Description

A kind of extracts composition, extraction system and its application
Technical field
The present invention relates to a kind of extracts composition, extraction system and its application.
Background technology
Lithium not only has important application in national defense industry, and its importance in national economy is also increasingly shown, especially It is in energy field：6Li and7Li be respectively following fusion reactor fuel and nuclear fission reaction used in important materials：It makees It is also growing for the demand of battery material.Therefore, lithium has the title of " energy metal of 21 century ".Both at home and abroad to the demand of lithium Sustainable growth, therefore the research and development to lithium resource utilizes and seems extremely urgent.
Salt lake bittern is the valuable source of lithium.China has abundant salt lake bittern lithium resource, before its reserves occupies the world Row.But due to containing various metals ion in bittern, it is comprehensively utilized and the technology of separation and Extraction lithium is desirable from bittern The important topic of research, especially for containing high concentration magnesium, low concentration lithium so-called " high Mg/Li ratio " bittern in separation and Extraction Lithium, it is generally acknowledged worldwide technological puzzle.
Solvent extraction technology is the effective technology of the various metals of separation and Extraction from solution, and it has separative efficiency height, work Skill and equipment are simple, operate serialization, are easily achieved the advantages that automatically controlling, it is considered to be are extracted from " high Mg/Li ratio " bittern One of most promising method of separating Li.Since last century middle nineteen sixties, oneself proposes some extractor bodies both at home and abroad System and technique, it is specific as follows：
(1) 1967 year, NelliJ.R. etc. invented a kind of extraction system and technique [1.Nelli J.R.etal.Fr.1, 535,818(1967)；USP3,537,813(1970).]：FeC1 is added in bittern3As co-extraction agent, with 80% 2 isobutyl The tributyl phosphate of ketone -20% is as organic phase, by Li and Fe with LiFeC14Form coextraction enters big in organic phase, with aqueous phase Measure MgC12And other metals separation.Though extraction of the system to Li has higher selectivity, be stripped with water produce LiCl and FeC13Mixed liquor, di-(2-ethylhexyl)phosphoric acid-tributyl phosphate system extract and separate Li and Fe again must be used, causes technique Tediously long, cumbersome, so far there are no, and it is used for industrial production.
(2) 1979 years, Qinghai Salt Lake research institute of the Chinese Academy of Sciences proposed the kerosene with single extracts composition tributyl phosphate Solution extracts the system and technique of lithium, so as to simplify extraction system, and has been carried out in 1984 from big bavin denier salt lake bittern The pilot-plant test of lithium is extracted, having applied for Chinese invention patent in 1987, [3. yellow teachers are strong etc., Chinese invention patent, CN, N- bis- Hexyl propionamide 7103431], and authorized.But the extracts composition employed in the system is tributyl phosphate, It is stronger to the corrosivity of extraction equipment, and the tributyl phosphate not only solution loss in water, and in acidity in long-term operating Easily degraded in medium, particularly its serious swelling action to the material for making extraction equipment limits its industry Large-scale application.
(3) CN, N- dihexyl benzamide 3055539A disclose a kind of method that lithium salts is extracted from bittern containing lithium, its The extraction of lithium is carried out using co-extraction agent, extracts composition and diluent, it is rotten to equipment to solve first two extraction system and technique The problem of corrosion is difficult to industrialization by force, and achieve preferably extraction and back extraction performance.But this method is in industrialization process In it is still pure in problems, as single-stage extraction rate is relatively low, influence yield and yield, extraction must be increased by wanting to obtain higher yields Series；The separation of lithium and magnesium, sodium, potassium is not big enough, and the product directly obtained can not reach high-purity requirement, it is necessary to which increase is washed Wash series or other post processing modes.
Therefore, the extraction that lithium salts is extracted from bittern containing lithium and back extraction performance how are further improved, it is cost-effective, more Suitable for industrialized production, turn into this area and need technical problems to be solved badly.

For interrupted extraction process, organic phase volume V (m are extracted3) and feed liquid aqueous phase L (m3) the ratio between be referred to as comparing；For even Continuous extraction process, extraction phase volume flow V (m3/ s) and feed liquid phase volume flow L (m3/ s) the ratio between also referred to as compare or two phase flow Than unified herein to represent two-phase volume or flow with O/A.Represented compared to R：
In formula：VoFor the volume of extraction phase, VaFor the volume of feed liquid phase
(2) extraction yield
Extraction yield, which represents to be extracted material in extraction process the amount of extraction phase is mutually transferred to by feed liquid, to be accounted for and is extracted material in original The percentage of total amount in feed liquid phase, it represents the degree of extract and separate.Extraction yield E (%) calculation formula is：
In formula：naTo be extracted the amount of material, n in feed liquidoTo be extracted the amount of material in extraction raffinate.
(3) distribution ratio
Distribution ratio is also known as distribution coefficient.It is extracted distribution behavior of the substance A in two-phase and can be understood as A in two-phase The gross effect of existing variform A1, A2 ..., An distribution.Under normal conditions, measured value of experiment is extracted in representing per phase Take the total concentration of a variety of existing forms of material.System distribution coefficient is defined as under certain condition, when system reaches balance, quilt The ratio between total concentration of the extracting substance in extraction organic phase (O) and total concentration in feed liquid phase (A), are represented with D：
Distribution ratio represents that extraction system is extracted actual allocation proportion of the material in two-phase after reaching balance, typically by reality Test is determined.It is bigger by the distribution ratio of extraction thing, show that the material is more easily extracted, while the size of distribution ratio except with by extraction thing Property has outside the Pass, also relevant with extraction conditions, as by extraction thing concentration, acidity, the other materials coexisted, extracted in aqueous phase in organic matter Take the species and concentration of agent, temperature when species of diluent and extraction etc. is relevant.
(4) separation factor
Under certain condition carry out extract and separate when, two kinds of materials to be separated two alternate distribution coefficients ratio, Referred to as extract and separate factor, also known as extract and separate coefficient, commonly use β and represent.If A, B represents two kinds of materials to be separated respectively, have：
In formula：DAFor the distribution ratio of A materials, DBFor the distribution ratio of B substance.
Extract and separate quantifies illustrate the complexity of two kinds of materials in some extraction system separating material liquid phase.β value For 1 when both materials can not be separated, β value is bigger or smaller, and separating effect is better, i.e. the separation selectivity of extractant is got over It is high.
