastewater with phenol, oil-water separation of marine sewage, groundwater separation or extraction or purification and so on);
12. Cosmetics industry( to extract nutrient ingredient);

Zhengzhou Tiantyi Extraction Technology Co.,Ltd. is a scientific and technological enterprise that integrated R&D, manufacturing and sales, mainly focus on developing and applying equipment of liquid-liquid mixing and separation. And contraction on related supporting project. 

Cooperated with Zhengzhou University, CAAC,USTB, Beijing Institute of Petrochemical Technology, etc. 

Awarded more than 20 patents, with advanced processing equipment, rigorous quality control system, top-quality talents and perfect service system, we are committed to providing comprehensive solution for every customer.

Tianyi groud setting One extraction application research center, One extraction pilot-plant experimental base and Two advanced production center at the moment, owned more than 30advanced mechanical process equipment, awarded more than 20patents.The patent number is ZL2014205865573.

Our company mainly focuses on the research and development of new and efficient extraction machine, and the application in chemical, hydrometallurgy, food, pharmaceutical industry etc. In extraction industry, there is more and more requirements for the extraction equipment, with the production scale expands and the new technology used. So R&D new type extraction machine is necessary, especially cooperating with various of related departments, to design new product which according to modern industrial production.
Innovation related enterprise development, and our company regard technology research as or driving force all the time. In 2006, in order to meet new market requirements, we established extraction application technology research center cooperate with Harbin Institute of Technology (local famous university in extraction fields). At the same time, we cooperate with many other famous university closely, grasping the new research trends, combined new extraction effect and new equipment design, theory serve for practice. At the moment, The maximum bowl diameter of our centrifugal extractor has been reached 800mm, ahead of the industry level. We will march forward courageously and continuously, to push the extraction industry forward.
