The one step exchange process of carrying out between two kinds of liquid phases by means of exchange media is known, and this method has been used the system of two chambers.A kind of liquid phase exchange media has all been filled in two chambers, and exchange media forms continuous phase.Feed decentralized photo in each chamber, this decentralized photo does not dissolve in exchange media, but feeds in the exchange media as a kind of drop.Thereby material is transferred to the exchange media from decentralized photo (extraction phase) in a chamber.This exchange media is imported in another chamber.Import another kind of decentralized photo (absorption phase) through exchange media in this chamber, material is transferred in the absorption mutually from exchange media.For example at " theoretical foundation of Chemical Technology " magazine, (Moskau) 1984, B.18; The 6th phase, this method is disclosed in the 736-738 page or leaf.
The separative efficiency of a disclosed step material exchange processes is still waiting to improve.A kind of improving one's methods is to expand to multistep processes.
By Russ P application number 95117738 and 95117767 known a kind of multistep material exchange processes that on October 19th, 95 proposed, this method is being carried out in a series of classification step that run through each other between two kinds of liquid phases by means of a kind of exchange media.In this case, each classification step comprises two contact connected to one another chambers.Exchange media has been filled in these chambers.Extraction phase that disperses, be insoluble to continuous exchange media or absorption are passed through these chambers with drop group's form.Exchange media successively with first Room in extraction phase and the absorption in second Room contact.At this moment the material that need separate is transferred in second Room by first Room, is transferred in the absorption mutually by extraction phase.In order to improve mass exchange, a plurality of this classification step that run through each other are set.This method is called extraction-extract again combined techniques.Exchange media is an extractant.
The application potential of this known multistep material exchange processes and separative efficiency also are still waiting exploitation, for example expand to gas-liquid exchange or solid-liquid exchange.
The objective of the invention is to develop improving one's methods of a kind of known substance exchange process with other using value.In order to improve the separative efficiency of the mass exchange between two kinds of liquid phases, this method comprises the process of carrying out by means of exchange media and the cohesive process of absorption, absorption and desorb in different states of matters.
The objective of the invention is to realize by following form, extraction phase is contained in first Room of a step, and will absorbs in second Room that is contained in a step mutually according to above-mentioned one-step method and multistep processes.Exchange material with exchange media, at first exchange media is assigned in the chamber that extraction phase is housed, then be assigned to one and be equipped with in the chamber that absorbs phase.
Exchange media circulates between first and second Room in same step at every turn.
Another kind method is that exchange media also can circulate in a plurality of or whole classification step, is transported in first Room of next step by second Room of a step.
Extraction phase is with absorb mutually can be with following current or adverse current form by a series of classification step.
Be method of the present invention astoundingly by improve between each step chamber or between a plurality of classification step chamber the circulation rate of exchange media can improve separative efficiency.
Describe the present invention in detail by means of embodiment and accompanying drawing below.Wherein:
Fig. 1 is the process chart of the classification step that runs through continuously, comprise exchange media in step circulation and liquid phase through the adverse current route of all classification step.
Fig. 2 is the process chart of the classification step that runs through continuously, comprise exchange media in step circulation and liquid phase through the following current route of all classification step.
Fig. 3 is the process chart of the classification step that runs through continuously, comprise exchange media through in steps circulation and the adverse current route of the classified step of liquid phase.
Fig. 4 is the process chart of the classification step that runs through continuously, comprise exchange media through in steps circulation and liquid phase through the following current route of this step.
In the method for Fig. 1 and Fig. 3, first Room and second Room that constitute classification step are set in the housing separately.
In the method for Fig. 2 and Fig. 4, first Room and second Room that constitute classification step are placed in the housing superimposedly, and classification step is overlapping in a housing.
In all technological operations, corresponding liquid phase all is equipped with in the contact chamber of classification step.In first Room 1 extraction phase is housed, in second Room 2 the absorption phase is housed.Then exchange media between the chamber in classification step (Fig. 1 to 2) or circulate by a series of classification step (Fig. 3 to Fig. 4).Like this by exchange media is assigned to chamber 1 and chamber 2 mutually in, contact fully between making exchange media and extraction phase or absorbing mutually.Exchange media distribution in each phase is to carry out with the form of drop, bubble, particle, Fig. 2 schematic diagram for example, but also can injection stream and the form of film carry out Fig. 4 schematic diagram for example.Exchange media can be liquid, gas or solid.
Extraction phase through pipeline 3 be transported to first classification step chamber 1 in, discharge from last classification step through pipeline 4.Absorb through pipeline 5 and carry, discharge through pipeline 6.The pipeline 7 one-level one-levels ground of extraction phase through connecting is carried, and carries and absorb through connecting line 8 one-level one-levels ground.Pipeline 9 circulations of exchange media through connecting.
Exchange media is indoor mobile in contact, is undertaken by gravity from the top or the bottom outflow of chamber.Exist very big difference mutually and between the exchange media at extraction phase and absorption.According to this big difference, exchange media is collection chamber 1 and the bottom (Fig. 1,4) of chamber 2 or the top (Fig. 2,3) of chamber 1 and chamber 2 in being assigned to corresponding liquid phase the time, forms phase boundary 10.Exchange media in the contact chamber 1 and 2 is assigned in the liquid phase through distributor 11.Physical characteristic according to exchange media realizes various distribution, for example carries out with the form of drop, bubble, particle or injection stream and plume.
The material that needs to separate is transferred in the exchange media by extraction phase in chamber 1, is transferred in the absorption mutually by exchange media in chamber 2.The material of flowing through in the extraction phase of chamber 1 by this method reduces, and the material in the absorption mutually of the chamber 2 of flowing through increases.
Extraction phase passes through classification step with following current (Fig. 2,4) or adverse current (Fig. 1,3) form mutually each other with absorbing.The following current route implements simple industrial.But when the material that need to separate as quick as thought with absorb mutually or during its contained component reaction, they can only arrive a maximal efficiency.
In mass exchange method of the present invention, extraction phase forms continuous phase with absorbing in contacting the chamber, fill most of space of chamber.Make thus two kinds in the indoor time of staying length than known method, exchange media further fills up the chamber.The longer time of staying is favourable, because can carry out the mass exchange of longer time, makes exchange more abundant thus.If mass exchange is accompanied by chemical transformation, so this method is particularly important, and chemical transformation can not disappear as quick as thought.
